Surface micro-texturing deals with the issues pertaining to various fields of engineering for enhancing essential functions such as tribological, wetting, biocompatibility, sustainability, cleanliness, etc. Among all the aforementioned sectors, micro-texturing of curved/free-form large areas is getting huge attention, e.g. micro-textures on artificial biomedical implants enhance sustainability and life cycle by better implant-tissue interface, cell-adhesion, and cell proliferation. Due to growing awareness towards the significances of micro-texturing, presently a lot of thrusts are being given on innovations employing surface textures on free-form/curved surfaces. The paper proposes a porous and flexible electrode based through-mask electrochemical micromachining (TMECMM) in which surface of any curvature can be textured by adapting the shape of the surface. A 3-D numerical simulation of the TMECMM texturing executed …
