In-situ observation on the self designed thermal spraying metal coating for long time protection to the jackets of Center No. 2 platform in the Shengli Oil Field in Chengdao showed that the spraying aluminum coating had good corrosion resistant effect on the marine platform. The base was protected from corrosion even when the organic painting on surface had fallen off. Mere aluminum coating could not provide good electrochemical protection to the base near the water line.The coating's protective effect in the marine atmosphere zone did not decrease even when the organic paint on the surface was scuffed up or had dropped. The organic paint used to seal the spraying metal coating must have high cohesive affinity and penetration. The two years experiment in the open sea showed that the most economic and effective protective method is to spray zinc coating first, then spray aluminum coating and then to seal the metal coatings with alloprene paint.

通過自然環境譜設計實驗室加速試驗譜,對交聯聚烯烴護套電纜開展了南海海洋大氣環境試驗和實驗室組合試驗,并且根據外觀、機械性能檢測了護套在西沙戶外不同周期大氣暴露試驗和實驗室組合試驗后的性能變化規律,并進行相關性計算.結果表明,由濕熱、光老化和鹽霧三種試驗組成的組合試驗與自然環境試驗的相關強度是極強相關.
