Title: METHOD OF FORMING A SPRAYED IRON COATING AND COATED MEMBER
Abstract:
A method for forming an iron sprayed coating (23) on a substrate (21) with droplets of a wire molten by an electric arc includes: a step of forming a first iron sprayed coating (24) 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 (25) on the first iron sprayed coating (24), 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.
