Abstract
This presentation gives an overview of nanostructured ceramic films and coatings that have been developed using eco-friendly, non-vacuum and scalable aerosol assisted chemical vapour deposition (AACVD) processes with well controlled structure and composition at molecular level. The fundamental aspects of AACVD including process principles, deposition mechanism, reaction chemistry, kinetics, and mass transport phenomena will be presented. The relationships of the process/structure/property of the coatings fabricated by AACVD based methods will be described. The scientific and technological significant of these methods will be discussed and reviewed. AACVD is a variant of the CVD process. It has the capability to deposit high purity nanostructured thin and thick ceramic coatings at low processing temperatures. The potential applications of such cost-effective and high performance ceramic coatings for structural, functional and biomedical fields will be highlighted, covering ceramic coatings for extreme environments, tribology, energy generation and storage, as well as coated medical implants and devices. The technical viability and the potential of the AACVD process to be scaled up or large area and large scale production will also be presented
