Abstract
The present study describes applicability of local surface deformation process consisted from burnishing and shot preening for surface finish on tribological properties of copper based alloy containing sulfide fine particles sintered on a steel plate. The shot peening was carried out with a developed apparatus possible to eject fine particle with a low flow rate. A roller burnishing process installed to a conventional lathe was applied to truncate after the peening process. A ring on disc type testing apparatus was used to evaluate tribological properties with a hardened carbon steel ring as a mating specimen with a mirror finished surface in lubricated condition. Results showed that the application of the truncation was effective to reduce the friction resistance at the initial stage of the friction experiment and it was found that the combined surface deformation process is available to fabricate the surface texture for tribological interface.
