以Ni（CO）4为前驱体，通过羰基金属化学气相沉积工艺在碳纤维表面沉积连续镍膜，从而制得镍覆膜碳纤维材料。实验给出了镍覆膜碳纤维的较佳制备工艺条件。借助SEM、EDX、XRD、冷热循环实验、断裂强度分析、差热分析等多种分析测试手段研究了镍覆膜碳纤维的性能。结果表明碳纤维表面沉积的膜层为纯镍相，连续致密，与碳纤维基底结合良好，可经受4次冷热循环而不脱落；碳纤维表面沉积连续镍膜后，其断裂强度提高了34．9％；差热分析显示沉积连续镍膜后可有效提高碳纤维的抗氧化性能。

A dense and smooth nickel-coated film on the surface of carbon fiber was obtained by using metal or ganic chemical vapor deposition （MOCVD） process with carbonyl nickel as precursor. The as-received coating film was pure nickel without any impurities. The influence of deposition temperature on nickel-coated film was investigated and the results showed that the ideal nickel-coated film could be obtained at temperature of 270℃. The measurement of adhesive force of nickel-coated film with carbon fiber was performed by thermal-cold cyc- ling testing, the coating film exfoliation didn＇t appear until four times of thermal-cold cycling. The fracture strength of nickel-coated film carbon fiber increased by 34.9% compared to that of original carbon fiber. Differ- ential thermal analysis testing indicated that the coating film could enhance the property of oxidation resistant of carbon fiber.
