ELECTROCHEMICAL BEHAVIOR OF ORGANIC COATINGS IN SIMULATED DEEP OCEAN ENVIRONMENT
有机涂层在模拟深海环境中的电化学行为研究

The electrochemical behavior of an Intershield 300 ENA301 coating on steel 907A in 3.5%NaCl solution was studied in a simulated deep ocean environment with a high-pressure autoclave.The results indicated that the impedance resistance and electrochemical reaction resistance of the coating under 3 MPa was tenfold smaller than that under ordinary atmosphere.The capacitance of the coating under 3MPa was higher than that under ordinary atmosphere.The characteristic frequency fh of the coating under 3MPa was grea...
