ABSTRACT
Microtexturing is the art of miniaturization of patterned surfaces. Depending on the applied texturing method and surface functionalization for a particular application, microtextures can be produced as micro-pillars and micro-pits. Surface microtexturing is the method of generating précised arrays of indistinguishable micro/nano-features on the surface to change its surface 294topographies of their functionality and product life. Hence, patterned substrates are implicitly microtextured engineered surfaces, regardless of the pattern type. The term ‘microtextured surfaces’ characterize the exteriors that comprise several features, such as micro-holes, micro-dimples, micro-square pattern, etc., of significant geometrical parameters. The categorization of microtextures is required by the sum of their prime symmetrical features such as shape, size, density, dimensions (dependent on the geometric shape), distribution on the surface, etc. In current times, microtextures are used in several fields, such as metrology, electronics, optics, tribology, biomedicine, etc. Primarily, the practical properties of microtextured surfaces are from the environment. For a better insight into micro-texturing using the electrochemical micromachining (EMM) process, fundamental concepts such as electrochemistry, limitations, and advantages are discussed. The investigation into the generation of micro-ellipse patterns is carried out in this chapter.
