Abstract
When a chromium-iron-based alloy, preferably a chromium-iron-based alloy having a chromium content of about 60 to about 95 mass % is subjected to heat treatment at about 500 to about 1,300° C., and subsequently to grinding treatment by use of an impact mill, grindability of the chromium-iron-based alloy is improved, and running cost can be reduced. In addition, the resultant powdery thermal spraying material exhibits stable fluidity during spray coating, and thus a uniform coating can be formed.
