description: The analysis of scientific and technical literature on the topic under study was carried out, on the basis of which the relevance of the work was substantiated and a comparative analysis was carried out, as well as the influence of the spraying distance on the hardness of the coatings was studied. The considered structure of coatings obtained from different spraying distances. The influence of the temperature of preliminary heating of the substrate on the residual stresses is studied, also in the coating witha thickness of 600 Î¼m, the dependence of the internal stresses on the depth is studied. The object of research is the coatings obtained by the method of high-speed gas-flame spraying. Coatings made of PRKh18N9 and WC-12Co powders were used to restore wornout compressor rings of the D-30F6 engine. The optimum spraying distance was found to be 177.8 mm. The optimum substrate temperature is 200 ÌC, the optimum coating thickness is 600 microns. The minimum values of internal stresses for the WC-12Co coating were 213 MPa, for the PRKH18N9 powder coating -521 MPa, the maximum hardness of the coating was WC-12Co -1201 HV, for PRKH18N9 -86 HRB.
