Inventor: SHIMA NOBUHIKO
IPC: C22C1/05
Filed: 1986-06-30
Abstract: PURPOSE:To improve the pitting resistance of a sintered hard alloy consisting of WC as a dispersed phase forming component and one or more kinds of iron group metals as binding phase forming components in a specified ratio by very rapidly cooling the sintered hard alloy at a prescribed cooling rate after sintering. CONSTITUTION:A sintered hard alloy consisting of 50-95wt% WC as a dispersed phase forming component and the balance one or more kinds of iron group metals as binding phase forming components is produced by sintering. In a cooling stage after the sintering, the sintered hard alloy is very rapidly cooled from the sintering temp. at >=100 deg.C/min cooling rate. By this method, the deposition of WC during cooling is inhibited and the rate of contact of WC can be remarkably reduced, so the toughness and pitting resistance of the sintered hard alloy can be improved.
