FIELD: metallurgy.
SUBSTANCE: prior to inductive hard-facing of the charge, the part is subjected to preliminary hardening to the depth of 0.3-0.6 mm. Used charge consists of the mix of 20-30% of boron carbide and 70-80% of flux. Said mix in depth of 0.8-1.4 mm is applied on the part. Said charge is fused by high-frequency current and cured at, at least, 1240°C for 50-70 s.
EFFECT: ruled out undesirable structures in the ply, hence, higher wear resistance.
