摘要
采用局部熔覆法复合水/化学氧化法对碳纤维(CF)表面Al涂层的制备及氧化工艺进行了研究,并采用扫描电子显微镜(SEM)、X-射线能谱仪(EDS)和X-射线衍射仪(XRD)等对CF表面涂层的微观形貌和物相组成进行了表征.研究表明:采用局部熔覆法可以制备得到Al涂层,当拉丝速度为10mm/s时涂层表面形貌优良,能够实现对基体CF的完全包覆;当熔覆次数由1次增加至3次时获得的涂层致密均匀,厚度由0.8μm增加至3.1μm;研究还发现采用水氧化法可以实现Al涂层向Al_2O_3的转变,而采用化学氧化法时,CF表面的Al涂层存在大量溶解的现象.
In this experiment,the preparation and oxidation process of Al coating on carbon fiber(CF)surface were studied by the method of partial cladding combined water/chemical oxidation method.The microstructure and phase composition of CF surface coatings were characterized by scanning electron microscopy(SEM),X ray energy dispersive spectroscopy(EDS)and X ray diffraction(XRD).The results show that the Al coating can be prepared by partial cladding.When the control drawing speed is10mm/s,the surface morphology of the coating is good,and the coating of the matrix CF can be completely coated.When the cladding times increased from1time to3times,the coating was compact and uniform,and the thickness increased from0.8渭m to3.1渭m.It is also found that the Al coating can be transformed into Al2O3by water oxidation method,but the Al coating on the surface of CF has a large number of dissolution phenomena by chemical oxidation method.
