Abstract
This article presents the results of determining the adhesion strength of a composite coating with Kh12MF steel substrate deposited by plasma spraying method using a domestic installation UPU-3D. As a composite powder, a mechanical mixture of powders PR-NX17SR4 and tungsten carbide clad with nickel in various percentages is used. The sprayed samples are subjected to heat treatment at a temperature of 1025 °C. The adhesion strength is determined by the adhesive method according to GOST 9.304—87. It is found that the highest value of adhesion strength is achieved when using a powder containing equal parts of PR-NX17SR4 and clad tungsten carbide in its composition. It has been also found that heat treatment significantly of the powder to the substrate.
