第三代汽车钢表面合金镀层的性能
Properties of Alloy Coatings on Surface of the Third Generation Automotive Steel
摘 要
采用热浸镀方法在第三代汽车钢表面制备了3种不同组分的合金镀层，研究了Al含量和Si元素添加对合金镀层物相组成、显微组织、显微硬度、耐腐蚀性能的影响。结果表明：Zn-0.6Al-1.6Mg、Zn-1.8Al-1.6Mg和Zn-1.8Al-1.6Mg-0.25Si合金镀层的主要物相都为Zn、Al和MgZn2，在Zn-1.8Al-1.6Mg-0.25Si合金镀层中还出现了黑色的针状Mg2Si相，增加Al含量和添加Si元素后，合金镀层的晶粒更加细小、组织均匀性提高；Zn-0.6Al-1.6Mg、Zn-1.8Al-1.6Mg和Zn-1.8Al-1.6Mg-0.25Si合金镀层的显微硬度分别为164.5、186.1、195.4 HV，不同组分的合金镀层的耐腐蚀性能从高至低顺序为Zn-1.8Al-1.6Mg-0.25Si > Zn-1.8Al-1.6Mg > Zn-0.6Al-1.6Mg，在合金镀层中增加Al含量或者添加Si元素都有助于提升合金镀层的显微硬度和耐腐蚀性能。

Abstract
Three kinds of alloy coatings with different components were prepared on the surface of the third generation automobile steel by hot dip plating. The effects of Al content and Si addition on the phase composition, microstructure, micro-hardness, corrosion resistance of the coatings were studied. The results show that the main phases of Zn-0.6Al-1.6Mg, Zn-1.8Al-1.6Mg and Zn-1.8Al-1.6Mg-0.25Si alloy coatings were Zn, Al and MgZn2, and black needle-like MgSi2 phase also appeared in the Zn-1.8Al-1.6Mg-0.25Si coating. With the increase of Al content and Si addition, the grain size of the coatings was finer, and the structure uniformity of the coatings was improved. The microhardness of Zn-0.6Al-1.6Mg, Zn-1.8Al-1.6Mg and Zn-1.8Al-1.6Mg-0.25Si alloy coatings were 164.5, 186.1, 195.4 HV, respectively. The corrosion resistance of the alloy coatings with different composition from high to low was in the order of Zn-1.8Al-1.6Mg-0.25Si>Zn-1.8Al-1.6Mg>Zn-0.6Al-1.6Mg. The increase of Al content and Si addition in the coatings were helpful to increase the micro-hardness and corrosion resistance of the coatings.
