镀层合金与碳钢基底的电偶腐蚀研究
Galvanic Corrosion Study of Surface Coating and Steel Substrate
摘要
Abstract
Objective]In this paper,in order to study whether the polarity reversal phenome-non is occurred after the damage of the hot-dipped coating.[Methods]The coupling electrodes were composed of Zn-55%Al-1.6%Si alloy,or Zn-5%Al-0.2%RE and alloyed with carbon steel.The galvanic current was tested in natural seawater and medium with different Cl-concentrations to study the possibility of polarity reversals.[Results]The experimental re-sults show that the galvanic couple composed with two kinds of coating alloys and carbon steel did not occur the polarity reversal phenomenon in all the experimental conditions.[Con-clusion]The coupling current value of the galvanic couple composed with the same coating al-loy and carbon steel was different in different Cl- concentrations medium.With the increase of the Cl- concentration,the coupling current was increased.关键词
