Patent ID: 8668959

Claim:
A method of imparting high-temperature, degradation resistance to a metallic component comprising: applying a metal slurry comprising solvent, binder, and metal particles of a Co-based alloy comprising between about 0.05 and about 0.5 wt % B, between about 5 and about 20 wt % Cr, between about 22 and 32 wt % Mo, between 1 and about 4 wt % Si, and balance Co to a surface of the metallic component, and wherein the metallic component has a body of a material selected from the group consisting of carbon steel, stainless steel, and alloy steel; and heating to remove the solvent and binder and to sinter the Co-based alloy to form a substantially continuous Co-based alloy coating on the surface of the metallic component, wherein the Co-based alloy coating has a microstructure characterized by a generally non-dendritic, irregularly spherical, nodular intermetallic phase.
