摘要：

PROBLEM TO BE SOLVED: To provide a method of manufacturing a silicon nitride wear

resistant member which has a predetermined electric resistance value (conductivity) in

addition to high strength-high toughness characteristics of original silicon nitride and is

excellent in especially sliding characteristics.

SOLUTION: The method of manufacturing a silicon nitride wear resistant member is

characterized as follows. A raw material mixed object, in which 12-28 mass% of silicon

carbide, 3-15 mass% in terms of a silicide of at least one kind selected from the group

consisting of carbides of Mo, W, Ta, and Nb, 2-10 mass% in terms of an oxide of a rare

earth element, 2-10 mass% in terms of an oxide of aluminum, and 5 mass% or less in

terms of an oxide of at least one kind selected from the group consisting of Ti, Hf, and Zr

are added to a silicon nitride powder having 1.0 μm or less of an average particle

diameter and including 1.7 mass% or less of oxygen and 90 mass% or more of α phase

type silicon nitride, is molded to make a molded body, the obtained molded body is

degreased, thereafter is sintered at a temperature of 1,650-1,850°C under a nonoxidizing

atmosphere, and thereby the carbide turns into a silicide.
