“…They suppress abrasion and ploughing friction and third-body wear, resulting in improved fretting fatigue resistance, longer durability and hence reliability. This is very common idea amongst different researchers such as Blatter et al (1999), Fenske et al (2003), Alberdi et al (2004), Erdemir et al (2004a and b), Kovalchenko et al (2005), Etsion (2005), Wong et al (2006), Andersson et al (2007), Costa and Hutchings (2007), and Krupka and Hartl (2007).…”

“…Detailed mechanisms of friction reduction are not fully understood and the lubrication phenomena induced by the micro-geometry distribution remain widely unknown (Mourier et al, 2006). Moreover, the influence of size and shape of the surface texture on their tribological performance is not well known either (Alberdi et al, 2004). In fact, the maximum benefits that can be accrued from sophisticated texturing are unclear and this area is relatively unexplored.…”

“…The electrical discharge etching has also been used by Ito et al (2000). Using combined techniques of PVD (physical vapour deposition) and UV photo-lithography has been reported in the literature as well Alberdi et al, (2004). Costa and Hutchings (2007) have used photochemical etching, which comprises masking by photolithography followed by chemical etching.…”

“…Methods including deep RIE (reactive ion etching) , different forms of etching and UV lithography can produce a variety of shapes in both metals and ceramics (Alberdi et al, 2004 andWong et al, 2006). Early studies have used photo-etching for micro-asperity fabrication (Siripuram, 2003 andHsu et al, 2003).…”

“…These features can retain lubricant to release when needed, thus increasing the quantity of the lubricant locally even under high pressures (Blatter et al, 1999, Fenske et al, 2003, Alberdi et al, 2004, Uehara et al, 2004, Mourier et al, 2006and Andersson et al, 2007. The liquid trapped in the low valleys of the textured surfaces can be considered as a secondary source, which is then drawn by the relative movement of the surfaces to seep into the surrounding areas by capillarity action, and therefore, reduce friction and reduce the chance of galling (Wang et al, 2001 and2003).…”

RAHMANI, Loughborough University, UK A. SHIRVANI and H. SHIRVANI, Anglia Ruskin University, UK Abstract: 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 condition in piston ring/cylinder liner contact is also studied.Key words: surface texturing, piston ring/cylinder liner contact, optimisation, slider bearings IntroductionIn general, friction is inherent to and is produced between bodies in contact with relative motion. Friction tends to oppose this relative motion between the bodies through loss of energy mostly in the form of heat, mechanical vibration and noise. Therefore, in most cases, friction is an unfavourable phenomenon. In some cases introduction of friction is desired, for example in order to slow down a moving car, the brakes are used to reduce the existing kinetic energy in the wheels by means of producing frictional losses. However, in most of the cases, facilitating this relative motion between bodies is of concern and as a result, one needs to overcome friction so that the relative motion pursues with a minimal loss of energy.Excessive friction can cause damage to the surfaces in contact in several ways and as a result make them wear. Since the surfaces are damaged due to wear, the rate of energy dissipation due to friction increases and consequently amplifies the rate of wear itself (see Chapter 2).The reason for the existence of friction is mainly that in reality, there is no perfect smooth surface. In fact, surfaces have a degree of roughness in the form of small 'hills' and 'valleys' no matter how well they are prepared. When two surfaces, which are in contact with each other, are put into relative motion, the asperities on the In: Tribology and Dynamics of Engine and Powertrain: Fundamentals, Applications and Future Trends, Edited by H.

The micro-cycle lubrication phenomenon generated by a grid-textured surface is investigated through experiments. The experiments involve designing a grid-textured surface and observing its lubrication behavior. Results show that the gridtextured surface helps set up hydrodynamic lubrication micro-region pressure and peak value locals at the intersection points of the grooves. The grid-textured surface decreases graduation from the intersection point to the center of the rhombus. The experiments show that micro-cycle flow improves lubrication and wear. A simulation model is developed to investigate lubrication. The comparison of pressure distribution on the grid-textured and smooth surfaces reveals the details of lubrication behavior.

It is well known that the tribological performance of materials highly depends on the surface topography. An experimental research to determine the friction coefficients for a few couples of material such as microtextured silicon/stainless steel, aluminium, copper, FR4 (epoxy-glass laminate) and PVC (Polyvinyl Chloride) is presented in this paper. (100) oriented monocrystalline silicon, microtextured through MEMS (Microelectromechanical Systems) technologies, was used. The influence of surface roughness on the static friction coefficient has been studied also. The experimental results have been validated by simulation with 20-sim software.
