The influence of the tribology over the life -cycle´s products and economy

The study of FRICTION, WEAR, and LUBRICATION is of enormous practical importance, because the functioning of many mechanical, electromechanical, and biological systems depends on the appropriate friction and wear values. In recent decades, this field, termed tribology, has received increasing attention as it has become evident that the wastage of resources resulting from high friction and wear is greater than 6% of the Gross National Product. The potential savings offered by improved tribological knowledge are immense. However, most engineers do not have a sufficient background in this area. For example, an undergraduate engineering student receives perhaps an hour of instruction in tribology. Moreover, most reference works of tribology provide little guidance to solving real-world problems. We presents current insights into tribology, focusing on such fundamental concepts as surface energy, elastic and elastoplastic deformation, micro-fracture, and surface interactions.
