  • Patent number: 4750667
    Abstract: A method whereby a base member having a surface on which a wear-resistant layer is formed and a mold member are disposed in opposing relation so as to form a gap between the surface of the base member and the surface of the mold member opposing the surface of the base member. Sintered hard substance grains of a hard substance powder such as material selected from carbides, nitrides and borides of metals belonging to groups IV, V and VI of the periodic table are filled in the afore-mentioned gap along the wear-resistant layer forming surface of the base member. A metal of self-melting alloy is then permeated into a filling-up layer of the sintered hard substance grains. The mold member is thereafter removed and the exposed surface is polished to obtain a fine wear-resistant layer on the base member.
