Manufacturing High Friction Surface by Laser Micro Texturing

Abstract

Laser micro texturing has the effect of increasing the coefficient of friction between metals by imparting fine surface irregularities. This paper describes some examples of micro texturing and outlines the effect of micro texturing. In the case of a titanium alloy textured with micro-texturing, the micro-patterns promoted titanium adhesion and increased the static coefficient of friction by a factor of 2.8. The reason for this increase in static friction can be attributed to the effective release of metal oxides, which have the effect of reducing friction. It is important to verify the effectiveness of the method in the presence of oily agents in the future.
