| Abstract: | The Kelvin measurement device of atmospheric corrosion made by ourselves is introduced,including the measurement theory, function and usage, the soft and hard structure, and the initial measurement results. In the device,the vibrating capacitor method is used. The corrosion potential and the polarization curves of metals covered by thin electrolyte layers can be measured without touching the surface under investigation and the electrolyte,using a Kelvin probe as a reference electrode, the advanced method to study the corrosive behavior of the materials at atmosphere is given. |
