Detonation Sprayed Coatings for Aerospace Applications

Abstract

This chapter presents a concise overview of detonation spray technology and the associated principles and applications for the aerospace industry. The most popular feedstock powders for obtaining a wide variety of coatings with varying composition and properties are emphasized. The strategies for obtaining improved structure–property combinations via spray process optimization are discussed, and also the utilization of novel powders for enhanced protection. The typical microstructural features as a key to achieving the required mechanical, tribological and corrosion properties are briefly illustrated with specific examples.
