METHOD FOR APPLYING METAL COATING ON THE SURFACE OF THE PART Russian patent published in 2022 - IPC C23C24/08 

FIELD: powder metallurgy.

SUBSTANCE: invention relates to powder metallurgy, in particular to methods for applying coatings from powder materials on the surface of parts. The method for applying a metal coating to the surface of a part includes pressing the surface of the counterbody to the surface to be treated with preliminary placement of the powder coating material between the surface to be treated and the counterbody and subsequent rotation of the workpiece relative to the counterbody, while the counterbody is made of a tungsten-based hard alloy, the coating material optionally contains a lubricant, and the counterbody and the workpiece with the powder coating material placed between them are preheated to a temperature of 150-350°C, after which the surface of the workpiece is pressed against the surface of the counterbody with a static load of 20-21 kgf and the workpiece is rotated relative to the counterbody with a rotational speed of 160- 170 rpm at a temperature of 150-350°С.

EFFECT: obtaining a coating that is uniform in thickness and has a low roughness.
