Abstract: PURPOSE:To improve the partial performance of a sintered hard alloy by segregation, by cooling a mixture of powdered raw materials of sintered head alloys forming a bond phase in such a way that the bond structure changes partially while a temp. difference is held applied in the sintering members at the temp. at which the bond phase changes from a liquid phase to a solid phase in the course of the cooling in the sintering stage of said mixture. CONSTITUTION:In the case of using CO and Ni as metals of bond layers, a small amt. of Cr is added to the bond phase thereof, and the materials are subjected to the above-described cooling to cause segregation, whereby the layers where Cr is richer than the others are produced in the parts where corrosion resistance is required. As a result, the performance of the sintered hard alloy members is made better than those in the prior art. More specifically, metals and matallic oxides of the quantity smaller than that of the metals forming the bond phase are added mainly in the metals of the bond phase. As the metals for forming the bond layer, >=2 kinds of metals are used, and segregation is caused during cooling by varying the amts. of these metals to be added. The partial performance of the sintered hard alloy members is improved by said segregation.
