METHOD OF STEEL ARTICLES WORKING Russian patent published in 2002 - IPC

Abstract RU 2194773 C2

FIELD: metallurgy and mechanical engineering, particularly, methods of working of articles from steel martensite base. SUBSTANCE: method includes plastic deformation of surface by sliding friction and hardening. Plastic deformation is effected at temperature of surface layer within interval from 195.8 100 C with sliding speed not higher 0.15 m/s. Hardening is carried out before plastic deformation. Besides, after plastic deformation of article, temperature is possible. EFFECT: higher hardness, heat stability and resistance to wear of steel articles. 2 cl, 3 tbl
