| Abstract Scope |
A structure, composition, and processing paradigm governing the corrosion properties of MPEAs has not yet emerged. Corrosion properties depend on many factors. The quest for superior corrosion properties requires an understanding of the fate of each element during corrosion, the functions of elements whether in the alloy, substrate or both, and the ability to harness interactive effects. Gaps in knowledge still exist regarding the (a) specific functions of each element, (b) the effects of elements in unusual combinations, and (c) possible formation of complex protective oxides that regulate corrosion and breakdown. Guiding principles relevant to specific alloy families are beginning to emerge such as the identification of certain specific elemental roles, functions, and types of nearest neighbor atomic interactions which may be beneficial. These issues are discussed with the goal of accelerating the understanding of the corrosion behavior in this class of materials. |
