Abstract

The effect of electromechanical treatment (EMT) on the structure and microhardness of a plasma coating prepared from austenite steel is investigated at 25 and 500°C. The EMT current is varied from 400 to 800 A, the treatment rate is 0.81–3.39 m/min, and the number of passes is from one to four. Consolidation of the coating is observed after EMT. Its microhardness increases from 1866 to 4618 MPa under EMT without heating of the sample and to 5814 MPa under EMT with heating to 500°C.
