Abstract  

An in-field measurement system for detecting the atmospheric corrosion of aluminum alloy was built based on electrochemical noise technology. A special probe, the apparatus and software were developed for performing electrochemical noise measurement with zero resistance ammetry (ZRA) mode. Experiments were carried out in the air condition in laboratory and then in natural atmosphere outdoors. The results showed that the atmospheric corroding process could be effectively detected or monitored by analysis of the electrochemical potential and current noise and the changing of noise resistance.

Key words:  electrochemical noise      aluminum alloy      atmospheric corrosion      noise resistance
