Effects of plasma nitriding and TiN coating duplex treatment on tribological and electrochemical properties of cast pure titanium

摘要

The effects of different surface treatments on tribological and electrochemical properties of cast pure titanium were investigated.In this study two different surface treatments were performed which were TiN film deposition by arc ion plating,duplex treatment of plasma nitriding and TiN film deposition.Both surface treatment improved tribological and corrosion behavior of cast titanium.The duplex treated specimens exhibited higher surface hardness,better wear and corrosion resistance compared with TiN film deposited ones.All these results indicate that plasma nitriding and TiN film deposition duplex treatment can improve surface characteristics of cast titanium significantly.
