Investigation of electrochemical dissolution behavior of Ni(γ)/Ni3Al(γ') and Co(γ)/Co3Al(γ') superalloys in NaNO3 solution
Source abstract
Abstract
The electrochemical dissolution behavior of Ni(γ)/Ni 3Al(γ`), Co(γ)/Co 3Al(γ`) in NaNO 3 electrolyte solution was investigated. Experimental results showed that Al, W, and Ni ions in the γ` phase destroy the dense oxide film formed by Cr ions in the γ phase. The different dissolution rates of the γ` and γ phases led to selective corrosion on the surface of Ni(γ)/Ni 3 Al(γ`). Cobalt ions reacted with the dense Cr 2O 3 passivation film to form porous CoCr 2O 4 , and the corrosion resistance of the Co(γ)/Co 3Al(γ`) passivation film worsened due to bromination by Br − ions. Qualitative models for the ECM of the Ni(γ)/Ni 3Al(γ`) and Co(γ)/Co 3Al(γ`) are proposed.
