主　　题：Ti_(3)SiC_(2) atmosphere arc erosion 

摘      要：The effects of ambient atmospheres on the arc erosion behaviors of Ti_(3)SiC_(2)cathodes were investigated at 5.5 kV in argon,nitrogen,air,and *** mass loss of the cathodes increased in the order of argon,nitrogen,air,and oxygen and the morphologies were measured by 3D laser scanning confocal microscope with a gradual blooming *** spectroscopy,X-ray diffraction,and X-ray photoelectron spectroscopy were employed to detect the components of erosion *** erosion-chemical products mainly consisted of TiNx in nitrogen,TiN_(x),TiO_(2)and SiO_(2)in air,TiO_(2)and SiO_(2)in *** arc energy was responsible for the arc erosion characteristics in different atmospheres.
