HIGH SPEED FLAME SPRAYING METHOD

PROBLEM TO BE SOLVED: To provide a high speed flame spraying method capable of performing easily thermal-spraying coating having wear resistance and seizing resistance on the surface of the substrate to be thermal-sprayed at a high speed under the conditions of high speed rotation, high loads and nonlubrication. SOLUTION: This terminal spraying method is the one in which high speed flame is generated using a combustion gas, and terminal spraying raw material powder is thermal-sprayed on the surface of the material to be thermal-sprayed using the above high speed flame to form coating on the surface of the substrate to be thermal-sprayed. In this case, as the thermal spraying raw material powder, a powdery mixture contg. 90 to 75vol.% Cu base bronze alloy powder of 84 to 95wt.% Cu, 4 to 11wt.% Sn, 1 to 7wt.% Zn, and the balance impurities and 10 to 30vol.% Mo, MoO3 or polyester resin powder is used.
