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 D₁₀ of the alloy powder is preferably 10 mum or more, and more preferably 15 mum or more. 50% particle size D₅₀ of the alloy powder is preferably 20 mum or more. The thermal spraying powder is suitable for use in forming a thermal spray coating through high-velocity flame spraying.
