METHOD OF TOOL AND MEMBER HARDENING Russian patent published in 1994 - IPC

Abstract RU 2019575 C1

FIELD: technology of wear-resistant coating applying. SUBSTANCE: to enhance wear-resistance of workable tools and members at tempering temperature below 300 C nitrides of refractory metals of IV-VI groups of periodic law system are used for applying of wear-resistant coating in combination with thermal working. Wear-resistant films are applied by known method on the articles at the base temperature 400-800 C before hardening, and the following hardening (cooling) is carried out in the inert gaseous medium. EFFECT: enhanced wear-resistance of workable tools and members. 2 cl
