Laser Surface Texturing and Techniques to Improve the Tribological Properties of Materials
Öz
Surface texturing, a technological method in the last decade, is one of the surface modification techniques that change the surface texture to improve the tribological properties of materials. On the material surface, high wear resistance, reduction of friction coefficient and improvement of lubrication conditions are provided. Recently, various surface texturing processes have been developed. One of these, Laser Surface Texturing (LST), is the most developed among them. Different texture densities, size and depth, feature alignment and shape changes in the LST process have been the subject of theoretical and experimental researches. The coefficient of friction manipulated by the LST differs in dry and lubricated conditions. In this review, direct laser ablation, laser interference and laser shock processing, which are among the LST techniques, have been examined in detail in the literature and the analysis of these techniques has been reported in this research. The effects of laser parameters on surface texturing have been examined in detail from the literature and detailed analysis has been given in graphics and tables.
