| description | The present study describes tribological properties of copper based porous alloy containing nano-sized sulfide particles. The porous alloy was fabricated with sintering on the steel plate using the developed powders consisted from Cu with dispersed sulfides. The micro structure of the alloys consisted from micro sized open pores and sintered particles. The measurement of tribological properties were carried out with a ring on disc testing apparatus with a steel ring as the mating specimen. First, comparison of friction behavior between the developed material and the lead-bronze alloy used as traditional materials for bearings are evaluated. As results, the friction coefficient of the developed material was stable and lower than that of the lead one and larger adhesion resulted in the higher friction resistance was found on the ring surface. In order to enhance porous structure on the reduction and stabilization of the friction resistance, graphite powder was penetrated into the pores by rubbing with the graphite rod. It was found that the further reduction of friction resistance was obtained. |
