Abstract

Texturing of contact surface has a remarkable influence on their tribological properties. Various texturing techniques as machining, ion beam texturing, etching techniques and laser texturing are employed for preparation of micrometer-sized valleys. Modern modification of surface layers for friction application combines surface texturing and a filling of the textured layers by solid lubricant MoS2/WS2 or other compositions. In this work Pulsed Air Arc Treatment (PAAT) has been used in order to texture the surface layers. The textured surfaces obtained by PAAT have been filled by solid lubricant. The effect of the size and density of the dimples on adhesion, friction and wear life of burnished films were analyzed. It was shown that application of PAAT and filling of micro-reservoirs by solid lubricant particles provide high longevity under dry friction conditions. It was shown that the increasing the density of eroded spots led to increasing the wear life of solid lubricant films.
