Abstract:

Ceramic-to-metal bonding and ceramic adhesives for metals were studied. Successful ceramic-to-metal attachments were made by use of brazing alloys and by mechanical means. The attachment of metal-to-metal with ceramic adhesives was also attained. Small specimens of ceramics and metals were bonded and brazed together. The strength of these bonds was tested at room temperature, 1200 and 1500 F. Some of the brazed specimens exhibited a room temperature tensile strength of 11,000 psi and 5,000 psi when tested at a temperature of 1500 F. The majority of fractures at all temperatures on the brazed ceramic-tometal test specimens occurred at the ceramicmetallized interface or within the ceramic itself. Several ceramic adhesives were employed in efforts to bond various combinations of alumina, pyroceram, Rene41, Kovar A metal, RS-140 Ti, and 17-7 PH stainless steel. These specimens were tested at room temperature, 600, 800, and 1000 F. 17-7 PH stainless steel bonded with UI-1067-1A ceramic adhesive resulted in a shear strength of 1900 psi when tested at either room temperature or 1000 F.
