Ceramic adhesives were developed for bonding metal in the operational range 500° to 1000°F. When glassy‐bond adhesives were suitably prepared and properly applied to types 302 and 17–7 PH stainless‐steel specimens, shear strengths of the order of 2000 lb. per sq. in. were obtained at a test temperature of 800°F. and shear strengths of more than 800 lb. per sq. in. were obtained at 1000°F. Factors affecting adhesive strength included thermal‐expansion fit between ceramic adhesive and metal, metal or metallic oxide additions to the adhesive glass, and the use of metal screens of selected wire and mesh dimensions as carriers in the adhesive joint. The ceramic adhesive could be applied to a precipitation hardenable type of stainless steel during part of the precipitation hardening treatment, which included heating the metal for various times at temperatures up to 1750°F.
