Research on the Regularity and Mechanism of Copper Corrosion in Air Containing Sulfur Dioxide

Copper corrosion in air containing sulfur dioxide atmosphere was described in detail, for which was one of the most primary atmospheric corrosion.In the first, effection from the synergy of pure sulfur dioxide gas and mixed gas on copper corrosion was set out, together with the introduction of certain corrosion products and formation mechanism. Besides, initial copper corrosion behaviors in variety gas concentration as well as different film thickness were summarized using electrochemical method. The research prospects were depicted in the last.
