Abstract

PURPOSE:To improve resistance against abrasion and heat, by incorporating metal nitride and carbide nitride with high resistivity against thermal cracking and tenacity. CONSTITUTION:A tip is made of super-hard alloy composed of 0.5-50% by weight of one or more metals selected from a group consisting of the nitrides and carbides/ nitrides of one or more sorts of metals of the 4a, 5a, and 6a groups in the Periodic Table, 2-20% by weight of Co or Co base alloy, and the rest of tungsten carbide and inevitable impurities. The tip includes a soft surface layer whose vickers hardness is 5-50% lower than that of an inner layer 5-100mum deep from the surface of the tip.
