摘　　要：在聚酰亚胺(PI)纤维表面化学镀镍–磷合金镀层。采用场发射扫描电子显微镜、能谱仪、X射线衍射仪、微电阻测试仪等表征了其微观形貌、成分、物相组成和导电性。分别通过铜盐加速乙酸盐雾(CASS)试验和冷热循环试验对镍–磷镀层的耐蚀性和结合力进行评判。结果表明:聚酰亚胺纤维化学镀镍–磷后,表面沉积了一层均匀、致密的镍–磷合金镀层,其中镍和磷的质量分数分别为88.32%和8.41%,厚度约为2μm。镀层与纤维结合良好,导电性和耐蚀性优异。Ni-P alloy coating was obtained on the surface of polyimide （PI） fiber by electroless plating. The microscopic morphology, composition, phase structure and conductivity of the electroless NiP plated PI fiber were characterized by field emission scanning electron microscope, energy-dispersive spectrometer, X-ray diffractometer and micro-resistance tester. The corrosion resistance and adhesion strength of Ni-P coating were evaluated through copper accelerated salt spray （CASS） test and heating-cooling cycle test, respectively. The results showed that a uniform and compact NiP coating composed of 88.32wt% nickel and 8.41wt% phosphorus with a thickness of 2 μm was obtained on PI fiber surface after electroless plating. The Ni-P coating bonds strongly to the fiber and features excellent conductivity and corrosion resistance.
