Development of superhard, tough and wear-resistant nanocomposite coatings
Superhard nanocomposite coatings are attracting significant attention due to their potential applications ranging from high-powered machinery to bio-implants. The future development of these coating materials should be based on a deeper understanding of the relationship of their processing, post-treatment, microstructure and performance.
In this project, Ti-Si-N nanocomposite coatings will be prepared by magnetron sputtering. Carbon implantation will then be used to tailor their microstructure and surface chemistry for improved performance. The critical parameters that control toughening, wear and corrosion behaviour of resultant coatings will be determined and used to guide the development of advanced ceramic coatings.
