<p>PROBLEM TO BE SOLVED: To provide a high speed flame spraying method capable of easily thermal-spraying the surface of a substrate to be thermal-sprayed with coating having wear resistance, seizing resistance and pressure withstanding strength at a high speed under conditions of high speed rotation, high loads and nolubricant. SOLUTION: This thermal spraying method is the one in which high speed flame is generated by using a combustion gas, and the surface of a substrate 100 to be thermal-sprayed is thermal-sprayed with thermal spraying raw material powder by using the high speed flame to form coating 102 on the surface of the substrate to be thermal-sprayed. In this case, as the thermal spraying raw material powder, a powdery mixture contg. (A) Cu base lead-bronze alloy powder by 98 to 70vol.% and (B) Al powder or Al base alloy powder by 2 to 30vol.% is used.</p> |
