| Abstract: | This paper studies the fact that the corrosion of silver contactors in the environ- ment of various pollution concentration of H_2S and its mixture with SO_2 or Cl_2 will take place under stationary exposure, operation or salt spray condition. Observations have been carred out of the evolution of contact resistance and the surface degeneracy in various condi tions. The influence of environmental factors on contact resistance and the cause of their fail ure have been analysed by SEM and X-ray diffraction. Some significant conclusion is acheived. |
