Abstract: Anodic stripping of TiAl surface was carried out in AlCl3-NaCl-KCl molten salt at 423 K as a pretreatment for the deposit formation of an Al-Cr alloy layer. The Al-Cr alloy deposit on the TiAl significantly improved the corrosion resistance against high temperature oxidation. In anodic stripping at 0.4 V vs. Al/Al3+, anodic dissolution of surface occurred non-uniformly. On the other hand, an oxide film on TiAl was completely removed by uniform anodic dissolution at 1.2 V with electricity of 1 C cm-2. An Al-Cr electroplating layer that was formed after the anodic stripping at 1.2 V, exhibited excellent oxidation resistance that was confirmed by an oxidation test at 1173 K for 24 h.
