A review on Corrosion of High Entropy Alloys: Exploring the Interplay Between Corrosion Properties, Alloy Composition, Passive Film Stability and Materials Selection

The corrosion resistance of high entropy alloys was reviewed in the present work. main focus to explore correlation between alloy composition, passive film stability and properties use this information develop a materials selection procedure based on Ashby approach. Corrosion current densities pitting potentials were design parameters used rank different alloys, careful examination data published literature, considering uniform localized corrosion, respectively. outputs process clearly indicated strong dependence stability, although microstructural homogeneity distribution alloying elements should not be disregarded. Proper combinations such as Co, Al, Ti, Mo Cr, especially, are effective at enhancing alloys.
