摘　　要：文献归纳了不同材料的电极的烧蚀速率,定量分析了不同电极材料不同放电条件(放电电压和峰值电流,放电重复频率,放电介质,放电能量)电极烧蚀的速率。一般而言,电极的烧蚀量与放电电压、电容储能、峰值电流和间隙距离成正相关,与放电时延成负相关。不同的放电条件钨铜的烧蚀速率都比较小,抗电极烧蚀性能强,讨论了特殊的材料的放电现象如放电条件、等离子体喷溅等对电极烧蚀率的影响。The electrode erosion rate of different materials are summarized in the literature,and the electrode erosion rate of different materials under different discharge conditions(discharge voltage and peak current,discharge repetition rate,discharge medium,discharge energy)are quantitatively analyzed.Generally,the erosion amount of electrode is positively correlated with discharge voltage,capacitor energy storage,peak current and gap distance,and negatively correlated with discharge delay.The erosion rate of tungsten and copper is relatively smaller under different discharge conditions,and the electrode erosion resistance is strong.The effects of discharge phenomena of special materials such as discharge conditions and plasma splashing on electrode erosion rate discussed.
