The application of textured surfaces in tribology has recently gained a huge momentum. In this chapter, a systematic approach to investigate the maximum outcomes from employing such surfaces is introduced with an insight into their application in internal combustion engines. A combination of various affecting parameters on the tribological performance of such surfaces is studied and the optimum results were introduced. The effect of employing such optimised textures in enhancing the lubrication

Depending on the requirements for a specific application, the depth of these dimples can range from a few to several micrometres (normally 4-10µm) and their diameter can be several tens of micrometres (normally 70-100µm) 2004b) .
