Abstract

A technology of depositing wear resistant coatings by the method of thermochemical treatment by salt powders of refractory metals applied to hard-alloyed composites is proposed. The treatmeat process of hard-alloyed plates, allowing to increase the wear resistance of the hard-alloyed drilling tool bit is studied.
