This paper deals with the study of the influence of aspect ratio on coefficient of friction of lubricated reciprocating surfaces in boundary lubrication regime. Experiments were carried out on high frequency reciprocating wear testing machine. The operating conditions were set such that the boundary lubrication regime is achieved. Area density of 10% and dimple depth of 25μm maintained for all the samples. Results obtained in the tests showed that there exists an optimum value aspect ratio for which minimum value of friction coefficient is achieved. The trend of variation of friction coefficient can be explained by considering degree of interference of pressure generated at adjacent dimples and oil supply capabilities of surface textures. The value of coefficient of friction for untextured specimen was found to be lower than that of textured specimens.

Keywords: Laser surface texturing, Aspect ratio, Area density, Boundary lubrication
