摘要:
为了同时改善碳纤维与金属铝基体之间的润湿性和分散性，采用化学复合镀的方法在碳纤维上制备Ni-P-SiC复合镀层。通过扫描电子显微镜观察镀层表面和截面形貌，通过单纤维电子强力测试仪分析Ni-P镀层和Ni-P-SiC镀层力学性能，采用同步热分析仪分析Ni-P镀层和Ni-P-SiC镀层的氧化性能。结果表明：Ni-P-SiC镀层的抗拉强度比Ni-P镀层的抗拉强度稍低，但Ni-P-SiC镀层的形状参数m对比Ni-P的形状参数m提高了8.45%，材料的可靠性提高;对比出现最大放热峰的温度，Ni-P-SiC镀层比Ni-P镀层的出现温度高130℃，Ni-P-SiC镀层的抗氧化性明显提高；通过Ni-P-SiC镀层改性后的碳纤维在铝基中分散性明显提高，减少了碳纤维的聚集。Ni-P-SiC镀层有效解决了高温条件下碳纤维与铝基复合的难题。

Abstract:
In order to improve the wettability and dispersion of carbon fibers in aluminium substrate, Ni-P-SiC coating was prepared on carbon fiber by electroless composite plating. The surface and cross-sectional morphologies of the coating were observed by scanning electron microscopy (SEM). Mechanical properties of the Ni-P coating and Ni-P-SiC coating were measured by single fiber electronic tensile strength tester. Oxidation resistance of the Ni-P coating and Ni-P-SiC coating were investigated by synchronous thermal analyzer. Results show that the tensile strength of Ni-P-SiC coating is weaker than that of Ni-P coating, while the shape parameter of Ni-P-SiC coating, m, is increased by 8.45%. The reliability of the Ni-P-SiC coating is improved. The temperature of largest exothermic peak of Ni-P-SiC coating is 130℃ higher than that of Ni-P coating, which indicates that the oxidation resistance of carbon fiber in Ni-P-SiC coating is significantly improved after electroless composite plating. Besides, the dispersion of Ni-P-SiC-coated carbon fibers in the aluminium substrate is significantly improved, decreasing the aggregation of carbon fiber. Ni-P-SiC coating effectively solves the problem of composition between carbon and aluminum substrate in high temperature.
