WEAR RESISTANT MATERIAL CONTAINING COMPOSITE MATERIAL CONSISTING OF NONCONDUCTIVE HARD MATERIAL POWDER AND METALLIC

摘要

PURPOSE:To obtain a wear resistant material to be melt-joined to the surface of a structure by heating a metal which can be melt-joined to the surface forming metal of the structure and two or more layers of a mixture of nonconductive hard material powder with metallic powder to a high temp. under pressure. CONSTITUTION:A metal which can be melt-joined to the surface forming metal of a structure and two or more layers of a mixture of nonconductive hard material powder with metallic powder are heated to a high temp. under pressure by directly supplying a strong electric current at a low voltage for a short time so that they are melt-bonded to each other.
