| This paper introduced the origin, development history and applications status of pulse cathodic protection technology. According to the research on pulse cathodic protection of Q235 steel and 40 angle steel in simulated seawater environment, it showed that the main parameters affecting pulse cathodic protection were pulse period, duty cycle, pulse amplitude and anode distance, etc. The advantages of pulse cathodic protection and the limitations and causes of the promotion of this technology were analyzed. Compared with the traditional DC cathodic protection technology, it showed the superiority of pulse cathodic protection technology for the protection of metal equipment structure, which can make the protection potential more uniform, make protection distance longer, and make energy consumption lower under the same protection effect. The characteristics and protection status of aluminum alloys in marine seawater environment were analyzed. Combined with the characteristics and advantages of pulse cathodic protection, according to the traditional cathodic protection theory and the electric double layer theory, the feasibility and application prospect of pulse cathodic protection technology for marine aluminum alloy protection in marine environment were prospected. |
