摘要:
采用真空反应浸渗法,分别以碳纤维/树脂碳(C/C)、碳纤维(Cf)、石墨(Graphite)、玻璃碳(GC)为基体碳制备了C/Cu复合材料。利用OM、XRD、SEM、EDX等检测分析方法研究了基体碳种类对C/Cu复合材料浸润行为以及界面层微观组织的影响。结果表明:Cf和C/C与Cu-Ti合金基体润湿性较好,接触角分别为56.26°和40.12°,而Graphite和GC与Cu-Ti合金基体不润湿,接触角均大于90°;Cu-Ti合金与Cf、C/C良好的润湿性源于熔渗过程中C原子在TixCuy相中反应扩散所生成的TiC界面层能够较好的与C相和Cu润湿,从而有效改善了C/Cu界面润湿性和界面结合状态;其中,基体碳为Cf时所生成的TiC界面层厚度最大,且致密均匀;综合考虑基体碳与Cu-Ti合金的润湿行为及界面层组织,四种碳基体的优劣顺序为:Cf > C/C > Graphite > GC。
Abstract:
The vacuum reaction infiltration method was used to prepare C / Cu composites with carbon fiber/resin carbon (C/C), carbon fiber (Cf), graphite (Graphite), and glassy carbon (GC) as matrix carbon. The OM, XRD, SEM, EDX and other detection and analysis methods were used to study the influence of different matrix carbon on the wetting behavior of C/Cu composites and the microstructure of the interface la<x>yer. The results show that C/C and Cf had good wettability with Cu-Ti alloy, and the contact angles were 56.26 ° and 40.12 °, respectively. However, Graphite and GC did not wet with Cu-Ti alloy, and the contact angles were both larger than 90 °. The good wettability between Cu-Ti alloy and C/C、Cf is mainly because that the TiC la<x>yer which is formed by reaction-diffusion during the vacuum reaction infiltration can be wetted well with C and Cu, improving the C/Cu interface wettability and interface bonding state. The TiC interface la<x>yer was dense and uniform, and had the largest thickness when the matrix carbon is Cf. Finally, by considering the wetting behavior and the interface la<x>yer microstructure, the order of precedence for different carbon matrix is as follows : Cf > C/C > Graphite > GC.
