Zusammenfassung:Surface texturing has been recognized as an effective means to improve the tribological performances of sliding surfaces. Different densities of micro dimples were fabricated on Oxygen-Free High Conductivity (OFHC) copper by laser peen texturing (LPT). The tribological characteristics of the samples were tested by surface-to-surface sliding contact experiments under constant sliding velocity and linearly increased normal load. The effects of texture density on the friction coefficient, failure time and load carrying capacity were investigated. It was found that in comparison with smooth surfaces, textured surfaces help to reduce the friction coefficient, prolong the failure time and improve the load carrying capacity. Results also suggested that there might exit an optimum texture density with which the surface exhibits better tribological behavior than those with higher and lower texture densities.
