| Abstract Scope |
Electroplating is a promising approach to utilize the superior properties of titanium, such as corrosion resistance and biocompatibility. Even complex-shaped materials can be coated by electroplating. Generally, compact and smooth Ti films were obtained from fluoride melts such as LiF–NaF–KF. However, one of the problems using fluoride-based molten salts was the difficulty in removing the salt adhered to the deposited Ti due to low solubility of LiF and NaF in water. Recently, we have proposed a new electrodepositon process of Ti using water-soluble KF–KCl molten salts. This paper presents the electrodeposition of Ti and the electrochemical behavior of Ti(III) ions in molten KF–KCl. Moreover, comparison with the results obtained in LiF–LiCl will be given to discuss the effect of cations on the electrochemical behavior of Ti ions. |
