The results show that potentials of the steel sample have small difference,and don't exceed 20 mV under common instances;galvanic couple corrosion phenomenon is light or ignored under oxygen and short term.

Analyzes the work state of a thermoelectric cooling device based on the performance of galvanic couple.

Based on the performance of galvanic couple,this paper gives a brief discussion about the performances at varied operating conditions ,and the range of working valtage and current is presented.

Some typical forms such as stress corrosion,chink corrosion and couple corrosion are analyzed.

The corrosion potential of 16 Mn steel respectively in the zones of full immersion, tide range and splash is measured by putting the independent test pieces put into sea water corrosion simulation test unit and the couple potential, couple current and their corrosion speed of the electrically connected test pieces in the above 3 zones are also measured.

According to dynamics of coupled sacrificial anode with carbon steel,the integral of galvanic current vs.

To study the effect of rate between cathodic and anodic area,and temperature on galvanic corrosion of these two kinds of steel,electrochemical techniques were used to analyze galvanic current and interface configuration on anodic electrode.
