Effects of additives on the AgSnO2 contacts erosion behavior

• 摘要：

  The switching performances of several improved silver tin-oxide materials with some kinds of additives, including WO3,Bi2O3,In2O3, were conducted in accelerated testing machine. Based on the experimental results and the observations of the contacts surface microstructure, the effects of additives on the silver tin-oxide contacts erosion behavior are mainly studied. It is indicated that the effects of additives on the wettability between liquid silver metal and the contact surface, the distribution and the thermal stability of additives are critical in the decision of erosion characteristics and the morphology feature of contact surface. The erosion behaviors of silver-tin oxide materials with different additives are compared, the doping effect on surface morphology is presented.
