| description | The average destruction rates (Vs) were measured under the action of cavitation on a pre-production model from the alloy of Co-Cr-W on chemical composition near to the stellite No.6, its initial components and the coating obtained from a powder of the same composition using plasma generated by a plasma torch. It is established that the average destruction rate (Vs) of chromium, cobalt, tungsten is equal to 3.5; 0.72; 0.56 µm/h, respectively, and Co-Cr-W – 0.5 µm/h. After heat treatment of the Co-Cr-W alloy at a temperature of 1300 K for 3.6 ks, the value of Vs decreases to 0.28 µm/h. The plasma coating is destroyed at a speed of 1.3 µm/h, and steel 15Kh11MF – 2.4 µm/h. Under the action of cavitation in a corrosive environment, a 3% aqueous solution of sodium chloride Vs steel 15Kh11MF and Co-Cr-W alloy increases by 2 times.

The average fracture rates (Vs) were measured under the action of cavitation of a prototype of a Co-Cr-W alloy
with a chemical composition close to stellite No.6, the components from which the alloy is made, and coatings ob-
tained from a powder of the same chemical composition using plasma, which is generated by the plasma torch. It
was found that the average rate of destruction (Vs) of chromium, cobalt, tungsten is equal to 3.5; 0.72; 0.56 μm/h,
respectively, and Co-Cr-W alloy – 0.5 μm/h. After heat treatment of the Co-Cr-W alloy at a temperature of 1300 K
for 3.6 ks, the Vs value decreases to 0.28 μm/h. The plasmatron coating is destroyed at a speed of 0.13 μm/h, and
steel 15X11MF – 2.4 μm/h. Under the action of cavitation in a corrosive medium of a 3% aqueous solution of sodi-
um chloride Vs, steel 15Kh11MF and Co-Cr-W alloy increase almost 2 times.
INTRODUCTION
Increasing the life of equipment that operates in
conditions close to extreme, often associated with the
use of existing or developed resistant materials or coat-
ings based on them. Among such materials, a special
place is occupied by cobalt-based alloys known as stel-
lites. They have high wear resistance at normal and ele-
vated temperatures, thermal resistance, high heat re-
sistance and significant corrosion resistance in many
aggressive environments. The most used for practical
use, in particular to increase the life of dies, valves and
gate valves when regulating the flow of superheated
steam, valve seats of engines of heavy trucks are alloys
under the grades No. 6, No. 12; F; what have the name
stellites. The chemical composition, structure, and a
number of physicomechanical characteristics of these
alloys are presented in robots [1–4].
In [5–9], the effect of cavitation and water flows on
samples from various alloys of the Co-Cr-W, Ni-Cr-
W(Mo) type deposited using laser and arc methods was
studied. To create a cavitation zone, a method similar to
that described in ASTMG 32-10 [10] was used. As the
base on which the alloys are deposited, steels of the
SUS 303, 304, BS817M40, X9C2 type (GOST 5632)
were used. Specific in a number of works was the use of
the action of the cavitation zone on a sample through
which surface ultrasonic waves (20 kHz) passed.
Given the peculiarity of the task of increasing the
durability of the material in the conditions of its opera-
tion, there is a need to conduct appropriate studies on
the use of the Co-Cr-W alloy in each case.
In order to be able to use the alloy to protect the sur-
face of medium alloyed steels, in particular, 15Kh11MF
steel, which is widely used in turbine construction, we
studied the resistance of steel, alloy components and the
manufactured Co-Cr-W alloy and plasmatron coating of
the same composition. Under the action of cavitation
and high-speed vapor-droplet condensate.
MATERIALS AND METHODS RESEARCH
To produce the Co-Cr-W alloy, cobalt K2 grade
(GOST 123-2008), chromium obtained using the tech-
nology presented in [11], and tungsten using hot press-
ing technology [12] were used. Alloy samples were ob-
tained using the technology of the precision casting
method [1]. The coating was obtained using plasma,
which is generated in a plasmatron [13] using powder of
the EN1274: 2004-72 brand.
To obtain data on the destruction of samples under
the action of cavitation on their surface, their prelimi-
nary preparation was performed. Samples 10×16×5 mm
in size were cut out on an electric spark from a suitable
casting. After mechanical polishing, electro polishing
of, for example, chromium in phosphoric acid was car-
ried out for 0.15 ks at a voltage of 20 V and current den-
sity of 2 A/cm
2
. The surface roughness of the samples
was 0.025 μm.
A study of the effect of cavitation on the surface of
the samples was carried out at the MSV stand, the de-
scription of which is presented in [14]. The cavitation
zone was created in water using an ultrasonic concentra-
tor of an exponential profile, which is mechanically
connected to a magnetostrictive transducer, which is
electrically connected to an ultrasonic oscillation gener-
ator. Under the end of the concentrator, the amplitude of
surface oscillations of which was 302 μm, and a fre-
quency of 20 kHz, a cavitation zone was formed in
which the test sample was placed at a distance of
0.5 mm from the concentrator surface. The destruction
of the samples was recorded by weight loss. The accu-
racy of measuring weight loss is 0.015 mg. According
to measurements of the dependence of losses on the
time of the action of cavitation, the rate of destruction of
the samples was determined.
A study of vapor-droplet erosion was carried out at a
special bench [14], in which steam-water condensate
was supplied through a nozzle with an outlet diameter
of 1.3 mm at a pressure of 1.5 MPa. The velocity of the
droplets that collide with the surface of the sample was
440 m/s. Failure was also determined by measuring the
weight loss of the samples over a specific action time of
the condensate.
The study of electrochemical corrosion was carried
out using a potentiostat PI-50-1. Polarization curves
were obtained at a rate of change of potential of 1 mV/s.
Changed the potential three times in the forward and
reverse direction. For comparison, a chlorine-silver
electrode was used. The measurement results are con-
verted to a normal hydrogen electrode.
EXPERIMENTAL RESULTS
The values of destruction under the action of cavita-
tion of samples from materials that are part of the Co-
Cr-W alloy are shown in Fig. 1.
Fig. 1. Kinetic curves of fracture of samples under the
action of cavitation: 1 – steel 20X13; 2 – Cr, undo-ped;
3 – steel 15X11MF; 4 – Co; 5 – W, polycrystal
Using the kinetic curves of Fig. 1, the average frac-
ture rates (Vs) were calculated for the time interval of
cavitation action equal to 36 ks (10 h). Correspondingly,
for steel 20X13 the speed is about 4.87 μm/h, for Cr –
2.83 μm/h, steel 15X11MF – 2.4 μm/h, Co – 0.78 μm/h,
W – 0.56 μm/h It can be seen that the 20Kh13,
15Kh11MF steels used in turbine construction have a
value of destruction rates that are comparable to the
destruction of chromium, which is a significant part of
them. The specific nature of the destruction of undoped
and doped chromium is illustrated by micrographs of
the destruction zones shown in Fig. 2.
Fig. 2. Micrographs of the zone of destruction of chro-
mium (1-3) and the surface of the tungsten polycrystal
after the action of cavitation for 10 ks:
1 – Cr unalloyed; 2 – Cr doped with La, Ta, V;
3 – Cr doped with La, Fe; 4 – W. Magnification 400
Microphotographs (see Fig. 2, f. 1-3) show that the
alloying of chromium does not significantly change the
nature of its destruction. The fracture process is associ-
ated with the simultaneous propagation of cracks along
grain boundaries and in the body of grains between
structural defects. At the same time, tungsten is de-
stroyed at the location of inclusions (see Fig. 2, f. 4).
The results of investigations of the destruction of a
Co-Cr-W type alloy under the action of cavitation on
the samples without their preliminary heat treatment and
after it and upon the action of vapor – drop condensate
on the samples are shown in Fig. 3.
Fig. 3. Dependence of the average fracture depth
(l, mm) of Co-Cr-W (1, 2, 4), W (3, 5) samples, coatings
(6). Under the action of cavitation without heat treat-
ment (1, 6), after heat treatment (2, 3), after the action
of a vapor-droplet flow (4, 5).
A decrease in (4) by 2.5 times, (5) by 10 times
An analysis of the results presented in Fig. 3 shows
that after exposure of the Co-Cr-W alloy samples at a
temperature of 1300 K for one hour, the nature of the
destruction of the samples under the action of cavitation
does not change (cur. 1, 2). In this case, the fracture
rates Vп of the samples on the quasilinear parts of kinet-
ic curves 1 and 2 are close and equal to 2.5∙10
-1
μm/h,
and Vs are different and, accordingly, equal to 5∙10
-1
and
2.8∙10
-1
μm/h The difference between Vs and Vп indi-
cates the influence on the value of Vs of the higher sur-
face layers, which are destroyed first at the beginning of
cavitation. After heat treatment of the samples, the re-
sistance of the surface layers increases, and for the same
sample the difference between the values of Vs and Vп
does not exceed 15%.
Coatings under the action of cavitation are destroyed
much faster. The average rate of destruction is
1.36 μm/h, which is 2.7 times higher compared to the
Co-Cr-W sample without heat treatment and this is due
to the defective structure, in particular, column size and
precipitates along the boundaries between them (Fig. 4).
Under the action of a vapor-droplet flow for 43.2 ks
(12 hours) on Co-Cr-W alloy samples that are fixed to
the steel surface by soldering, their average fracture rate
reaches 5.2 μm/h. This is due to a significant increase in
the load on the surface compared with the effect of cavi-
tation. However, with different types of load, the kinetic
fracture curves are similar. The heat treatment of tung-
sten under the same conditions (soldering of the plates)
causes an increase in Vs to a value of 27.6 μm/h, which
is much more compared to the effect of cavitation.

Magnification 400
Under the action of cavitation on thermally untreated
samples in a 3% aqueous NaCl solution, the Vs value for
steel 15Kh11MF and Co-Cr-W alloy increases by
2 times. The results of measuring electrochemical corro-
sion in a 3% aqueous NaCl solution show that the alloy
corrodes starting from a potential of –0.17 V and has a
very narrow ( 0.1 V) zone of the passive state. The
corrosion resistance of the alloy is close to the corrosion
resistance of 15Kh11MF steel.
In the study of the coating, it was found that the po-
tential for the onset of corrosion is –0.1 V, and the in-
terval of the passive state reaches +0.3 V, which is
much larger compared to a bulk sample.
FINDINGS
1. For the time interval of the action of cavitation,
which corresponds to the quasilinear fragment of the
kinetic curve for the alloy, the erosion rates of its heat-
treated and untreated samples equalize and amount to
2.5 10
-1
μm/h.
2. Under the action of cavitation on the plasmatron
coating, which is similar in composition to the Co-Cr-W
alloy, its average fracture rate is 2 times lower than that
of 15Kh11MF steel, and coating can be used to protect
the steel surface.
3. Under the action of cavitation in a medium of a
3% aqueous NaCl solution on unprocessed bulk Co-Cr-
W samples, the average rate of their destruction increa-
ses by 2 times.
