Spray coating method of performance mold using high temperature wear resistant spray alloy

摘要

The present invention relates to a spray coating method of a casting mold using a thermal spraying alloy having high toughness and high temperature wear resistance to form a high temperature wear resistant explosion spray coating layer to improve the life of the performance mold. It is characterized by using a thermal spray alloy in which a Co-based thermal spray alloy is mixed at 2: 8 to 5: 5.;According to the present invention, by spraying the coating by mixing the tungsten carbide and Co-based thermal spray alloy, high temperature wear resistance can be improved to extend the life of the playing mold.
