**1. Introduction**

Tribology is defined as the science of sliding two surfaces in relative motion. It comprises the investigation and application of the wear, friction and lubrication. The term called tribology has been realized for thousands of years. In the year of 1966, the well-known 'Jost Report' was released to the government of British. Since, the term called 'tribology' has been broadly used and the investigation on this topic has been highly explored. This is an interdisciplinary area and related with materials, wear, friction, surface analysis, wear mechanism and working atmosphere [1]. Also, the surface properties of the base material cannot be measured totally as independent. It involves the component shape with contact types i.e., static or dynamic for the essential performance and reliability. The wear resistance of the material is mainly depending on the loading type, sliding and working environment. However, the phenomena are more complicated, in that a surface wear properties based on many tribological factors namely sliding type, mode of loading and working atmosphere [2]. Further, the wear behavior examination includes wear rate, coefficient of friction, volume loss, worn-out morphologies examination and studies of the mechanical properties and microstructure. Jeyaprakash et al. performed the laser coating and studied the wear resistance, friction behavior and various wear mechanisms [3]. Jin et al. performed high entropy alloy coating and studied the mechanical and wear properties [4]. Si et al. produced the Fe–Mo–Cr–Co coating and studied the wear resistance and corrosion resistance properties [5]. From the above literature, it has been recognized the importance of tribological properties. The main objective of this chapter is to study the tribology fundamental, friction, lubrication, wear, mechanism.
