Abstract:
A method of manufacturing a sliding part, comprising:an injection molding step of injection-molding a compacted member of a molding compound which is a mixture of a powdered, iron-based alloy material containing 10-20% Cr and more than 0.5% C, graphite carbon corresponding to an oxygen content of said material, and a binder;a degreasing step of heating said compacted member thus obtained by said injection molding step under a neutral atmospheric condition to remove substantially all of said binder from said compacted member; anda baking step of heating said compacted member under a vacuum condition of 0.1333 Pa or less from a room temperature up to 1000.degree. C. to reduce an oxygen content of the compacted member to 0.02% or less by the reaction of C+O.fwdarw.CO, and then heating said compacted member under an argon atmospheric condition of 133.3 to 3999 Pa for two hours after the temperature is increased up to 1250.degree. C.
