ABSTRACT

The main drawback of most engineering materials is poor corrosion and wear resistance. To overcome this, several composites were made with hard and soft ceramic reinforcements using various manufacturing processes. These composites exhibited a better wear resistance; however, special attention is required to control the corrosion process. Composite fabrication has been used with surface modification techniques in recent years to yield good wear and corrosion resistance. The surface modification process could allow the selection of matrix and suitable reinforcement materials to be deposited on the surface of the substrate. There are various reinforcements used for the tribology application. However, for the past few years, the focus on the use of calcium and bio-based reinforcements for tribology application is increasing because of their lubrication. Hence, this chapter discusses the recent work carried out on the influence of calcium and its derivative compounds on the tribology properties of various coatings. Also, the importance of biocompatible coating for biomedical tribology applications is discussed in detail.
