Improving the corrosion resistance of Ti6Al4V alloy through TiN/polyaniline hybrid films produced by plasma nitriding and PECVD
Özet
Ti6Al4V alloy is widely used as an implant material but it can release harmful metal ions during its use. One of the most effective ways to improve biocompatibility of Ti6Al4V alloy is to apply surface treatments. For this reason, this study aims to investigate the effects of polyaniline (PANI) thin film coating and plasma nitriding processes, both individually and together, on the structural, morphological and corrosion properties of Ti6Al4V alloy. While the PANI thin film coated samples by PECVD and duplex coated samples were shown hydrophilic character, hydrophobic character was dominant in the plasma nitrided samples due to titanium nitride (TiN) formation on the surface. PANI coating improved the corrosion resistance of the material. Plasma nitriding also improved the corrosion resistance of the material due to the formation of protective TiN containing surface layers. Lattice and thermal mismatches hindered the obtaining much more corrosion resistance for only PANI coated, plasma nitrided and plasma nitrided + PANI coated samples. Overall results showed that the plasma nitrided + PANI film coated samples exhibited the best corrosion performance due to the protective barrier effect provided by PANI film and nitride layers.
