Corrosion resistance of various materials such as iron and steel, cermet, cermet-coated steel, ceramics and ceramics-coated steel was evaluated in molten zinc, molten aluminum-zinc alloy and molten aluminum at 470, 600, 700℃, respectively. These temperatures are commonly used in continuous molten hot dip-plating line. The results are summarized as follows : (1) All iron and steel samples tested were corroded in metal baths. But the corrosion amount was found to depend on sample composition and increased in the order Al>Al-Zn>Zn bath. Especially, the samples were severely corroded in the agitated Al bath. (2) All cermet and cermet-coated steel samples tested were corroded. Corrosion amount varied with the composition of metal bath, composition and amount of bonding metal for ceramic particles. (3) All ceramics and ceramics-coated steel samples tested were neither corroded nor markedly reacted with molten metals. However, vanadium carbide film was partially crazed and peeled off when tested in the agitated Al bath.
