摘　　要：采用SEM和金相显微镜研究了在纯锌浴中加Ti元素对含硅钢热浸镀锌的影响。结果表明,随着锌浴中Ti含量的增加,Ti对ζ相生长的抑制作用增强,合金层厚度逐渐减薄,Ti能有效地抑制含硅活性钢镀层的超厚生长。当锌浴中Ti元素含量大于0.05%时,镀层中出现Γ2粒子。锌浴中添加0.03%-0.05%Ti时,能完全抑制含0.09%S i钢在常规热浸镀锌时的圣德林效应。但对于含0.36%S i钢,钛的作用不明显。The effect of Ti added in Zn bath on HDG（ Hot Dip Galvanizing） process of steel plate was studied using SEM. The results show that, when the titanium content in the zinc bath increased, the growth of ζ phase in coating was restrained distinctly, the thickness of coating decreased. Titanium can effectively restrain the excess growth of coating for reactive steel containing silicon during the hot dip galvanizing process. When the titanium content in the zinc bath was over 0.05%, the F2 phase particles were formed in the coating. Adding 0.03% - 0.05% Ti to Zn bath for 0.09% Si steel could completely restrain the Sandelin effect. But adding titanium to the zinc bath had no effect on the 0.36% Si steel.
