Verfahren zum Hochgeschwindigkeitsflammspritzen

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 by flame gun (1) onto a receiving surface (100) of a base material by using the high speed flame to form a coating (102) on the base material. As the thermal spray coating material powder, a mixed powder is used, which contains (A) 98-70% by volume of Cu based lead bronze alloy powder and (B) 2-30% by volume of A1 powder or A1 based alloy powder.
