FIELD: process engineering.
SUBSTANCE: invention can be used for surface hardening of tillage machine working tools, particularly, plough centre hoes. Hard alloy mix arranged at hoe blank edge rear side is heated by inductor to fusion point simultaneous heating of said blank. Heated blank with fused hard alloy mix is placed in the mould forming tooling for hot deformation with simultaneous blank edge hardening and stretching in one press pass proceeding from the condition that hardness of built-up metal is 25-32 HRC units higher than that of parent metal of said tool.
EFFECT: higher precision of geometrical sizes.
