Ag-SnO2 contact materials with different SnO2 contents were prepared by powder metallurgy, and the effect of SnO2 content on the arc erosion behavior of the materials was studied. The erosion surface morphology of Ag-SnO2 contact materials were characterized by scanning electron microscope, and the factors influencing arc erosion were analyzed as well. The results show that the arc erosion prefers to occur on SnO2 particles. With the SnO2 content increasing, the arcing duration extends, the erosion area decreases and the erosion pits deepens, resulting in an obvious molten metal splash.
