Characteristic of Remelting Ni60 Alloy Coating by High Temperature Resistance Electric Furnace

摘要

This paper reports on a new clad technology that is protective coating cladding. The method is that the Ni60 alloy was prepared on 0.45%C steel and high temperature powder paste brushed on the outside. Then the sample after being dried was heated in the high temperature resistance electric furnace. The Ni60 alloy powder on the substrate steel was melted at the appropriate temperature, and a uniform, adherent and non-dilution clad coating was obtained after optimizing the cladding parameters. The coating microstructures, compositions and microhardness were analyzed by OPM, XRD, EPMA, and microhardness testing. The experimental results show that the protective coating cladding is an efficient and economic method in cladding technologies.
