摘要
In this work, the galvanic corrosion rate, the electrochemical polarization curves and micro morphology of three-phase coupling composed by low alloy steel 907, 921 and copper -nickel alloy B10 under different pressure in simulated deep-sea environment were studied by means of the weight loss method, the electrochemical method and the scanning electronic microscope (SEM), respectively. The results showed that pressure had little influence on the stable galvanic potential. When the pressure was less than 1000m, the corrosion of steel 907 was the most serious. While above 1000m the galvanic corrosion focused on steel 921.
