This article presents the results of wear tests at low climatic temperatures of modified gas-flame coatings with copper and cobalt spinels. Graphs of friction temperature changes at the initial stage of wear and along the entire friction path are shown. The results of mass wear of coatings and metal counterbodies are presented and analyzed.

This article presents the results of wear tests at low climatic temperatures of a modified coating made of flux-cored wire with aluminum oxide and a metal counterbody made of ShKh15 steel. The data of temperature changes, roughness parameters and friction surface profiles are shown. The results of comparative studies of the wear of a modified coating and a metal counterbody are presented and analyzed.
