Abstract:
A fine iron powder, being a carbonyl iron powder is electrolessly plated with an oxidatively resistant metallic coating. The coating is obtained from a bath containing nickel and copper salts. Oxidation resistance is improved at temperatures greater than 100. degree. C. Products containing these fine powders include liquids to provide increased oxidation resistance for coating a substrate, and articles formed by such powdered metals with or without other materials, such as ceramic or refractory materials.
