Method for forming iron-based spray coating and iron-based spray coating coating member

摘要

A method for forming an iron sprayed coating on a substrate with droplets of a wire molten by an electric arc includes: a step of forming a first iron sprayed coating on the substrate, the wire for arc spraying being a first wire containing iron and 0.03 to 0.10% by mass of carbon and the compressed gas being inert gas; and a step of forming a second iron sprayed coating on the first iron sprayed coating, the wire for arc spraying being a second wire containing iron and 0.03 to 0.10% by mass of carbon and the compressed gas containing 10 to 21% by volume of oxygen gas.
