N2 - In the present investigation, Pt/Ru-modified bond coating consisted of 2 μm Pt+2 μm Ru was deposited on a nickel-based superalloy by electroplating method and followed by conventional Al pack cementation. The cyclic corrosion behavior of Pt/Ru-modified bond coating exposed to NaCl plus water vapor has been investigated under atmospheric pressure at 1050°C. The result shows that the cyclic corrosion life of Pt/Ru-modified bond coating is longer than that of the conventional Pt-modified aluminide coating in the presence of NaCl plus water vapor. The addition of Ru makes the coating possess the increased strength and suppress the rumpling behavior. The absence of rumpling may be responsible for the improved corrosion resistance of Pt/Ru-modified aluminide coating.
