| 摘要: |
| 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;岡本刚,1977),这些资料(Schumacher,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。实际海士中的腐蚀是相当复杂的,由于这项研究难度高,耗资大,因而至今报道很少(Schmidt,1982) 随着科学技术的发展,海底工程设计急需海底土的腐蚀资料,作者在确保海土结构不变的前题下,首创了“移植埋片法(MD)”,对3种海洋用钢在海土中的腐蚀电位和极化阻力进行了海上测量,为海洋沉积物腐蚀学的研究开辟了新途径,同时对海底钢铁工程的防腐设计提供了依据。 |

| Abstract: |
| With the developement of science and technology, steel corrosion data onsubmarine sediment is urgently needed for submarine engineering design. The author, for the purpose of not disturbing sediment, invented a methed called “corroded electrochemical measurement of marine deposit (MD)”.This paper disccusses the corrosion process and variation rule of three kinds of steel with the MD mothed based on the measured of corrosion voltage and polarization resistance. |
| Key words: steel corrosion,MD, |
