Abstract
A new method of ceramic-to-metal welding has been developed using a pressurized combustion reaction to form Mo—TiB2—Mo and Mo—TiC—Mo couples. Mixtures of Ti powder with B or C between Mo disks were electrically ignited under 3 GPa pressure. The exothermic reaction of the powders resulted in the formation of TiB2 and TiC and reaction with Mo at the metal interface. Weld strengths of the Mo—TiB2—Mo and Mo—TiC—Mo couples were 20—40 MPa and ∼ 10 MPa, respectively.
