Методи поверхневого зміцнення деталей машин

Abstract

The surface hardening is based on underpinning of high concentration energy to local volume of surface layers of parts which is followed by structural and phase transmutation of metal. Friction working is one of hardening methods. It is accomplished by high speed friction to harden surfaces of parts. The specific structural stress state is formed in surface layer of parts. The hardness, toughness, durability underwear of surface layers and other characteristics are increased. This manufacturing process gives the local hardening of machine parts.
