Research progress in corrosion resistance of high-entropy metallic glasses

Abstract

The high-entropy metallic glasses, as a new kind of alloyed materials, have attracted considerable attention due to its excellent mechanical, anti-corrosion and magnetic properties and so forth, which combines the advantages of high-entropy alloys and metallic glasses. Herein, a comprehensive understanding of the concepts and features of high-entropy metallic glasses was provided as well as its preparation methods, distinguished structure and performance characteristics. The recent developments in the corrosion resistance mechanism and anti-corrosion properties were summarized. A new paradigm of using machine learning to design high-entropy metallic glasses was prospected. It was also pointed out that the precondition to the extensive use of this sort of materials is to explore the corrosion failure mechanism under the working conditions, and to achieve the micro-corrosion resistance mechanism perfection and its preparation process optimization. At present, the applied basic research on the development of high-entropy metallic glasses and its corrosion resistance will provide advanced technical support and material guarantee for the "Marching into the deep ocean" of China’s marine industry.
