INTRODUCTION
Wrapping machine of MC1DT-T type (MC
Automations) is used in food industry for cutting of
packaging film and further wrapping of sweets. The
operational properties of such devices, on large extent,
depend on the durability of the blade tool used in this
machine. During operation, damageability and
destruction of such tools took place. In so doing, a
comprehensive complex control of cutting-tool
properties and wear behavior during operation as well as
utilization of various hardening methods is a key
solution for preventing degradation of tools surface
increasing their service-life.
The physical and mechanical characteristics of the
surface working layer can be improved by chemical-
thermal treatment or application of wear-resistant
coatings using various PVD methods [2, 3]. Standard
heat treatment and quenching in oil with heating up to
960…980°C and subsequent low tempering at a
temperature of 180°C is used to partially relieve the
stresses formed during quenching and achieve high
hardness (at least 62 HRC) [1]. The hardness level can
be increased correcting the tempering temperature
(Fig. 1).
The research was performed in two stages: in the
first stage, the cutting knives were characterized
regarding their wear behavior, degradation mechanism,
chemical composition and structure using optical
microscopy, scanning electron microscopy (SEM),
X-ray diffraction (XRD), and nanoidentation,
respectively. During the second stage, ZrN coatings
were applied on such knives by means of vacuum-arc
evaporation with RF discharge and industrial tests were
carried out.

temperature
1. EXPERIMENTAL SETUP
Packaging knive made of X205Cr12KU high-alloy
steel has four cutting edges and turns over during
operation in order to use a sharper blade. Tool
sharpening is carried out after all four corners cease to
perform their cutting functions. Sharpness of the edge is
restored by rectifying two end planes of the tool.
To improve wear resistance and durability of such
knives, ZrN coatings were applied by vacuum arc
method with the use of high-frequency discharge (RF)
in the Bulat-6 type installation. Bias potential was
applied to the substrate from RF generator, which
produced impulses of oscillations at 5 MHz frequency.
Chemically pure zirconium (99.999) was used as a
cathode material. Nitrogen at a purity of 99.999 % was
used as an active gas. The surface cleaning in RF
discharge took place in argon plasma in order to make
substrate degreasing and remove impurities for 15 min
(Ubias = -1000 V, P(Ar) = 6 × 10-1 Pa). In order to
improve the coating adhesion, a thin 20 nm Zr buffer

layer was deposited before the nitride coatings.
Application parameters: Iarc = 110 А, URF
bias = -200 V,
base pressure P = 5×10-4 Pa. Time 25 min. The
thickness of coating was 4.4 μm. Deposition rate was
34 µm/h.
The study of the structure and chemical
composition was carried out using scanning electron
microscope JEOL JSM-6390LV at an accelerating
voltage of 10 kV equipped with EDS analyzer. X-ray
diffraction (XRD) studies were performed using
DRON-3M device, under Cu-Kα radiation. To analyze
the mechanical properties the Nanoindentor G200 and
the CSM method with automatic continuous recording
of the loading and unloading diagrams were used. The
amount of the carbide phase, as well as its distribution
on the surface were calculated using the computer
program Thixomet Pro.
2. RESULTS AND DISCUSSION
2.1. TOOL DEGRADATION MECHANISM
Fractured tool surface with fatigue wear resulted
from cyclic loads is shown in Fig. 2. Some micro pores
and microcrack were found to form during plastic
deformation and destruction of the carbide phase.

Fig. 2. Tool surface with fatigue wear resulted from
cyclic loads
The origin and further spread of microcracks began
from the edge of the working surface (Fig. 3). In
addition, micropores and nonmetallic inclusions are
locally found in the tool metal structure, which serve as
stress concentrators. All this contributed to futher
destruction of the tool (see Fig. 2).
According to XRD data, the main matrix of metal
knife consists of martensitic tempering phase and Cr7C3
special carbide phase.
Fig. 3. SEM image of the tool working layer with
microcracks
Analysis of the optical microscopy images from
individual zones of the tool with the help of the
Thixomet Pro program revealed that the number of
doped special carbides was different. A decrease of
special carbides in the working surface layer by 43.7 %
contributed to a significant decrease in the wear
resistance of the tool. This is determined by the
degradation of the material during operation. The total
amount of carbides was 14.4 % of the metal matrix in
the middle of the tool, and at the edge of the working
surface it did not exceed 8.15 %.
It was established that tool degradation mechanism
is preceded by the following stages: destruction of
carbides and diffusion of their components,
fragmentation of small carbides during deformation,
aligning them in chains and along grain boundaries, the
appearance of a more decarburized light zone along the
working surface during operation, and the formation of
cracks. In the subsequent operation, chains of small
carbides are located at an angle of 45° (corresponds to
the effect of compressive stresses). The working surface
is destroyed from the formed cracks.
The nanohardness of special carbides was 2.2 times
higher than that of the base metal of the matrix. The
hardness of the steel matrix was 9.19 GPa. The data
spread obtained from the results of the 7 measurements
was 4.35 %. The average nanohardness of special
carbides reached 20.33 GPa. Spec-carbides have higher
elastic properties. The modulus of elasticity of the steel
matrix is 246.4 GPa with the data spread 5.0 %. The
average value of elastic modulus for special carbides
was 275.87 GPa with a minimum data spread of of
1.6 %.

Fig. 5. XRD spectra from ZrN coating
Typical XRD pattern of ZrN coating obtained in RF
regime is presented in Fig. 5. All angels of diffraction
peacks with (111), (222), and (220) main reflections
were indexed as ZrN phase with a crystal structure of
B1 NaCl cubic lattice type (according to JCPDS 35-
0753, a = 0.4577 nm lattice constant). XRD data
revealed the formation of finecrystalline structure with
the grain size of 20 nm.
From Fig. 6, we can conclude that components Zr
and N, forming superdispersed nitrides ZrN, distribute
evenly across the surface. Results of EDS analysis are
shown in Table.

On the basis of the obtained load/unload diagrams,
the elastic recovery of the ZrN coating was evaluated
(Fig. 7). The measurements were carried out at a load of
up to 80 mN and the penetration depth of the indenter of
523 nm. The elastic recovery reached 36.8%.
It was established that all physical and mechanical
characteristics of the ZrN coating are significantly
higher in comparison with the initial metal tool (Fig. 8).
The maximum nanohardness of the ZrN coating reached
32.05 GPa, which is 3.4 times higher than the knife
matrix and 57.65 % higher than that of the base metal
special carbides. The high level of nanohardness of the
ZrN coating made it possible to increase the wear
resistance of the working surface layer and to increase
the time between the repair periods by re-grinding.

The average value of the elastic modulus for the ZrN
was 320.81 GPa. The spread of the data obtained does
not exceed 10.04 %.
The shear modulus G was calculated using the
formula:
) + (1 *

G m=

Where, E is elastic modulus (GPa), µ is Poisson's ratio.
The maximum resistance to shear stress during
operation for the ZrN coating reached 210.77 GPa. This
allowed stabilizing the working surface layer of the tool
during deformation and reducing the propensity to
develop diffusion processes.
The tensile strength of the working surface was
calculated using the equation:
в max = 0.333 *Н ,s (2)
ISSN 1562-6016. ВАНТ. 2018. №6(118) 303
where Hmax is the maximal hardness (GPa).
As a result of the theoretical calculation it is
established that the maximum tensile strength that is
capable of withstanding the ZrN coating comprised
10.67 GPa, above which the probability of its
destruction may increase.
The ability of the material to resist the elastic
deformation was evaluated by the H/E ratio. It was
found that the maximum elastic fracture deformation for
the ZrN coating does not exceed 0.095.
The plastic deformation resistance coefficient was
calculated as the ratio H3/E*2, where E*2 is effective
Young's modulus, which was calculated from the ratio:

The coefficient of resistance to plastic deformation
H3/E*2 for the ZrN coating reached 0.254.
Industrial test results showed that the hardening of
the knives by the ZrN coating according to the proposed
technology provides a 3 times increase in durability
during operation.
CONCLUSIONS
The wear behavior of packaging knives made from
high-alloy steel of X205Cr12KU type used in wrapping
machines of MC1DT-T type (MC Automations, Italy)
has been investigated. ZrN coating was applied on such
a knife by vacuum arc deposition with the use of high-
frequency discharge. XRD data revealed the formation
the formation of stoichiometric ZrN phase of cubic
modification with average grain size of 20 nm. The
maximum nanohardness of the ZrN coating reached
32.05 GPa. The modulus of elasticity reaches
320.81 GPa, and the tensile strength was 10.67 GPa.
The application of such a coating provides an increase
in mechanical properties, allows stabilizing the working
surface layer under deformation, preventing the carbide
phase from being crushed and the development of
diffusion processes. The conducted tests showed that
hardening of knives with ZrN coating provides an
increase in wear resistance by 3 times.
