Abstract

Improving the lubrication performance and reducing friction of tribological pairs have been important tasks for tribological researchers and lubrication engineers. Creating textures on the surfaces of tribological components by means of laser dimpling is one of approaches to improve surface lubrication properties. Two issues are addressed, i.e., the effect of surface deformation and the interaction among textures. The model system is used to investigate the lubrication and friction of textured and non-textured parallel surfaces in a range of applied load and sliding speed. The continuous convolution and fast Fourier Transform algorithm was used to accomplish surface infinite extension. The elasticity effect on texture performance was load dependent. The influence of cavitation on lubrication and friction was related to the ratio of dimple depth over dimple size. This is an abstract of a paper presented at the 2009 World Tribology Congress (Kyoto, Japan 9/6-11/2009).
