摘　　要：采用电镀法在碳纤维表面沉积一层纯Ni镀层,然后将纤维剪短,采用化学镀法使短纤维表面以及两端包覆一层Ni-P合金镀层,并使纤维表面金属层加厚,来满足保护纤维的需要。通过不同正交体系研究碳纤维增重率,得到了优化的镀镍工艺。观察了镀层的表面形貌,测试了镀层的结合力,并对镀层的成分进行了分析。结果表明,纤维表面镀层均匀、致密、表面光亮和结合力强;电镀获得了纯Ni镀层,而复合镀获得了Ni-P合金镀层。Electroplating Ni on carbon fiber surface,and then shorter the fiber and subsequently chemical plating Ni-P alloy coating on the surface of carbon fiber to meet the requirement for the protection of the fiber.The optimum nickel plating process were obtained by orthogonal experiment.The surface morphology of the carbon fiber was observed and the adhesion strength of the coating was tested.The chemical composition of the coating was measured.The results show that the nickel deposite of carbon fiber obtained by the method is uniform,compact and adhesive.The electroplating can obtain pure Ni coating,but the composite plating can obtain Ni-P alloy coating.
