镁合金表面功能纳米薄膜的制备

Preparation of Functional Nano-film on the Surface of Magnesium Alloy

摘要:

通过有机镀膜技术，对镁合金表面进行改性。对有机镀膜处理后的镁合金表面的接触角，表面自由能进行了测定。研究了不同有机镀液，在恒电流作用下，有机镀膜时间对镁合金表面性能的影响。结果表明，经过TTN溶液有机镀膜后，镁合金板表现出亲水性，其表面能比未处理镁合金板的表面自由能要高；而经过DHN和DAN溶液有机镀膜后，镁合金板表现出良好的疏水性，其表面能比未处理镁合金板的表面自由能要低，在二者中DHN处理后的疏水效果最好。实现了对镁合金表面疏水、亲水表面改性，能够很好的扩大镁合金在工业中的应用领域。

Abstract:

A new technology named polymer plating for surface modifcation of magnesium alloys has been developed. After being polymer-plated, the surface condition of the plates has been investigated through contact angle and surface energy. Compared with untreated plates, plates treated with TTN solvent possess hydrophilicity due to its higher surface energy and lower contact angle. Plates treated with DHN or DAN solvent have lower surface free energy and higher contact angle than untreated plate. A method that can fabricate hydrophilic or hydrophobic films with different solvents by polymer plating is obtained.
