摘要:
A thermal spraying powder contains 30 to 50% by mass of chromium carbide with the remainder being an alloy containing chromium, aluminum, yttrium, and at least one of cobalt and nickel. The thermal spraying powder has an average particle size of 20 to 60 μm. The thermal spraying powder may contain 20% by mass or less of yttrium oxide in place of a part of the alloy. A thermal spray coating obtained by thermal spraying of the thermal spraying powder, particularly, a thermal spray coating obtained by high-velocity flame spraying of the thermal spraying powder is suitable for the purpose of a hearth roll.

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 μm or more, and more preferably 15 μm or more. 50% particle size D50 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.
