摘　　要：用扫描电镜、动态接触角测量仪、拉压试验机等,对不同表面处理镁合金的表面形貌和特性、玻璃纤维增强树脂/镁合金叠层板(GFRR/Mg)的界面形貌和力学性能进行分析。结果表明:表面处理可提高镁合金表面能和GFRR/Mg叠层板的力学性能。经磷酸盐处理和高锰酸盐处理后,镁合金的表面能分别为85.97 mJ/m^2和92.04 mJ/m^2,比打磨处理增加了53.7%和64.6%,表面润湿性明显改善。磷酸盐和高锰酸盐处理镁合金制备的GFRR/Mg叠层板界面结合良好,抗拉强度和弯曲强度比打磨处理的GFRR/Mg叠层板稍高。The surface morphology and characteristics of treated magnesium alloy,and the interface morphology and mechanical properties of glass fiber reinforced resin/magnesium laminate(GFRR/Mg)were analyzed by SEM,dynamic contact angle measuring instrument and universal testing machine.The results show that the surface energy of magnesium alloy and the mechanical properties of GFRR/Mg laminate can be improved by surface treatment.The surface energies of magnesium alloy treated with phosphate and permanganate are 85.97 mJ/m^2 and 92.04 mJ/m^2,respectively,which are improved by 53.7%and64.6%compared with the magnesium alloy treated with abrasion-only.The surface wettability of magnesium alloy is obviously improved by phosphate and permanganate.The GFRR/Mg laminate prepared by magnesium alloy treated with phosphate and permanganate has very tight bonding,and tensile strength and bending strength are slightly higher than those of GFRR/Mg laminate treated with abrasion-only.
