Effects Of Lanthanum On The Microstructure, Electrochemical Behavior, And Anti-Corrosion Properties Of Zinc-Copper-Titanium Alloy In 3% Sodium Chloride Solution
MATERIALS AND CORROSION-WERKSTOFFE UND KORROSION(2017)
摘要
SEM analysis shows that trace amounts of La in Zn-Cu-Ti alloy can eliminate dendritic segregation and produce uniform organization. Analyses of Tafel polarization curves and EIS show that La can obviously improve the corrosion resistance of Zn-Cu-Ti alloy by two features: (i) La oxide film has strong barrier properties; (ii) with an increase in La content, the thick skeletal dendrite epsilon(primary crystal) phase disappears and the more refined and dispersed epsilon(II) phase is generated, leading to a decrease in the active cathode area. Zn-Cu-Ti-0.5La alloy has the best corrosion resistance. The corrosion of the investigated alloys is mainly selective.
