Although molten salt electroplating is interesting method to develop new pre-coated steels, there has been little commercial exploitation because of powdery and/or dendritic deposits. In this study, the electroplating of Al, especially Al-Mn alloy on steel sheet in AlCl3-NaCl-KCl molten salt bath is focused. High speed fluid flow of molten salt and deposition of Al-Mn alloy were found to be most effective to smooth-faced deposition at high current density. Consequently, ultra-smooth lustrous deposit with amorphous structure was generated.
