摘　　要：采用熔盐保护合成法制备Ti_(3)SiC_(2)粉末材料,并将该粉末进行热压烧结,制备出Ti_(3)SiC_(2)块状样品。在加载电压10 kV下,对Ti_(3)SiC_(2)块状材料进行电弧烧蚀性能研究。电弧烧蚀后,Ti_(3)SiC_(2)块状材料表面出现烧蚀痕迹,电弧熄灭后,裂纹和显微孔洞显现。结合拉曼光谱和X射线能谱结果,高能高热的电弧使得Ti_(3)SiC_(2)块状材料表面有Ti和Si的氧化物生成。In this paper, Ti_(3)SiC_(2) powder was prepared by molten salt protection synthesis method, and Ti_(3)SiC_(2) bulk samples were prepared by hot pressing sintering. Under the load voltage of 10 kV, the arc ablation performance of Ti_(3)SiC_(2) bulk material was studied. After arc ablation, ablation marks appeared on the surface of Ti_(3)SiC_(2) bulk material, and cracks and micro holes appeared after the arc was extinguished. Combined with the results of Raman spectroscopy and energy dispersive X-ray spectroscopy, Ti and Si oxides were formed on the surface of Ti_(3)SiC_(2) bulk materials due to high energy and high heat arc.
