... kW resistance welding equipment, with water-cooled copper electrodes, has been successfully used to spot weld thin TMCs. Fabricators often use conventional titanium (e.g., Ti-6Al-4V) to set the initial welding parameters. As with any spot welding operation, it is important to thoroughly clean...

... the precipitate into a copper coating. The idea is to sinter to 80% density. Then, copper infiltration is used to fill the pores, with the copper coating acting to siphon the copper into the structure. The resulting component is an excellent thermal heat-dissipation device used in electronics. A similar idea...
