摘    要:应用SEM,EPMA等方法研究了锌浴中镍含量对热浸锌镀层厚度的影响,试验结果表明,当锌浴中镍含量小于0.12%(wt)时,镀层随镍含量增加而减薄,当镍含量大于0.12%时,镀层则随镍含量增加而增厚,在热镀锌生产线上对0.10%以下的不同镍含量锌浴的应用结果表明,为了兼顾不同产品对最低镀层厚度的要求,镍含量可在0.04%-0.10%间选择,这时由于减少镀层超厚,节锌效果明显。

关 键 词:热浸镀锌  热浸锌  镍合金镀层  锌层厚度

Abstract:The effect of Ni content in Zn bath on thickness of hot dip galvanized coating was studied using SEM. It showed thatwith the Ni content increasingthe coating thickness increased when the nickel content < 0.12 %,and then decreased when Ni content >0.12%. The industrial practice showed that the Ni content can be chosen in a range of 0.04%~0.10%which results in satisfactory coating thickness and saves zinc because of reducing the excess coating thickness.
