Low-Speed Sliding Test of Cu-Ni-Sn Based Composite Materials Containing WS2

Low-speed sliding test of Cu-Ni-Sn based composite material contacts containing WS₂ Recently, the development of sliding contacts having low resistivity is low as well as have mechanical strength is required. In this study, sliding tests was carried out on 3 kinds of new composite material containing lamellar solid lubricant (QWS₂ etc.) in the Cu-Sn-Ni alloy. The results showed that excellent sliding characteristics was displayed by composite materials of Cu-Ni, 52 wt.% compared with other composite materials. In this study, contact resistance and coefficient of friction were examined, centering on composite materials of which 3 kinds of composition differed.
