An Overview: Design of Nanocomposite Coatings

H D Gopalakrishna, Kaushik V P


The call for high productivity, quality in machined surfaces, and reduced machining costs have put a demand on the improved cutting tools. The recent advancements in development of nanocomposite coatings which consist of crystalline and amorphous phase have made dry machining at high speeds with quality in machined parts a reality. The driving force behind the super hard structure of such coatings is phase segregation mechanism. In this work, a review of the design principles of nanocomposite coatings and their oxidation behaviours in high temperatures are being discussed.
