Abstract

The microstructure and microhardness of a plasma-sprayed nickel coating on a cylindrical steel substrate were analyzed after friction machining with two high-speed steel tools moved linearly along the generatrix of a rotating cylindrical substrate. During friction machining, the coating surface and the working parts of the tools oxidize, which determines the mechanism of their interaction and limits adhesion between them. Increasing the coating surface temperature to 1500°C during thermoplastic machining allows for its deformation and compaction. An assessment of the energy-intensive process of friction machining of a nickel coating is proposed based on the power applied by the tools to the coating and the work performed on the coating area, taking into account cyclic compressive (up to 40 MPa) and shear (up to 10 MPa) loading for an exposure time not exceeding 50 s.
