Abstract
Coatings of a powdered protective metallic material or refractory material and mixtures thereof are formed on a ferrous metal strip as a wet film dispersion in a resin binder composition of a synthetic organic resin and a volatile organic solvent compatible with said resin, and the coated strip is heated to effect curing said resin binder and forming a flexible non-tacky dry film. The metal strip having the cured dry film containing powdered protective metallic material can be subjected to varying heat treatments to provide a wide range of protective coatings having improved surface properties, including iron-protective metal diffusion alloy coatings, such as iron-aluminum diffusion alloy coatings having a surface concentration of aluminum between about 8 and 10 wt. percent aluminum, which have improved high temperature oxidation resistance after being severely strained during fabrication at room temperature.
