The corrosion behavior and passive film properties of the cast and annealed AlCoCrFeNi2.1 eutectic high-entropy alloy in sulfuric acid solution
The effect of microstructure on the corrosion behavior and film properties of strengthened AlCoCrFeNi2.1 eutectic high-entropy alloy (EHEA) was investigated. Annealing of the 80 % cold-rolled AlCoCrFeNi2.1 EHEA at 650–1200 ℃ effectively improved the stable passive region to 930 mV, and decreased the passive current density by 25 % to 3.5 μA/cm2 compared with the cast alloy in 0.1 M H2SO4 solution. The improved corrosion resistance of the annealed AlCoCrFeNi2.1 EHEA was attributed to the increasing oxides proportion and thickness of passive film and the reduced composition difference between FCC and B2 phases. The B2 phase in lamellae suffered the severest corrosion.
期刊介绍：
Corrosion occurrence and its practical control encompass a vast array of scientific knowledge. Corrosion Science endeavors to serve as the conduit for the exchange of ideas, developments, and research across all facets of this field, encompassing both metallic and non-metallic corrosion. The scope of this international journal is broad and inclusive. Published papers span from highly theoretical inquiries to essentially practical applications, covering diverse areas such as high-temperature oxidation, passivity, anodic oxidation, biochemical corrosion, stress corrosion cracking, and corrosion control mechanisms and methodologies.
This journal publishes original papers and critical reviews across the spectrum of pure and applied corrosion, material degradation, and surface science and engineering. It serves as a crucial link connecting metallurgists, materials scientists, and researchers investigating corrosion and degradation phenomena. Join us in advancing knowledge and understanding in the vital field of corrosion science.
