STUDY AND USE OF CHROMIUM STEEL PLASMA HARDENING

摘要

Chromium steel (12% Cr) surface layer microhardness and microstructure after plasma hardening are studied. Friction tests show that plasma hardening increases chromium steel wear resistance by more than two orders of magnitude. Use of UDGZ-200 equipment makes it possible to perform hardening without deformation for steel 20×13 "races." Hardened race withstand standard acceptance tests.
