AbstractAbstract
[en] The requirements for metal-cutting tools are increases. One of the most promising ways to solve the problem is the creation of new wear-resistant composite coatings for metal cutting tools. The physical and mechanical properties of coatings based on intermetallides of the Ti-Al system synthesized in the environmebt of oxygen by vacuum arc plasma are studied in this work. Microhardness, wear resistance, coefficient of friction, adhesion strength, scratch test of coating were studied on the obtained samples. Influence of the deposition conditions on the content of intermetallic compounds in the coating was established by X-ray diffraction methods. The results of investigations showed that the main physico-mechanical properties of coatings based on intermetallides of Ti-Al system synthesized in the environment of oxygen were increase compared to the coatings synthesized in the environment of argon or nitrogen.

AbstractAbstract
[en] This work is devoted to mathematical modeling of the process of deposition of composite coatings based on intermetallics of the Ti-Al system from vacuum-arc plasma, considering diffusion processes between alternating layers in order to predict the phase composition of the coating. The physical and chemical processes occurring during layer-by-layer deposition of multilayers coatings based on intermetallics of Ti-Al system by vacuum arc plasma in thin films were investigated. The processes occurring in the deposition of coatings based on intermetallic Ti-Al system by vacuum arc plasma were mathematically described. Diffusion processes were simulated using the finite element method. Diffusion processes occurring between layers of Ti and Al were modeled using Fick equations. Software based on mathematical model that allows to calculate the optimal deposition modes of coatings based on intermetallic Ti-Al system was developed. Influence of the deposition conditions on the content of intermetallic compounds in the coating was determined by X-ray diffraction methods. Results of mathematical model of deposition multilayer coatings considering diffusion processes were compared with experimental data. It is established that in the layer-by-layer deposition of titanium and aluminum, there are two mechanisms for the formation of intermetallic phases: due to diffusion processes and chemical reactions of samples running on the surface. A correlation between the percentage content of intermetallic phases in the coating and the diffusion processes between titanium and aluminum was established. (paper)

AbstractAbstract
[en] The effect of coatings deposited from a vacuum-arc plasma on the high-temperature corrosion resistance of martensitic steel in ultrafine-grained and coarse-grained state is studied. It is proved that coatings obtained from a vacuum-arc discharge plasma increase the high-temperature corrosion resistance of martensitic steel. The analysis of high-temperature corrosion resistance was carried out using the method of accelerated cyclic tests developed by the All-Russian Institute of Aviation Materials (paper)

AbstractAbstract
[en] Development and creation of intermetallic materials and nanostructured, amorphous materials, coatings with high physicochemical properties and technologies for their production are priority strategic directions for the development of materials and technologies. A mathematical model has been developed that makes it possible to determine the stoichiometric composition of the Ti-Al-O, Ti-Al-C, Ti-Al-N coatings under given treatment conditions. On the basis of the model, a software was created that allows calculating the ionic saturation current for each of the cathodes and the flow of metal ions per unit area per unit time at an arbitrary point of the vacuum chamber. Using the software product, it is possible to determine the stoichiometric composition of the Ti-Al-O, Ti-Al-C, Ti-Al-N system coatings, depending on the technological modes of their deposition from the vacuum-arc plasma.

AbstractAbstract
[en] In the work, the influence of technological parameters on the chemical composition of coatings alloyed with Cr was studied. The mechanical properties of alloyed coatings based on intermetallics of the Ti-Al system depending on the percentage contents of Cr are studied. For to determine the coefficients of friction and wear resistance were carried out Tribological tests by the Nanovea Tribometr equipment. Based on the results of the studies, the pilot lot of the slotting tool was processed and production tests were carried out. The results of the production tests showed an increase in tool life of 10 times compared to the original tool without coating. (paper)
