Abstract
This work aims to characterize the influence of temperature and chloride solution concentration on the corrosion behavior of a newly developed high-entropy alloy system (Al2Cr5Cu5Fe53Ni35) in a simulated marine environment. A direct correlation was found between temperature and chloride concentration with localized corrosion resistance. The Point Defect Model approach is employed to analyze the influence of the temperature and chloride concentration upon the properties of the passive film formation over the alloy surface in seawater solutions. It turns out that the present system alloy exhibits a better local corrosion resistance than conventional martensitic stainless steel UNS S40300 when temperature is below 60 ∘C in similar electrolytic environment.
