Abstract
Gas spark switch is the most commonly used key device in pulse power device. The difficult problem of electrode erosion, which affects the performance of gas spark switches, has always become a bottleneck restricting the development and application of gas switch. This article reviews the existing electrode erosion theory and experimental research results, introduces the basic mechanism and simulation model of electrode erosion, summarizes the factors affecting the switching electrode erosion and the research progress of erosion-resistant electrode materials, and finally discusses the problems faced by the erosion research and the direction of optimizing the erosion resistance of the electrode materials.
