This article deals with improving the wear resistance of multilayer coatings as a fundamental problem in metal surface treatment, strengthening elements of cutting tools, and ensuring the reliability of machine parts. It aims to evaluate the wear depth for multilayer coatings by the mass loss distribution in layers. The article’s primary purpose is to develop a mathematical method for assessing the value of wear for multilayer steel-based coatings. The study material is a multilayer coating applied to steel DIN C80W1. The research was performed using up-to-date laboratory equipment. Nitrogenchroming has been realized under overpressure in two successive stages: nitriding for 36 h at temperature 540 °C and chromizing during 4 h at temperature 1050 °C. The complex analysis included several options: X-ray phase analysis, local micro-X-ray spectral analysis, durometric analysis, and determination of wear resistance. These analyses showed that after nitrogenchroming, the three-layer protective coating from Cr23C6, Cr7C3, and Cr2N was formed on the steel surface. Spectral analysis indicated that the maximum amount of chromium 92.2% is in the first layer from Cr23C6. The maximum amount of carbon 8.9% characterizes the layer from Cr7C3. Nitrogen is concentrated mainly in the Cr2N layer, and its maximum amount is 9.4%. Additionally, it was determined that the minimum wear is typical for steel DIN C80W1 after nitrogenchroming. The weight loss of steel samples by 25 mg was obtained. This value differs by 3.6% from the results evaluated analytically using the developed mathematical model of wear of multilayer coatings after complex metallization of steel DIN C80W1. As a result, the impact of the loading mode on the wear intensity of steel was established. As the loading time increases, the friction coefficient of the coated samples decreases. Among the studied samples, plates from steel DIN C80W1 have the lowest friction coefficient after nitrogenchroming. Additionally, a linear dependence of the mass losses on the wearing time was obtained for carbide and nitride coatings. Finally, an increase in loading time leads to an increase in the wear intensity of steels after nitrogenchroming. The achieved scientific results are applicable in developing methods of chemical-thermal treatment, improving the wear resistance of multilayer coatings, and strengthening highly loaded machine parts and cutting tools.

One of the effective ways to improve the efficiency of cutting tools is the use of innovative types of multilayer coatings combining friction properties and high wear resistance. The object of study of this work was to investigate the influence of the composition of sublayer with anti-friction properties like component functional multilayer coatings on tool life. The data obtained in these studies were the basis for the development of the concept of functional multilayer coatings for cutting tools with programmable properties, providing an opportunity for each coating layer to perform a required function at a certain stage of tool wear. As used HSS substrate which is preliminarily subjected to ion nitriding by glow discharge and in addition alloyed gas-metal ions before coating deposition. The final step involved coating deposition process TiCrN using filtered cathodic vacuum arc deposition (FCVAD). Studies have shown that mixing the antifriction alloys which are widely used to improve friction properties allow to increase the tool life is not more than two times. This method of the tool life increase by reducing the shear strength of boundary adhesion between the tool and the work material does not seem to be the most effective for multilayered coatings under analysis, as for almost all studied anti-friction materials, the adhesion between the coating and the modified surface was rather low. This precludes their practical application due to technological reasons. Implantation the chemical elements can achieve much better results. Elements such as indium, silver and nitrogen increase tool life in 2 - 3 times for different cutting conditions (using dry cutting or cutting with cutting fluid). The obtained results can be considered as the most promising. Indium and silver are interactive with respect to Fe and may be used as lubricants in metal and promote a crushed chip forming at cutting using coating under the study. Ion surface modification of the tool with other studied elements demonstrates unstable or negative results that reduction in tool life or inability to provide good adhesion between the coating and substrate.

Alternated a-C/a-C:Cr coatings were made by DC magnetron sputtering from graphite and Cr target in an argon discharge. Mechanical and tribological properties were measured by indentation, scratch and pin-on-disc test. The critical scratch load of a-C/a-C:Cr multilayer coatings for total failure is approach 100 N. The friction coefficient remains within the range of 0.08-0.1 at loads between 10 and 40 N during a pin-on-disc wear test. The wear depth only reaches 0.6 μm after a one hour wear test. The greater compliance and fracture toughness of the a-C/a-C:Cr multilayer coatings allows greater strains or strain energy to be stored before coating failure, and hence significantly improves wear resistance

T This paper examines the abrasive and erosive wear of duplex multilayer TiN/TiCN and TiN/TiBN coatings deposited on quenched and tempered hot work tool steel grade X37CrMoV5-1. The coatings were produced by duplex method composed of a plasma nitriding and pulsed direct current (DC) plasma-assisted chemical-vapor deposition (PACVD). Measurements of the thickness of the deposited coatings were determined by calotest. Adhesion of the layers were determined by the Rockwell-C indentation test and the microhardness profile in a diffusion zone beneath the surface was determined by Vickers method (HV 0.05). Tests of abrasive wear resistance were carried out using "Dry Sand-Rubber Wheel” method. Test of erosion resistance of the base material and of duplex layers was carried out by exposing test samples to impact erosion of fine sand particles and determining the loss of mass after 60 minutes of wear. Worn surface were analysed by stereomicroscopy. The results show increasing wear resistance of duplex multilayer coatings of TiN/TiCN and TiN/TiBN in relation to plasma nitrided and uncoated steel (in the quenched in tempered condition).

The Difference

Carbon–chromium carbide–chromium multilayer coatings were deposited by utilizing reactive high-power impulse magnetron sputtering with alternating various ratios of ethyne and argon mixtures under a constant total deposition pressure, target pulse frequency, pulse duty cycle, average chromium target power, and total deposition time. Two different alternating gas mixture periods were applied to obtain films with different numbers of layers and lamination thicknesses. The results show that the reduction in the modulation period effectively affects the elastic modulus and the subsequent ratio of hardness to elastic modulus (H/E) of the whole coating, which helps adapt the elastic strain in the coating. This improves the adhesion strength and wear resistance of coatings at room temperature. However, with the increase in wear test temperature, the difference between the wear behaviors of two types of coatings becomes inconspicuous. Both types of coatings lose the wear resistance due to the decomposition of hydrocarbon and the oxidation of the chromium content in the films.
