Titanium Carbide-Nickel Cermets: Processing and Joing
Abstract
Titanium carbide-nickel cermets can be sintered to have transverse rupture strengths over 250,000 pounds per square inch. To do so, four principal processing variables must be controlled: the powder must be as free as possible from oxygen and nitrogen; the powder must be milled in carbon tetrachloride and pressed without intermediate drying; sintering must be done in vacuo or possibly in an inert gas, but not in hydrogen; heating-up must be slow enough to allow thorough degassing. Joining titanium-carbide cermets to high-temperature alloys has been accomplished by vacuum diffusion, and gives a weld stronger than thee cermet. Fabrication of cermet articles of graded composition has been successfully accomplished by fragmentation-forming, i.e., cold forging the powder in a ductile envelope and subsequently sintering
