Surface texturing is a process of inducing specific patterns on a surface to enhance the performance of the surface in its working environment. The arrays of patterns can be either micro-scale, nano-scale, or its combination. In general, micro-texturing of a surface regulates the surface energy and contact angle (CA), which can lead to hydrophobicity and improved tribological properties to the surface. Laser surface texturing process (direct write method) is one of the best suitable processes for producing micro-patterns because of its better accuracy, repeatability, and machining rate over the advanced machining processes (electric discharge machining, electrochemical micro-machining, etc.). In the present work, an attempt has been made to produce micro-textures on polymeric as well as metallic surfaces using CO₂ laser and solid-state pulsed ytterbium fiber laser respectively. An experimental analysis is …
