SEMINAR: Wear and Corrosion Resistance of Cathodic Arc Physical Vapour Deposition Coating on Titanium Alloys for Biomedical Use
PRESENTER: Ms. Ay Ching Hee, School of Mechanical, Materials and Mechatronic Engineering, Faculty of Engineering and Information Sciences, University of Wollongong
WHEN: 12.30 - 13.30, 29 May, 2015
ABSTRACT: Titanium (Ti) alloys are widely used as biomaterials particularly for cardiovascular, dental and orthopaedic owning to their low elastic modulus, superior biocompatibility and enhanced corrosion resistance compared to conventional stainless steel and cobalt-based alloys. However, high wear rate and high friction coefficient associated limits the lifespan of the titanium alloys as suitable implant materials. Physical vapour deposition coating is one of the techniques to improve the mechanical properties and reduce the wear rate of the Ti alloys. Implant biomaterials like diamond like carbon and tantalum coatings have shown growing interest in the recent years. The mechanical and tribological results of the coatings will be presented and discussed. Research objectives and research plan will be outlined.
