Abstract

This chapter deals with a variety of ceramic and cermet composite coatings capable of protecting the industrial components including strategic and aerospace sectors from various damage mechanisms such as wear, corrosion, oxidation, thermal, fatigue, and combinations thereof. To enable such coating deposition, a spectrum of processing techniques such as plasma spray, high-velocity oxy-fuel spray, detonation spray, micro-arc oxidation, and laser cladding techniques were utilized and considered for detailed discussion. Under each of the aforementioned techniques, the processing fundamentals, influence of process variables, typical microstructures, properties, and performance of the resulting coatings were briefly presented. However, only the coatings that are functionally relevant in the working temperature up to 800 °C were considered in this chapter. A special emphasis has been placed to provide the understanding of structure-property-performance aspects of different coatings such that the information can be correlated with the typical industrial requirements. Further, both the demonstrated and potential applications specifically pertaining to strategic and aerospace sectors were exemplified.
