FIELD: process engineering.
SUBSTANCE: invention can be used in recovery and hardening of machine parts by electric-contact welding on. Metal strip side is processed to make micro relief on its surface with height corresponding to particle size of powder to be applied thereon. Metal powder monolayer, 5 to 50 mcm-thick, is applied on processed surface of aforesaid strip by gas dynamic spraying to produce bimetallic strip. Coat of part surface is produced by subsequent electric-contact weld-on of said bimetallic strip without melting its components.
EFFECT: higher efficiency.
