the effect of volume percentage of graphite coated by electroless method on the electrical resistance of silver graphite composite

The current research is investigating the effect of weight percentage of coated graphite on the electrical resistance of silver-graphite composites (contact material) with the aim of creating a metal-metal bond at the interface of two phases. therefore, the electroless method was used to deposit silver on graphite, and finally, the desired amounts coated with graphite powder were ground with pure silver. after ball milling, the powders were sintered through the sps process and subjected to electrical resistance testing. improvement of electrical resistance properties was also observed in higher percentages of graphite that the specific electrical resistance will remain below 1*10-7 µm, according to the b664-18 standard.
