Research on the Corrosion Phenomenon of Iron Parts in the Internal Micro-environment of Relay

EasyChair Preprint no. 2470

Abstract

     With the continuous improvement of reliability requirements of relay products, more attention has been paid to the influence of varied micro-environment caused by the production of arc during the operation. In this paper, the corrosion phenomenon of iron parts of relays after electric life test has been analyzed, and it is confirmed that the formation of acidic substances is the primary cause of the corrosion of iron parts, where the acidic substances are the reaction production of water vapor (H₂O) and compounds of nitrogen and oxygen (N_xO_y) produced in air atmosphere under the action of arc. According to the corrosion mechanism, the varied internal micro-environment of relays during the electric life test has been simulated, and a rapid method for the evaluation of the corrosion resistance of the iron parts has been carried out.
