 This study examined the synthesis of AG-SNO2-CNO by powder metallurgy methods and their subsequent electrical contact behavior. The material was prepared by ball milling and hot pressing, and then subjected to arc erosion testing. The microstructure and phase evolution of the material were studied with x-ray diffraction, energy dispersive spectroscopy, and scanning electron microscopy. The results indicated that the AG-SNO2-CNO composite had a higher mass loss during the electrical contact test compared to the commercial AG-CDO, but maintained consistent electrical conductivity. This suggests that the reaction of X-N2-SNO4 formation on the surface of the material may control the surface segregation and subsequent loss of electrical conductivity, which could lead to the development of a new environmentally friendly electrical contact material.
