Kokoreva O.G. Increase of durability of heavy-duty machine parts of surfaces static-pulse treatment

Increase of durability of heavy-duty machine parts of surfaces static-pulse treatment

Kokoreva O.G.

Offered for practical use in production the new method of statiс-pulse hardening of hard loaded surfaces has a number of essential advantages in comparison with applied now. Distinctive feature of a method is the combination of static and dynamic processes of processing as a result of which necessary qualities of a blanket of a processed detail, and as necessary hardness and residual tension of compression are provided. This way of hardening is one of more effective, energy saving and easily realized in production. Static-pulsed hardening increases the number of controlled design, tuning, and technological factors that affect the result of hardening. As a result, the static-pulse processing provides reduced surface roughness, increased wear resistance and hardness of the surface layer by increasing the depth of hardening and changes in the microstructure of the metal. For the static-pulsed hardening is characterized by high performance and low cost compared with heat treatment and explosion.

Keywords: static-pulse treatment, hardening the surface, quality characteristics of the surface layer, reliability, durability.
