Abstract
PURPOSE: To inexpensively manufacture titled dies with large plastic deformability before breaking and with high stiffness at high temperature, by bonding (MoW)C- type crystal with iron-group metal on purpose to form a ring type cermet which is then sintered, and by filling the diamond (D) powder in this cermet, and by sintering D under a peculiar condition.
CONSTITUTION: In the carbide crystal represented by the form of (MoW)C, the ratio of atomic volumes of Mo and W is above 1:1; either one of Fe, Co, Ni, or their alloy is added to above carbide crystal as the bonding agent, and the material is sintered into a cermet. The amount of the bonding metal contained in this cermet is selected so as to be 5W30% of total volume of the cermet, on purpose to obtain the aim stiffness and toughness. The cermet is sintered at about 1200W1500°C within the environment of vacuum, inert gas, or reducing gas. In this previously sintered ring type cermet, the D powder is filled; and the cermet is hot pressed usually at above about 1200°C, by pressure above 45Kb; hereby, the D is sintered and also D is closely attached to the cermet.
