It has been shown that ion nitriding of hard alloys in hydrogen-free medium leads to an increase of the average value of microhardness to 20.1 GPa and a rise of the breaking load by 15% at cantilevered bending. The turning of steels using nitrided in

The authors of the article discuss some feasible means of determining geometrical parameters of a discrete-type coating with a view to ensure adhesion strength of the substrate-coating composite. The stress-strain calculations are performed for an el

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

It has been shown that the stress concentration at the joint edges increases with rigidity of adhesive joints of pyroceramics. In view of the fact that the traditional methods are unsuitable for the reduction of stresses at the edges of joints of pyr

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

We propose a procedure and results of experimental determination of the dependence of adhesive strength of a ZrO2 plasma-sprayed heat-protective coating with NiCr sublayer on the value of the stationary temperature drop in it. The dependences of the

We establish the distribution of temperature formed under conditions of abrupt changes in the surface temperature near the adhesional contact between the base and the coating in a plate of infinite length made of molybdenum or niobium both sides of w

We studied the influence of plasma-deposited titanium-nitride coatings on the characteristics of short-term static strength of the matrix material. In the process of deposition of these coatings, we observed an increase in the conventional yield limi
