First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing an alloy coating, the method comprising: thermally spraying a Ni—Fe base alloy powder comprising Cr of 15% by mass or more and 35% by mass or less, Fe of 10% by mass or more and 50% by mass or less, Mo of 0% by mass or more and 5% by mass or less, Si of 0.3% by mass or more and 2% by mass or less, C of 0.3% by mass or more and 0.9% by mass or less, and B of 4% by mass or more and 7% by mass or less, and a balance of Ni and incidental impurities to form the alloy coating; and then subjecting the alloy coating to a remelting treatment at a temperature range from more than 1080° C. to 1140° C. or less using high-frequency induction heating to metallurgically bond the alloy coating with a substrate and lower the porosity in the alloy coating to generate nodular precipitates on an alloy coating surface with a coverage of 30% or more and less than 100%.
