摘要
研究了锌液中0.1%~0.5%(质量分数)Mn对X80钢表面润湿行为的影响。采用改良座滴法获得了450℃时Zn-Mn合金的接触角,通过SEM/EDS观察分析样品表面及界面的组织结构,研究了Zn-χMn(χ=0.1~0.5)合金与X80钢基板的润湿行为和界面反应。结果表明:锰元素对锌合金与钢基体间的润湿性反应起到正吸附作用。在450℃时,当熔体中的锰含量为0.1~0.5时,Zn-χMn合金与钢基间的润湿接触角从85°减小到62°。锌合金熔体/X80钢属于反应性润湿体系,生成的界面产物由FeZn_(10)(δ)、FeZn_(13)(ζ)和Fe_(3)Zn_(10)(Γ)/Fe_(5)Zn_(21)(Γ1)相组成,润湿行为受锌合金界面反应影响。在铺展三相线前沿存在前驱膜,前驱膜的出现能够促进润湿。
The effect of the addition of Mn in the range of 0.1%~0.5%(mass fraction)in molten Zn-Mn alloys at 450℃on the surface wetting behavior of X80 steel was studied by means of contact angle measurement with an improved sessile drop method and microstructure observation with SEM-EDS in terms especially of the interaction at interface molten Zn-χMn(χ=0.1~0.5)alloys/X80 steel substrate.The results show that Mn can play a positive role in the wettability between the molten Zn alloy and the steel.At 450℃,with the increasing Mn content from 0.1 to 0.5,the wetting contact angle between the molten Zn-χMn alloy and the steel decreases from 85°to 62°.The molten Zn alloy/X80 steel belongs to the reactive wetting system,correspondingly,the interface reaction may result in interface products composed of FeZn_(10)(δ),FeZn_(13)(ζ)and Fe_(3)Zn_(10)(Γ)/Fe_(5)Zn_(21)(Γ1)phases.Therefore,the wetting behavior is affected by the interface reaction.There is a precursor film emerged at the front of the three-phase line,which can enhance the wettability of the molten Zn alloy to X80 steel.
