Claim 1
Independent Claim
166 words
IN A METHOD FOR PRODUCING A STRONGLY COATED THERMAL ELEMENT BY CONTACTING A DUCTILE HEAT RESISTANT METAL COATING MATERIAL WITH A COMPOSITE BASE MATERIAL COMPRISING SUBSTANTIALLY REFRACTORY METAL COMPOUND GRAINS SELECTED FROM THE GROUP CONSISTING OF CARBIDES, BORIDES, NITRIDES AND SILICIDES OF TITANIUM, ZIRCONIUM, CHROMIUM, MOLYBDENUM, TUNGSTEN, VANADIUM, COLUMBIUM AND TANTALUM, AND MIXTURES THEREOF, DISTRIBUTED THROUGH A MATRIX OF A HEAT RESISTANT BINDER METAL CONTAINING A LOW MELTING PHASE BASED ON THE BINDER METAL AND THE REFRACTORY METAL COMPOUND AND WHEREIN THE COATING AND COMPOSITE MATERIALS IN CONTACT WITH EACH OTHER ARE HEATED TO AN ELEVATED TEMPERATURE TO EFFECT THE BONDING OF ONE WITH THE OTHER, THE IMPROVEMENT WHICH COMPRISES MAINTAINING THE SOLIDUS TEMPERATURE OF AT LEAST ONE OF THE MATERIALS NOT HIGHER THAN 100*C. BELOW ITS LOWEST MELTING POINT FOR A TIME NOT EXCEEDING 120 MINUTES, SHORTER TIMES BEING EMPLOYED WHEN THE MELTING POINTS OF THE MATERIALS BEING JOINED ARE CLOSE TOGETHER, WHEREBY EXCESSIVE DIFFUSION OF EMBRITTLING AGENTS INTO THE COATING MATERIAL IS GREATLY INHIBITED.
