The arc erosion behavior of Ti₃AlC₂ in oxygen, air, nitrogen, carbon dioxide, argon, and sulfur hexafluoride atmospheres at 9 kV voltage was studied. The breakdown strength increased in the order of oxygen, air, carbon dioxide, nitrogen, argon, and sulfur hexafluoride, whereas the arc energy decreased. Cracks, pits, and bulges on the eroded surface were investigated using scanning electron microscopy and three-dimensional (3D) laser confocal scanning microscopy. Raman spectroscopy and X-ray photoelectron spectroscopy (XPS) were used to determine the composition of the eroded surface. The arc energy and electromagnetic force lead to the formation of erosion characteristics. The mechanism of erosion under the different atmospheres is discussed systematically, and is called the “decomposition-oxidation” process in oxygen, air, and carbon dioxide and the “decomposition-rereaction” process in nitrogen and sulfur hexafluoride. This study provides a reference for the application of MAX phase materials in high-voltage electrical appliances.

Ti ₃ AlC ₂的电弧腐蚀行为研究了在9 kV电压下在氧气，空气，氮气，二氧化碳，氩气和六氟化硫气氛中的温度。击穿强度按氧气，空气，二氧化碳，氮气，氩气和六氟化硫的顺序增加，而电弧能量却降低。使用扫描电子显微镜和三维（3D）激光共聚焦扫描显微镜研究了被腐蚀表面上的裂纹，凹坑和凸起。拉曼光谱和X射线光电子能谱（XPS）用于确定腐蚀表面的成分。电弧能量和电磁力导致形成腐蚀特征。系统地讨论了在不同大气条件下的腐蚀机理，这被称为在氧气，空气中的“分解-氧化”过程，二氧化碳和六氟化氮和六氟化硫中的“分解-反应”过程。该研究为MAX相材料在高压电器中的应用提供了参考。
