Paper Abstract

The paper considers the effect of CO2-laser fusing on wear resistance of a plasma coating made of self-fluxing powdered materials. The coefficient of mixing, depending on the depth of a melted layer and plasma coating thickness, is chosen as the characteristics of laser fusing. Wear resistance tests have shown that there is a specific range of mixing coefficient values within which wear resistance of fused plasma coatings is minimum. The data of micro-X-ray spectrum and X-ray spectrum analysis of the treating surface have shown that the increase of wear resistance is caused by the formation of strengthening phases that occurs at the given conditions of laser fusing.
