海上平台阴极保护原位监测系统

在渤西APP平台上预设了微机化阴极保护原位监测系统,这在我国尚属首例。该系统由微机自动数据采集存储器、数据传输系统和探头群3部分组成。从导管架下水开始,全方位监测了导管架电位分布,阳极工作电位和发出电流的经时变化,获得了导管架在阴极保护下极化过程全面完整的信息。

ELECTROCHEMICAL MEASUREMENT OF STEEL CORROSION IN SEABOTTOM SEDIMENT WITH “MD” METHOD

The tbough one year cormsion potential and polarisation resistanoc for 3 kinds of stals in seabottomedment of Liaodong Bay were measured with the “MD” method.The measurements wiIl have some thoretical and pndital talues. The thooretical valoc lies in thatthe reoorded changing process of the practital corrosion case can be basis for indoor discussion andeectrochemical on the corrosion practical value lies in that the obtained datu canbe basis for designing and controlling elatrochemical protation syttems. In fact, it is very difficult tomeasure in situ the cornosion parnders of steeIs in sea sediment.

钢在海洋沉积物中的腐蚀研究——Ⅰ.“移植埋片法”(MD)实海腐蚀电化学测量研究

海洋沉积物俗称海底土,海洋沉积物腐蚀学系海洋腐蚀科学中的新学科,一些资料表明,钢在海底土中的腐蚀程度要比在海水区、潮差区、飞溅区低(友野理平,1976;冈本刚,1977),这些资料(Schumecher,1979)是通过近海钢结构的观察和采用打入浅海中的试验钢桩取得的,但由于宏观电池的作用,它们不能反映单独埋在海土中钢的腐蚀情况。实际海土中的腐蚀是相当复杂的,由于这项研究难度高,耗资大。
