Investigation of Aerosol Cold Spray Technology for Ceramic Coatings Deposition

Aerosol deposition (AD) is a modification of low pressure cold spray technology which allows the deposit of ceramic based coatings. AD technology in a vacuum allows the formation of dense and well adhering ceramic films from sub-micro and nanoparticles directly at room temperature. The AD technology is still under development to cover more applications and discover solutions of spraying different kinds of powders on different types of material substrate and optimizing spraying conditions to obtain the best results. The main objective of the project is to investigate a new AD cold spray technology for Hydroxyapatite (HA) and Zirconium Dioxide (ZrO2) ceramic powder deposition onto both the implants and engine components. The new AD spraying system will be constructed and tested to obtain data that will have a significant effect on the development of ceramic coating structures and properties, and will allow spraying of nano-particles onto various substrates to achieve unique material properties. Application prospects of the AD cold spray technology will be defined and the first trials of AD process for orthopedic implants will be performed.
