Effect of Electrolytic-Plasma Hardening on the Microstructure and Tribological Properties of Low-Alloy Steels

Effect of Electrolytic-Plasma Hardening on the Microstructure and Tribological Properties of Low-Alloy Steels

This study investigates the effect of electrolytic-plasma hardening (EPH) on the structure, phase composition, and tribological properties of the low-alloy steels 20Cr2Ni4A and 37Cr4 (1.7034) (EN). Hardening was carried out at a voltage of 320 V for 7 s in an aqueous solution containing 20% soda ash...
