Abstract
A method of providing sintered and diffused metal coatings of finely divided metallic material on a metal base, such as a steel strip or panel, by forming a molten film of one or more higher fatty acid amides having a carbon chain length from about 8 to 18 carbon atoms on a clean surface of the metal base which is preferably heated to a temperature above the melting point of the fatty acid amide film, applying uniformly on the molten amide film an amount of a finely divided metallic material, such as powdered Monel metal or nickel, in excess of that which settles into the film and is held thereby and removing the excess metal powder after the amide film has solidified, and heat treating the metal base having the coating of amide and metal powder thereon in a non-oxidizing reducing atmosphere at a temperature and for a period sufficient to effect bonding of said finely divided metallic material with each other and with said metal base to form a uniform firmly adherent metal coating. The metal base with the finely divided metallic material on the surface thereof can be compacted by rolling, either before or after heat treating, and thereafter annealed as required. The resulting coatings are porous coatings having a large surface area where no compacting is effected and are dense impervious coatings when compacted to effect a 60 percent reduction in the thickness of the base.
