Why is it important?
Cu-FeS composites without lead were prepared by power metallurgy process. The friction and wear properties were examined on a testing machine under dry sliding conditions with and without oil immersion.
Perspectives
Results showed that both the frictional coefficient and the wear volumes decreased with increased FeS content in the composite under dry sliding conditions. In the condition of dry friction without oil immersion, the FeS solid lubricating film formed and played a role of antifriction and adhesion resistance. Under the dry friction condition with oil immersion, the lubricant oil stored in the porous FeS layer precipitated to the surface to form the oil film, which could work together to achieve a liquid090009solid synergistic lubrication with the FeS transfer film.
