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&deg; 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.

Method for producing spraying material

A method for preventing possible vapor explosion in the liquid comminuting process in metal refining comprising comparing pulse pressure generated in the course of liquid comminuting with a fixed reference pressure and adjusting the amount of molten metal thrown into water and the amount of water fed in accordance with the value of comparison.
