Filed: 2001-07-03
Abstract: PROBLEM TO BE SOLVED: To provide a method for producing multicomponent based ceramics powder or sintered compact which contains two or more kinds of metallic elements, N and C as constituting elements. SOLUTION: The powder of a first material containing at least two kinds of metallic elements selected from the groups consisting of Ti, Al, V, Nb, Zr, Hf, Mo, Ta, Cr and W is compacted into a compact (compacting stages S1 and S10). Next, the surface of the compact is heat-treated so as to be surround by a second material of metallic elements which are not contained in the first material as constituting elements in an atmosphere where N is present (a heat treatment stage S2). The porous sintered compact obtained thereby is ground (a grinding stage S3) to obtain multicomponent based ceramics powder.
