According to the change of microstructure and electrochemical function of alloy, the microstructures of Al Zn - In alloy and the open path of alloy in 3%NaCl solution are studied by means of electron probe (EPMA), potential polarization and constant current polarization. The influence of electric potential such as potential, working potential, erosion morphology and current efficiency. Any problem of sacrificial anode system is checked by the construction unit.lb27217317

The aluminum alloy sacrificial anode is suitable for the metal structures in the seawater medium and the anticorrosion and protection of the metal structures in the offshore oil transportation, gas pipeline, underground cable, communication and other engineering. The results show that the average treatment of 10h reduces the segregation of grain boundary segregation, inhibits the self erosion of hydrogen and the grain loss and improves the current efficiency, but has no significant effect on the open potential, working potential and dissolution behavior of the anode, and the current efficiency of the water quenched sample is the highest.
The aluminum alloy sacrificial anode has extremely high electrochemical function, and the anode material with a unit weight generates a large amount of electricity, about three times that of the zinc anode and two times of the magnesium anode..lb27217317​

After the completion and acceptance of the anticorrosion project, 2-3, 10, and 25 years by the construction unit or the owner of the independent third parties with testing qualifications to carry out three submersion visual inspection and measurement.

​

直流电硫酸阳极氧化法的应用最为普遍, 这是因为它具有适用于铝及大部分铝合金的阳极氧化处理；膜层较厚、硬而耐磨、封孔后可获得更好的抗蚀性；膜层无色透明、吸附能力强极易着色；处理电压较低,耗电少；处理过程不必改变电压周期, 有利于连续生产和实践操作自动化；硫酸对人身的危害较铬酸小, 货源广, 价格低等优点。.lb27217317
