Abstract Scope |
Corrosion is a natural occurring process. A metal that is chemically unstable in a certain environment will degrade. To withstand a certain corrosive environment, a material needs to be specially designed so that the lifetime, reliability, and safety could be ensured. In recent years, the study of corrosion behavior of high-entropy alloys (HEAs) has been conducted extensively, since HEAs may contain a high content of passivity-inducing elements, such as chromium, nickel, molybdenum, aluminum, titanium, and others. The corrosion behavior has been investigated in high-pressure and high-temperature water, chloride-rich environments, and acid solutions. These investigations provided a new knowledge that each alloying element plays a significant role in the protective passive film formation. Other significant factors include processing methods, which would influence the microstructure of the HEAs, and thus, corrosion behavior. High-throughput corrosion experiments will be discussed. The corrosion behavior of HEAs will be compared to commercial alloys. |
