Abstract
PURPOSE: To provide the title member with superior toughness and wear resistance which takes the place of WC by coating a B-1 type hard phase on a sintered hard alloy consisting of Mo or Mo and W-based hexagonal monocarbide, iron group metal-based binder metal and a specific amt. of free carbon.
CONSTITUTION: A sintered hard alloy is formed consisting of hexagonal monocarbide based on MoC1-x or (Mo,W)C1-x (0≤x≤1), iron group metal-based binder metal, 0.01W0.50 wt% of free carbon and zero or more of a B-1 type solid soln. The alloy is then coated with a B-1 type solid soln. contg. Ti, Zr, Hf, V, Nb, Ta, Cr, Mo and W as metallic elements, and C, N and O as non-metallic elements. Esp. a B-1 type solid soln. contg. more than 50% of Ti out of the metallic elements and more than 50% of C out of the non-metallic elements shows desirable characteristics. It is effective to further coat the resulting B-1 type solid soln. film with a B-1 type solid soln. such as Al2O3 or ZrO2.
