The paper considers one of the topical problems of the targeted control of the properties of the material of products in the zones under critical loads, which lead to their failure or loss of performance. The processes for the diffusion saturation of

The effect of different PVD coatings and their thickness on the tensile and cyclic elastoplastic strain resistance of Kh18N10T stainless steel and VT1 and VT20 titanium alloys was experimentally substantiated. The application of PVD coatings, also af

We present the results of the experimental investigations on the static and cyclic strength of titanium alloy VT20 with a TiN vacuum plasma coating. This coating has been found to increase the static strength characteristics and to reduce the plastic

To increase the life of cutting tools, it is proposed to form wear-resistant discontinuous coatings on their surface. In order to ensure cohesive strength of coating, coating crack spacing is taken as the size of discrete portion. It has been shown t

The authors suggest that the dimensions of a discrete section of a coating should be chosen on the basis of calculation of the critical crack spacing in cohesion cracking. This approach allows for residual stresses in the coating. The reliability of

Residual stresses in a plasma-vacuum-deposited titanium-nitride coating, which vary between –780 and –2800 MPa depending on the coating thickness, have been determined. It has been shown that deposition of a pure-chromium sublayer and substitutio

Measurements have been made on the wear resistance of ceramic cutters based on silicon nitride and bearing titanium nitride coating during the continuous machining of ShKh15 steel. The coatings were deposited by cathode sputtering. Use was made of co

A procedure is described and results are given for a study of the effect of coatings made of nitrides TiN and (CrTi)N on the fatigue strength σ−1 of sheet titanium VT1-0 with high-frequency (∼ 10 kHz) cyclic bending. Use of cantilever specimens
