Claim 1
Independent Claim
67 words
AN ARTICLE OF MANUFACTURE HAVING GOOD STRESS-RUPTURE STRENGTH AT HIGH TEMPERATURES, HIGH TEMPERATURE OXIDATION RESISTANCE, AND RESISTANCE TO CYCLIC FATIGUE FAILURE WHICH COMPRISES A CORE OF METAL SELECTED FROM THE GROUP CONSOSTING OF COLUMBIUM AND COLUMBIUM BASE ALLOYS, THE ARTICLE HAVING A DEFECT, OXIDATION, AND THERMAL-CYCLIC-FAILURE RESISTANT SURFACE ZONE CONSISTING ESSENTIALLY OF AT LEAST ONE COMPOUND SELECTED FROM THE GROUP CONSISTING OF COSI, COSI2, AMD MIXTURES THEREOF.
Claim 2
Dependent Claim
67 words

Claim 3
Dependent Claim
171 words
THE PROCESS OF COATING A FABRICATED BASE METAL WHICH PROCESS COMPRISES SURROUNDING A BASE METAL SELECTED FROM THE GROUP CONSISTING OF COLUMBIUM AND ALLOYS THEREOF WITH A POWDERED PACK OF A FINELY GROUND SOURCE OF COBALT AND A SMALL AMOUNT OF A VOLATILIZABLE AMMONIUM HALIDE SALT AS ACTIVE INGREDIENTS AND AN INERT FILLER, HEATING THE BASE METAL AND POWDERED PACK FOR A TIME PERIOD SUFFICIENT TO CAUSE VOLATILIZATION OF THE AMMONIUM HALIDE SALT AND TO PRODUCE DEPOSITION OF ELE: METAL COBALT ON THE SURFACE OF THE BASE METAL, THEN SURROUNDING THE COBALTIZED BASE METAL WITH A POWDERED PACK OF A FINELY GROUND SOURCE OF SILICON AND SMALL AMOUNT OF A VOLATILIZABLE HALIDE SALT AS ACTIVE INGREDIENTS AND AN INERT FILLER, HEATING THE BASE METAL FOR A TIME PERIOD SUMCIENT TO CAUSE VOLATILIZATION OF THE HALOGEN IN THE HALIDE SALT AND TO EFFECT THE CREATION OF AN EXTERIOR SURFACE LAYER ON THE BASE METAL COMPOSED PREDOMINANTLY OF AT LEAST ONE COMPOUND SELECTED FROM THE GROUP CONSISTING OF COSI2, COSI AND MIXTURES THEREOF.
