ABSTRACT:
Surface-coated cemented carbide articles, in particular, cutting tools very excellent in wear resistance and heat resistance are made by an improved method according to the invention. This improved method comprises providing a 3-50 % by weight dispersion of fine powders of 20 microns or less containing 50 % or more of titanium carbide in a liquid consisting mainly of an organic solvent, applying a DC voltage of 10-500 volts to the surface of tungsten carbide base cemented carbides containing 4-30 % of a binder metal in said dispersion to thus cause electrophoretic deposition of the fine powders thereon, heating the coated surface at a temperature of 1260-1550 .degree.C in vacuum or in a reducing or inert atmosphere and thereby forming a coating layer consisting mainly of titanium carbide of 100 microns or less on the surface of the cemented carbides.
