Diffusion welding and soldering of metal wire to graphite and graphitized viscose
A method has been developed for soldering graphite fiber to chromel, kopel, and chromel-alumel wires by tin solder, with premetallization of the fiber at the site of the joint with an alloy containing 10% copper, 18% titanium, and 72% nickel.
A method has been developed for soldering molybdenum, tungsten, and tungsten-rhenium wires in vacuum to graphite, using an NiMo alloy (47 wt.% Mo) as solder.
These methods of bonding metal wires to graphite and graphite fiber give a strong joint and ensure a good electrical contact and minimal embrittlement of the metals (molybdenum and tungsten).
