Paper Abstract

The article presents the results of laser microtexturing on the surface of structural materials used in aeronautics, civil aviation and the automotive industry. Using the laser with ultrashort pulses and UV radiation, the authors presented the possibility of surface treatment of titanium alloys. The microtexture can be used for many different industrial applications. One of such applications is to increase the surface area in order to increase the adhesive of bonded joints to other structural materials. The UV laser with ultra-short pulses used for this purpose allows micromachining of the material using the cold ablation process, which does not damage the material when it is micromachining. The research carried out by the authors is aimed to verifying how features such as the shape, density and depth of the laser-made microtexture affect to the strength of the constituted adhesive joint for the tested pair of materials.
