Claim 1
Independent Claim
120 words
THE METHOD OF PRODUCING COMPOSITE BODIES ADAPTED TO WITHSTAND CORROSION AT A HIGH TEMPERATURE COMPRISING COMPACTING SAID COMPOSITE BODIES FROM A REFRACTORY METAL CARBIDE POWDER SELECTED FROM A GROUP CONSISTING OF TITANIUM CARBIDE, MOLYBDENUM CARBIDE, TUNGSTEN CARBIDE AND ZIRCONIUM CARBIDE POWDER, CEMENTING THE SAID BODIES WITH A METAL SELECTED FROM A GROUP CONSISTING OF IRON, NICKEL AND COBALT, APPLYING TO THE SURFACE OF SAID CEMENTED BODIES AN INTERMEDIATE LAYER OF THE METALS USED FOR THE CEMENTING STEP, COVERING SAID INTERMEDIATE METAL LAYER WITH A SURFACE COATING OF A SUBSTANCE SELECTED FROM A GROUP COMPOSED OF CHROMIUM, ZIRCONIUM, ALUMINUM, SILICON AND THEIR HALIDES AND THERMALLY MERGING SAID INTERMEDIATE AND SAID SURFACE LAYERS INTO A BOND THEREBETWEEN AND WITH SAID CEMENTED BODY.
