THERMAL SPRAY COATING, METHOD FOR FORMING THERMAL SPRAY COATING, AND THERMAL SPRAY RAW MATERIAL POWDER

摘要

PROBLEM TO BE SOLVED: To provide a thermal spray coating which has excellent seizure resistance and wear resistance under the driving conditions of high rotation, high loads, and no lubrication, to provide a method for easily forming the thermal spray coating on the surface of a base material to be thermal-sprayed at a high speed, and to provide thermal spray raw material powder.;SOLUTION: The thermal spray coating consists of an Fe and/or Fe alloy structure containing an Mo sulfide, the solid solution thereof, an Fe-Mo sulfide, the solid solution thereof, an Fe sulfide, the solid solution thereof, an Fe-Mo intermettalic compound, the solid solution thereof, an Mo solid solution, an S solid solution, the oxide of Fe and Mo, and pores. In the method for thermally spraying thermal spray raw material powder on the surface of the base material to be thermal-sprayed to form a film thereon, Fe and/or Fe alloy powder containing 10 to 40 wt.% Mo and 1 to 5 wt.% S is used as the thermal spray raw material powder.;COPYRIGHT: (C)2003,JPO
