Abstract

In recent years, micro texture has been widely used in bearing and tool friction reduction. Laser machining is one of the most commonly used methods to process micro texture. Aiming at the recast layer and heat affected zone produced in laser texturing process, a water assisted laser processing technology was used to eliminate the adverse effects as much as possible. Taking 304 stainless steel as the research object, the effects of laser processing in the air and water assisted laser processing on the processing area and micro texture edge morphology were compared and analyzed. The influence of two machining methods on friction coefficient of lubrication micro texture friction pair was analyzed. The results show that the water assisted machining method reduces the heat affected zone and the cone angle of the edge. Moreover, water assisted laser processing avoids the generation of micro cracks which is very beneficial to the texture process of laser processing.
