Summary:Prostheses for implantation into the human body must be biocompatible i.e. no dissolution of the material can occur in human tissue and also, the prostheses must be corrosion resistant. Titanium nitride (TiN) possesses good mechanical, corrosion resistant, and aesthetic properties. It has also been found that such properties are not compromised in the oral cavity. Hence TiN can be readily utilised in dental prosthetics. TiN, an extremely inert compound was reactively sputtered in a closed field, unbalanced magnetron system. The substrates used included AISI 316L stainless steel. The analysis of these TiN coatings with respect to deposition parameters and their subsequent effect on corrosion resistance and porosity is outlined. Porosity before and after corrosion tests has also been examined.
