Effect of plasma treatment parameters on the structure and properties of type 60G steel

Abstract

Successful use of plasma hardening technology requires a search for optimum plasma treatment methods, especially when there is a change in the chemical composition of the metal in the products. In order to study the impact of the chemical composition of steel on the structure and properties after plasma hardening, various steel alloying options were selected with respect to concentration of major elements affecting phase transitions upon cooling. In wheel steel, these elements are carbon, manganese, chromium, and others. This paper describes the results of metallographic studies and mechanical tests.
