Abstract :
In order to effectively reduce and retard corrosion of the power transmission and transformation equipment in Chengdu powergrid and to improve power supply reliability, Q235 carbon steel material which is the most widely used metal material in powergrid was selected as the targeted research object in this article. Exposure experiments were performed in urban atmosphericenvironment of Chengdu city in the southwest region of China. The corrosion behavior of Q235 carbon steel material wasinvestigated at different seasons. The macro- and micromorphologies after corrosion were observed using a digital camera andscanning electron microscopy (SEM), respectively. Element distribution of the rust layer and the corrosion products wascharacterized by energy-dispersive spectroscopy (EDS), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy(FTIR); the corrosion mechanism was also briefly analyzed
