| 摘 要： | 通过电化学噪声方法研究了腐蚀介质处于流动状态和静止状态时,J55套管钢在不同时间内的腐蚀情况对比.试验结果表明:静态与动态腐蚀均随着腐蚀时间的延长,腐蚀产物膜逐渐加厚,腐蚀速率逐渐下降；腐蚀达到一定时间以后,两种腐蚀均会达到一个恒定的腐蚀速率,此时腐蚀产物膜厚度不再增加.静态腐蚀与动态腐蚀随时间变化的大致趋势相同,但动...

| Abstract: | By electrochemical noise method,when corrosive medium is respectively under dynamic and static state,the J55 casing steel corrosion was compared under different time.The test results showed that corrosion film will thicken gradually with corrosion time prolonging under two corrosion states,and corrosion rating will decrease;when the corrosion time lasts some time,the corrosion rating will reach a static value and the thickness of corrosion film will not grow any longer;the dynamic corrosion and static corro... |
