Abstract

PURPOSE: To improve the abrasion resistance and defective resistance of a cermet tool by composing it of composition including a quantity of nitrogen, and providing a specified rigidity difference and toughness difference between its flank and its rake face.
CONSTITUTION: A molded body in the form of a tool is produced consisting of 70-95wt.% a right material phase component of an atomic ratio of 0.4-0.6 as expressed by nitrogen/(carbon+nitrogen) including Ti by 50-80wt.% as converted to carbide, nitride or carbonitride, and a group IVa metal by 10-40wt.% as converted to carbide, and 5-30wt.% a binder phase component. The molded body is installed in a vacuum furnace to be baked, and by introducing nitrogen gas at a specified timing of baking, a highly rigid layer having a rigidity gradient is formed in the surface of the sintered body. A flank A of a cermet tool has a layer 1 of a high rigidity, and by polishing this surface, the rigidity of a rake face A is reduced to expose an inner surface 2 of a high toughness. A rigidity difference and a toughness difference are thus produced between the flank A and the rake face B, thereby both the abrasion resistance and the defective resistance of the tool can be improved.
