Metallic glass is a new type alloy obtained by rapid cooling and solidification in molten state. Due to the extremely short solidification time, the atoms have no time to rearrange in order. Therefore, metallic glasses have no grains and grain boundaries, and their strength, hardness, elastic limit, wear resistance and other properties are superior to traditional metals. Electric discharge machining (EDM) can not only process metallic glasses, but also prepare metallic glass layers on the surface of metal materials in order to improve the mechanical properties, such as hardness and wear resistance. In this work, the applications of EDM in the processing of metallic glasses are reviewed from two aspects: the preparation of metallic glass layers on the metal surfaces and the processing of metallic glasses by EDM.
