Introduction of Automotive Tribology

Tribology is existed at the interface of two materials which are in relative motion and this causes friction at the interface. Due to friction, heat is generated between two meting surfaces which causes wear on surfaces either one or both the materials. To reduce friction and wear at interface, a lubricant is supplied. This lubricant may be either solid lubricant such as graphite, graphene etc. or liquid lubricant such as base oil, mineral oil etc. or semisolid lubricant such as grease. In this chapter, the detailed description of friction, wear and lubrication is given. Furthermore, a number of examples are also presented where tribology is very important such as bearings, gears, engines, orthopaedic joints and micro-machines. At last, the brief introduction of important applications are also discussed along with brief prescription about book chapters.
