An lnvestigation on of Galvanic Corrosion between Exhaust System of Titanium Alloy and Hull Steel

摘要: 研究了TA28、Ti6321钛合金以及921A、907A船体结构钢在海水环境中的腐蚀特性及电化学行为,对两种钛合金与船体钢之间多面积比条件下的电偶腐蚀行为进行了试验。结果表明,当钛合金与钢直接接触时,钛合金与钢制船体间存在轻微的电偶腐蚀,采用电绝缘措施可以有效控制钛合金对钢制船体的电偶腐蚀。

Abstract: Corrosion and electrochemical characters of titanium alloys TA28 and Ti6321 as well as ship hull steels 907A and 921A,which are employed in ship,were studied by using electrochemical methods. Experiment was carried out to investigate galvanic corrosion behavior between titanium alloys and ship hull steels in different area ratio. Resultsshow that slight galvanic corrosion would occur on ship hull when TA28 or Ti6321 are used,while a proper insolating can effectively control the galvanic corrosion between titanium alloys and ship hull steel.
