Abstract

The presented article describes the effects of laser micro texture of the surface of construction materials used in civil aviation, aeronautics and the automotive industry. For this purpose, a laser with ultrashort pulses generating UV radiation was used. The authors presented the possibility of micro machining of INCONEL 718 alloy surfaces. The texture made can be used in many modern industrial applications relevant to the development of technology. One of such applications is the development of surfaces to increase the adhesiveness of bonded joints to other construction materials. The TruMicro 5325c laser used for this purpose allows the material to be processed using a cold ablation process, which allows precise, selective removal of the material without a thermal influence on the adjacent areas of the workpiece.
