Zusammenfassung:PURPOSE:To improve the wear and corrosion resistances of the titled member made of a sintered alloy consisting of a prescribed amount of a hard phase contg. Cr carbide and solubilized carbide of Cr and W and a binding phase by incorporating Cr, Mo or W into the binding phase in the form of a solid soln. CONSTITUTION:The titled member is made of a sintered alloy consisting of 1- 30wt% hard phase and the balance binding phase. The hard phase consists of Cr carbide and solubilized carbide of Cr and W. The binding phase contains 5- 30wt% one or more among Cr, Mo and W in one or more kinds of iron group metals in the form of a solid soln.
