HIGH SPEED THERMAL SPRAY COATING METHOD

摘要

In a thermal spray coating method, a high speed flame is produced by using a combustion gas and then thermal spray coating material powder is sprayed onto the surface 100 of the base material by using the high speed flame to form a coating 102 on the surface of the base material. As for the thermal spray coating material powder, a mixed powder is used. The mixed powder contains (A) 98-70% in volume of Cu based lead bronze alloy powder and (b) 2-30% in volume of Al powder or Al based alloy powder.
