Processes for protecting products and tools during physical deformation of heavy metals and products so produced

Claim 1

IN A PROCESS OF PHYSICAL DEFORMATION OF A HEAVY METAL WORKPIECE BY A TOOL ACCOMPANIED BY ATTAINMENT OF AND ELEVATED TEMPERATURE BY THE WORKPIECE, THE IMPROVEMENT WHICH COMPRISES PROTECTING THE DEFORMED METAL PRODUCT FROM OXIDATION BY THE OXYGEN OF THE COOLING AIR AND PROTECTING THE TOOL FROM FRICTIONAL WEAR BY INTRODUCING A POWDER MIXTURE BETWEEN THE WORKPIECE AND THE TOOL AT THE ELEVATED TEMPERATURE AND BEFORE THE DEFORMATION PROCEDURE, SAID POWDER MIXTURE INCLUDING CRYSTALLINE COMPONENTS HAVING A SPACE-LATTICE CRYSTALLINE STRUCTURE, AT LEAST AN EFFECITVE PROPORTION OF SAID CRYSTALLINE COMPONENTS BEING OXIDES OF METALS HAVING AN AFFINITY FOR OXYGEN AT LEAST AS GREAT AS THE METAL BEING DEFORMED AND OXIDES OF THE METAL BEING DEFORMED, EACH OF SAID OXIDES HAVING A DEFINITE MELTING POINT, AT LEAST ONE OF THESE MELTING POINTS BEING ABOVE THE ELEVATED TEMPERATURE AND SAID POWDER MIXTURE INCLUDING COMPONENTS WHICH RENDER THE SAME PLASTICALLY DEFORMABLE AT THE ELEVATED TEMPERATURE, DEFORMING THE WORKPIECE, AND SIMULTANEOUSLY PLASTICALLY DEFORMING SAID POWDER MIXTURE SO THAT SAID POWDER MIXTURE DEFINES AN INTERFACIAL LUBRICATING LAYER BETWEEN THE WORKPIECE BEING DEFORMED AND THE TOOL, AND A LOOSELY ADHERING, READIAL REMOVABLE, UNIFORMLY DENSE, SPACE-LATTICE CRYSTALLINE ANTIOXIDATION COATING ON THE DEFORMED METAL PRODUCT.
