Method of producing a rolling contact member
A method of producing a rolling contact member comprising the steps of:preparing a powdery source material that contains as a main component a ²-sialon represented by a compositional formula of Si6-ZAlZOZN8-Z and satisfying 0.1 ¤ z ¤ 3.5 and has a remainder formed of an impurity; shaping said powdery source material generally into a geometry of said rolling contact member and sintering said shaped body at a pressure equal to or smaller than 1 MPa, further comprising the steps of forming a surface of said shaped body before sintering said shaped body, and working a surface of said shaped body sintered, to remove a portion including said surface, the step of working removing said shaped body by a thickness equal to or smaller than 150 µm.
