Thermal spraying powder, thermal spraying method and method for forming thermal spray coating

摘要

A thermal spraying powder contains a chromium-iron based alloy powder that includes carbon. The ratio of the mass of carbon in the alloy powder to the total mass of chromium and iron in the alloy powder is 2% or more. 10% particle size D 10 of the alloy powder is preferably 10 µm or more, and more preferably 15 µm or more. 50% particle size D 50 of the alloy powder is preferably 20 µm or more. The thermal spraying powder is suitable for use in forming a thermal spray coating through high-velocity flame spraying.
