新型钛铜复合管在流动海水中的腐蚀行为

摘要

设计了循环管路,通过海水管路冲刷腐蚀试验,对比研究了新研制的爆炸焊钛铜复合管与铜管的耐海水腐蚀性能.宏观和微观腐蚀形貌以及微观成分分析表明,在海水冲刷作用下,铜管受到腐蚀,微观表面呈现颗粒状形貌,钛铜复合管无腐蚀,表现出了良好的应用性能.%Cycle pipeline of Ti-Cu composite pipes and Cu pipes were assembled for flowing seawater test. Anti-corrosion properties of Ti-Cu composite pipes by explosive welding and Cu pipes in flowing seawater were studied. Macroscopic and microscopic corrosion morphology and microscopic components analysis showed that, after flowing seawater test, Ti-Cu composite pipe isn' t corroded; however, Cu pipe is corroded and its microscopic corrosion morphology is granule. It was concluded that the applied performance of Ti-Cu composite pipes is better.
