Coating properties

Abstract : In this chapter, coating properties are discussed in the light of the coating microstructure which is the topic of a first specific subchapter due to specific features related to the cold spray itself. The chapter refers to particles, splats and coatings, which result in subheadings but not systematically. The content mainly elaborates on characteristics, phenomena and properties, but also on particular characterization methods provided that they are not conventional and especially suitable for the study of cold spray issues. The first subchapter (Sect. 4.1) is devoted to microstructure since this cannot be disconnected from that, and it is more commonly termed as coating properties. This emphasis is all the more justified as, all in all, microstructures are rather seldom discussed in publications dealing with cold spray. However, considering microstructures is highly relevant to discuss the mechanical and physical behaviour of cold spray coatings due to some specific aspects of cold-sprayed materials, at a submicronic scale in particular. The authors try to highlight what is typical of cold spray rather than adopting a systematic approach to properties per material or per application. For this reason, the scope remains mainly limited to metallic coating materials even though some parts may refer to polymers and ceramics, which can still be considered as exotic, not to say unsuitable, materials for cold spray.
