Abstract
The process of frictional processing of a plasma coating made of R6M5 steel on a cylindrical substrate has been developed and studied. Friction processing was carried out for 10–70 s by cyclic application of pressure of 30 MPa of two tools made of R18M5 steel on a coating rotating at a speed of 900 rpm, including additional movement of tools along the generatrix of the cylindrical substrate. With an increase in the friction treatment time, the coating surface temperature rises to 1202°C, which is sufficient for plastic deformation of the coating material. The coating microhardness after plasma spraying is 3.13 GPa; after friction treatment, it increases to 7.64 GPa. The large degree of deformation of the upper layers of coating under the action of tools determines the increase in the microhardness of the coating from the substrate to the free surface from 5.85 to 7.64 GPa.
期刊介绍：
Inorganic Materials: Applied Research contains translations of research articles devoted to applied aspects of inorganic materials. Best articles are selected from four Russian periodicals: Materialovedenie, Perspektivnye Materialy, Fizika i Khimiya Obrabotki Materialov, and Voprosy Materialovedeniya and translated into English. The journal reports recent achievements in materials science: physical and chemical bases of materials science; effects of synergism in composite materials; computer simulations; creation of new materials (including carbon-based materials and ceramics, semiconductors, superconductors, composite materials, polymers, materials for nuclear engineering, materials for aircraft and space engineering, materials for quantum electronics, materials for electronics and optoelectronics, materials for nuclear and thermonuclear power engineering, radiation-hardened materials, materials for use in medicine, etc.); analytical techniques; structure–property relationships; nanostructures and nanotechnologies; advanced technologies; use of hydrogen in structural materials; and economic and environmental issues. The journal also considers engineering issues of materials processing with plasma, high-gradient crystallization, laser technology, and ultrasonic technology. Currently the journal does not accept direct submissions, but submissions to one of the source journals is possible.
