Electroless nanocomposite platings were fabricated while the magnetic field strength and ultrasonic parameters were controlled. The effect of the complex field on the composite platings’ deposition process was discussed. The results show that composite coatings fabricated by a complex magnetic field had better density and homogeneity than coatings processed without the influence of external fields. The time-step deposition discussions indicate that the extra magnetic field accelerates the motion of the composite particulates in the bath through the action of the Lorentz force and promotes the nucleation and growth process of composite particulate clusters. The mechanical energy generated by the ultrasonic vibration activates the substrate surface and promotes the deposition of the Ni2+ in the plating solution on the substrate surface. While the complex field is functioning, ultrasonic and magnetic interactions play an important role in the fabrication of the uniform and dense nano-SiC/Ni-P composite coatings, which consist of amorphous spherical Ni-P/SiC particle clusters with 200 nm diameter. The nanoindentation hardness of these composite coatings was approximately 0.15 GPa.

The effect o f the complex field on the composite platings’ deposition process was discussed. The results show that composite coatings fabricated by a complex magnetic fie ld had better density and homogeneity than coatings processed without the influence o f external fields. The time-step deposition discussions indicate that the extra magnetic fie ld accelerates the motion o f the composite particulates in the bath through the action o f the Lorentz force and promotes the nucleation and growth process o f composite particulate clusters. The mechanical energy generated by the ultrasonic vibration activates the substrate surface and promotes the deposition o f the Ni2+ in the plating solution on the substrate surface. While the complex field is functioning, ultrasonic and magnetic interactions play an important role in the fabrication o f the uniform and dense nano-SiC/Ni-P composite coatings, which consist o f amorphous spherical Ni-P/SiC particle clusters with 200 nm diameter. The nanoindentation hardness o f these composite coatings was approximately 0.15 GPa. K eyw ords: electroless com posite plating, m agnetic field, ultrasonic wave. In tro d u c tio n . Nanocom posite coatings have excellent properties such as high hardeness and toughness, good w ear resistance and corrosion resistance by incorporating nanoparticles like A 12O3 [1, 2], M oS2 [3], and SiC [4]. These coatings have broad application prospects in m any fields, such as m echanical, aerospace, and transportation [5]. However, the traditional process of plating electroless com posites often results in unstable solutions, inefficient deposition, and higher processing temperatures. In order to improve the traditional process, new preparation technologies have been invented. N iksefat and Ghorbani [6] used an ultrasonic assisted electroless plating m ethod to prepare N i-B-TiO 2 com posite coatings w ith excellent perform ance. The same m ethod was im proved by Luo et al. [7] and Lu [8]. Zhong [9] applied the laser induced m ethod to fabricate N i-P/nano C60 on the surface of a sm ooth com ponent. The com posite coatings possessed small friction coefficients and high w ear resistance. W ang et al. [10] found that the deposition efficiency o f the com posite coating w as significantly increased in a 10 T parallel strong m agnetic field. Zhao et al. [2] successfully adopted the m echanical vibration assisted electroless com posite plating m ethod to obtain m ulti w alled carbon nanotubes reinforced w ith N i-P m atrix com posites coatings on the carbon steel surface, while M ehto and Pandey [11] prepared copper based nanocom posite films w ith the same method. In the electroless com posite plating process, the introduced ultrasonic w ave fields have the effect o f dispersing the solution system and increasing the reaction rate. In addition, the presence o f an electrom agnetic field im proves the deposition, nucleation, growth velocity and com pactness o f the coating. A t present, there are only a few reports globally about the study o f chem ical com posite plating technology w ith the help o f an ultrasound w ave and m agnetic field. Therefore, this w ork intends to explore the effect o f an electrom agnetic-ultrasonic com plex field on the plating o f electroless nanocom posite © H. Z. ZHOU, W. H. WANG, Y. Q. GU, X. X. FANG, Y.

W ithin this paper, the morphology, com position and structure o f the composite coatings are analyzed, and the effect o f the com pound field is summarized. 1. E x p e rim e n ta l P rocess an d C h a ra c te riz a tio n M ethods. 1.1. E xperim ental. The m atrix sample is a single side frosted glass w ith a size of 10x10 mm. The sample w as sensitized for 10 m in in a solution (30 m l/l HCl and 30 g/l SnCl2) at 50°C, and then the sample was activated for 10 m in in 40 m l distilled w ater (0.1 g PdCl2 and 2 m l HCl) at 30°C. The plating solutions w ere created according to the formula in Table 1. A fter that the solutions w ere stirred for 5 m in by an FS-1500 ultrasonic generator. Finally, the pretreated samples were im m ersed in the plating solution. Table 2 shows the param eters o f the SB-175 type m agnetic field generator and the FS-1500 type ultrasonic generator that were used during the experiment. 1.2. Characterization M ethods. The coating sam ples’ m icrom orphology was observed by JSM -6360LV SEM, and the com position was analyzed by G ENESIS2000XM S60 EDS. The phase analysis o f the coatings was carried out on a Bruker AXS D8-Advance X -ray diffraction instrum ent using Cu (Ka) target w ith an X -ray wavelength o f 0.15418 nm. The acceleration voltage was 30 kV, the step size w as 0.02 degrees, and the scanning speed was 1.2 °/min. The hardness o f the samples w as tested w ith a nanoindentation tester (Agilent G200). The indentation depth was 100 nm, and the loading tim e was 30 s.

Figure 1 shows an SEM image o f the frosted glass surface, from w hich we can see that the glass surface appears to be an irregular undulating structure after the grinding process. This undulating m orphology is beneficial to the deposition o f the com posite coating on the substrates. Fig. 1. SEM image of the frosted glass surface. 2.1. N anocom posite Coatings Prepared under D iffe ren t A dd itiona l F ields. Figure 2 shows SEM images o f the nanocom posite coating samples. As Fig. 2a shows, the surface o f sample No. 1 is undulating, the gaps betw een particles are large, and the aggregation phenom enon is obvious. In the sample shown in Fig. 2b, w hich was prepared under the action o f a m agnetic field during the plating process, the coating is tiny and compact. This can be attributed to the tendency o f N i particles to nucleate more effectively w ithin a m agnetic field. In Fig. 2c, the aggregation o f the deposited particles is not obvious, but there are still gaps. In Fig. 2d, the bottom layer o f No. 4 samples is com pact, and its surface consists o f m any spherical sediments. Fig. 2. SEM morphology of samples: (a) No. 1; (b) No. 2; (c) No. 3; (d) No. 4.

In general, it is difficult to create a uniform nanocom posite coating because agglom eration o f nanoceram ic particles [12] and aggregation o f the m etal nanograins [13-15] tend to occur. The experim entation in this w ork suggested that the aggregation phenom enon is nearly elim inated by inducing an electrom agnetic-ultrasonic field, w hich has m any im plications for the applications o f nanocom posite coatings. Figure 3a and 3b contain the energy spectra analyses o f the cross area on Fig. 2a and 2d. From Fig. 3a, it can be clearly seen that there are m ostly Ni, P, Si, and C elem ents in the coating, w hich indicates that the com posite coating is form ed on the glass substrate. Na, M g, Al, and other elem ents com e from the glass substrate, w hich indicates that the com posite coating is very thin. O n the other hand, the m ass fraction o f N i reached 63.96%, and the mass fraction o f Si decreased obviously in Fig. 3b, w hich states clearly that the com posite coating thickness is thicker. This phenom enon can be m ainly attributed to increased reaction rates and acceleration o f the particle g roups’ deposition on the glass substrate by the com pound field. Energy / keV b Fig. 3. EDS of samples fabricated under different additional fields: (a) No. 1; (b) No. 4. Figure 4 gives the XRD spectra o f Nos. 1 -4 com posite coating samples. Figure 4a and 4c show that the No. 1 and No. 3 coatings are obviously amorphous. However, the 2 theta angle o f N i at about 45 degrees m anifested a w eak diffraction peak in Fig. 4b and 4d, w hich indicates that the presence o f a m agnetic field in the com posite plating process had an obvious effect on the nucleation and deposition o f the coatings.

Figure 5 shows the SEM im ages o f Nos. 5 -8 coating samples. Figure 5 a -d shows that the surface o f each layer is denser than that o f No. 1, and the deposition o f particles is obvious. As the intensity o f the m agnetic field increased, the coatings becam e m ore com pact, and the globular trend o f the deposition products becam e m ore obvious. Thus, it can be concluded that the com pound field not only affected the spheroidizing o f deposition products, but also prom oted the densification o f the com posite coatings. Figure 5e gives the EDS results for the No. 8 sample. The m ain com ponents o f the m icrospherical particles in the coating are N i, P, Si, and C. Thus, the m icrosphere consists o f the co-deposition o f N i-P alloy and nano-SiC particles. A ccording to the uniform ity o f the m icrosphere morphology, the distribution o f SiC in the coating is also judged to be m ore uniform , and the SiC particles w ere seem ingly co-deposited w ith Ni-P.

Figure 6 gives the section SEM image o f sample No. 8. This image, along w ith Figs. 5c and 6, indicates that the coating on this sample is m ore uniform and compact. The coating also is made up o f m icrospheres that averaged 200 nm in size. The coating thickness was approxim ately 7.1 fim . Furtherm ore, the com bination betw een the com posite coating and glass substrate was good, and the coating’s m orphology w as independent o f the m atrix surface’s morphology. Fig. 6. Cross section SEM morphology of No. 8 sample. Figure 7 gives X RD results o f Nos. 5 -8 com posite coating samples. The diffraction peak in Fig. 7 leads to the conclusion that as the intensity o f the m agnetic field increased in the com pound field, the diffraction peak becam e increasingly sharp in the spectrum. This indicates that the crystal characteristic state o f the com posite coatings was increasingly evident. The related w ork o f X uan et al. [16] also reached a sim ilar conclusion. 20 40 BO 80 29 /deg Fig. 7. XRD of composite coating samples: (a) No. 5; (b) No. 6; (c) No. 7; (d) No. 8. The above analysis shows that w hen a com pound field w ith a certain intensity was introduced to the plating, a positive effect on the deposition process, structure and m orphology o f the deposited products w as achieved. The added ultrasound had two m ain effects. O n the one hand, a large num ber o f reactive free radicals could be generated in the reaction system, w hich could accelerate the rate o f the chem ical reaction [17, 18]. O n the other hand, the collision probability o f the N i ions in the plating solution is increased by the ultrasonic field, w hich m eans that the N i ions deposited on both the surface and the internal surface w ith catalytic activity. This helps to form uniform , com pact and im porosity 118 ISSN 0556-171X. npo6n.eubi 2017, N2 1 Study on the Fabrication o f Nano-SiC/Ni-P Composite Coatings com posite coatings. The energy provided by the additional electrom agnetic field accelerates the m ovem ent o f the N i particles in the plating solution. The N i ions are arranged according the direction o f the m agnetic field lines, and the ions can be deposited directly on the substrate in this direction [19]. The added m agnetic field not only prom otes the codeposition o f N i and SiC, but also m akes the m etastable phase o f the N i-P solid solution to grow in the preferred orientation. These results agree w ith the results o f the XRD analysis o f the coating in Figs. 4 and 7. 3. A nalysis o f N an o in d en ta tio n H ard n ess of th e C oatings. Figure 8 shows the relationship betw een the nanoindentation hardness and indentation depth o f different com posite coating samples. As can be seen from Fig. 8, the hardness values o f all samples decreased as the depth increased. The hardness values stabilized w hen the depth exceeded 20 nm. The hardness values o f samples Nos. 1 and 3 are nearly 0.50 GPa, while the hardness o f samples Nos. 4, 6, and 8 is relatively low (approxim ately 0.15 GPa). The extra ultrasonic fields had little influence on the m orphology and structure o f the deposited products during the deposition process, although they could prom ote deposition rates. Thus, the nanoindentation hardness values o f samples Nos. 1 and 3 are relatively close. On the other side, the extra electrom agnetic fields prom oted the form ation o f the orientation growing N i-P m etastable phase, w hich effectively reduced the average residual stress in the com posite coatings. However, the N i-P alloy coatings w ere not com pletely crystallized. Because the N i-P m etastable phase is different from that o f the stable phases, such as crystal N i3P form ed by the heat treatm ent, the hardness values o f samples Nos. 4, 6, and 8 are low er than those o f Nos. 1 and 3 samples. 4 .0 3 .5 3 .0 -0.5-1------- 1------- ,------- 1------- ,------- 1------- ,-------1------- ,------- 0 5 0 1 0 0 160 2 0 0 Indentation depth / nm Fig. 8.

The com bined fields o f eletrom agnetic and ultrasound waves have a significant effect on the deposition process, m icrostructure and the structural characteristics o f electroless N i-P based nanocom posite coatings. The N i ions in the plating solution are arranged according to the direction o f the m agnetic field lines, and the ions can be deposited directly on the substrate in this direction. Thus, the added m agnetic fields can m ake the m etastable phase o f the N i-P solid solution to grow in a preferred orientation in addition to im proving the deposition efficiency. The m echanical energy produced by the ultrasonic waves has a catalytic action and can accelerate the chem ical reaction. As the intensity o f the m agnetic field increases, the density o f the com posite coatings also gradually increases, and the spherical deposition trend o f the products and the preferred orientation growth becom e m ore obvious. Furtherm ore, the coatings’ nanoindentation hardness values are low er than those o f the coatings that w ere fabricated w ithout any external fields. ISSN 0556-171X. npoôneMbi 2017, № 1 119 H. Z.
