摘要
Abstract
[Objective]To match marine environment investigation in the Eastern of the South China Sea,this article studied corrosion of stainless steel fasteners used for ocean dynamic environment monitoring system in the sea area.[Methods]Using austenite stainless steel fas-teners,fastening equipment on steel pile of offshore platform and stainless steel cable, through sea trials a year,to check this type of corrosion of stainless steel fasteners.[Results]Serious corrosion effect of stainless steel fasteners was found,corrosion of materials of differ-ent shapes had different position and levels.Corrosion of stainless steels characterized by lo-calized corrosion such as pitting and crevice corrosion,perforation and fracture failure severe-ly.[Conclusion]To ensure the same electrode potential of the materials,and reduce the for-mation of the macro cell,it suggests that the grades and the batches of the same metal mate-rials should be used in the marine metal structure;If you do need to use dissimilar metals,you must to electrical insulation between dissimilar materials.关键词
