摘要:

采用热浸镀的方法在镀锌模拟器上制备得到纯Zn、Galfan和Zn-Al-Mg 3种锌合金镀层钢板,3种镀层中的合金元素质量分数分别为Zn-0.2%Al,Zn-5%Al和Zn-2%Al-2%Mg,镀层钢板为无间隙原子钢 (IF钢)。采用全浸泡的方法研究了3种锌基合金镀层钢板的腐蚀行为,并采用电化学方法和扫描电镜研究了浸泡不同时间的锌基合金镀层钢板的耐蚀性。结果表明,在浸泡初期,Zn-Al-Mg镀层钢板的自腐蚀电流密度最大;随着浸泡时间延长,Zn-Al-Mg镀层钢板的自腐蚀电流密度缓慢减小,而纯Zn镀层钢板和Galfan镀层钢板的自腐蚀电流密度均增大。Galfan镀层钢板的Nyquist曲线具有明显扩散特征,镀层表面的腐蚀速率较快;而Zn-Al-Mg镀层钢板的Nyquist曲线表现为有限扩散特征,这表明其表面覆盖的腐蚀产物提高了Zn-Al-Mg镀层钢板的耐蚀性。

Abstract：

Three hot-dip galvanizing coatings i.e. pure Zn, Zn-5%Al and Zn-2%Al-2%Mg were prepared respectively on sheets of a commercial interstitial free (IF) steel by a hot-dip process simulator (HDPS). Corrosion behavior of the coated steel sheets was studied by means of immersion test, electrochemical measurement and scanning electron microscope (SEM). Results show that the Zn-Al-Mg coating has the largest corrosion current density at the early stage of immersion. While with the increasing immersion time, the corrosion current density of the Zn-Al-Mg decreases but those of the pure Zn and Zn-5%Al coatings increase. For the Zn-5%Al coating, diffusion characteristics could be found for its Nyquist curve, which means higher corrosion rate. However, for the Zn-Al-Mg coating, limited diffusion characteristics could be found for its Nyquist curve, which means a perfect coverage of corrosion products on the coating surface, in other word, the corrosion resistance was enhanced.

Key words： steel sheet Zn-Al-Mg coating corrosion resistance Galfan coating hot-dipping
