COMPLEX METHOD FOR INCREASE OF WEAR-RESISTANCE BEET-CUTTING KNIFES

摘要

A method for increase of wear-resistance of beet-cutting knifes comprises the quenching of cutting part of knife by high-frequency current on high-frequency plant and drawback in chamber electric furnace. The grains of tool material are first by ultra-crushed, for example, with powerful laser beam, and then microseparation meshes of obtained ultra-crushed grains are strengthened by refractory metals from vapors.
