介绍了一种在碳纤维上制备SiC涂层的方法。SiC涂层是由一氧化硅（SiO）与沉积在纤维上的热解碳（PyC）层反应生成的。讨论了保温时间对SiC层微观结构的影响。比较了未涂层和SiC涂层碳纤维的氧化行为。分析了SiC涂层的形成机理。随着反应时间的延长，SiC涂层变厚，表面变得粗糙。SiC涂层提高了碳纤维的抗氧化性能。SiC涂层碳纤维的起始氧化温度比未涂层碳纤维的起始氧化温度高约200°C。SiC涂层的生长主要归因于SiO/SiC/C体系中SiO与PyC的间接反应，其中Si被认为是关键的中间产物。
A method for preparing a SiC coating on carbon fibers is presented. The SiC coating was generated from the reaction of silicon monoxide (SiO) with a pyrolytic carbon (PyC) layer deposited on the fibers. The influence of holding time on the microstructure of the SiC layer was discussed. The oxidation behaviors of the uncoated and SiC coated carbon fibers were compared. The formation mechanism of the SiC coating was evaluated. With increased reaction time, the SiC coating becomes thicker and its surface becomes rough. The oxidation resistance of the carbon fiber was improved by the SiC coating. The initial oxidation temperature of the SiC coated carbon fiber is about 200°C higher than that of the uncoated carbon fiber. The growth of the SiC coating is mainly attributed to the indirect reactions of SiO with PyC in the SiO/SiC/C system, in which silicon is considered a critical intermediate product.
