Observational analysis details friction treatment effects on microstructure and microhardness of plasma nickel coating, suggesting oxidation plays a critical role.
Made the analysis of a microstructure and microhardness of a plasma nickel coating on a cylindrical steel substrate after frictional processing by two tools from quick cutting steel. The substrate with a coating rotated, and tools linearly moved along the forming cylindrical substrate. At frictional processing a surface of a coating and end faces of tools are oxidized that defines the mechanism of their interaction with restriction of adhesion between them. Temperature increase of a surface of a coating up to 1500 °C allows to deform them and to condense. Suggested to estimate power process of frictional processing of a nickel coating in size of the power enclosed by tools to a coating to the work performed on the area of a coating taking into account cyclic loadings of compression up to 40 MPa and shift up to 10 MPa within 50 seconds.
