CORROSION-RESISTANT ALLOY COATING FILM FOR METAL MATERIALS AND METHOD FOR FORMING SAME

摘要

[Problems] To provide a highly corrosion-resistant alloy coating film on the surface of a metallic material by a low-cost and mass-producible simple formation method [Means for solving] A corrosion-resistant alloy coating film formed on the surface of a metallic material, the film containing Ni, Cr, and Si as essential constituents, further where the content ratio of Cr is 1 to 50 wt%, the content ratio of Si is 0.1 to 30 wt%, and the film has a thickness of 0.1 to 1000 µm
