| 摘 要： | 通过正交实验确定了2024铝合金表面化学镀镍合金层的镀液组成,并通过扫描电镜对镀层的表面形貌进行了观察,通过交流阻抗对镀层在3.5%NaCl溶液的耐蚀性进行了测试。实验结果表明,采用本溶液组成和工艺可以制备表面均匀平整、致密的Ni-P合金层,镀层与基体结合良好。同时,镀层的显微硬度约是基体的8.5倍,耐蚀性得到明显改善,具有良好的工业应用前景。

| Abstract: | The bath composition of electroless plating Ni-P coating for 2024 aluminum alloy was studied using orthogonal experiment.The surface morphology was observed by scanning electron microscopy(SEM),and the corrosion resistance of Ni-P films was investigated by means of electrochemical impedance spectroscopy(EIS).The results show a compact and homogeneous coating with a good adhesion can be obtained by the bath.The microhardness of Ni-P coatings is 8.5 times greater than that of aluminum alloy,and the corrosion ... |
