Abstract:

The WC-Co coating obtained by thermal spraying technique is one of the most important and widely used coatings for tribological applications. In this chapter, various methods of spraying WC-Co coatings are discussed along with their microstructural features and mechanical properties. Further, the tribological performances of these coatings are described in detail. This chapter is also concerned with various tribological applications and the direction of future research.
