Effect of Carbon Nanoparticle Content on Machinability and Wettability of Carbon/Silicon Carbide Ceramics

Keywords： Cp/SiC ceramics , machinability , wettability

采用无压烧结法制备纳米碳颗粒(nano-Cp)改性碳化硅陶瓷(Cp/SiC),研究了不同纳米碳含量对Cp/SiC陶瓷的机械加工性及与玻璃熔体润湿性的影响.通过XRD和SEM对Cp/SiC陶瓷进行物相和显微分析.研究结果表明:随着可加工相纳米碳含量的增加,Cp/SiC陶瓷的机械加工性能得到明显改善.根据陶瓷材料的机械加工指数(M)综合评价,M15=0.921＞ M25=0.547＞M5=0.056＞ M0=0.021(下标数字代表碳含量),且15wt％Cp/SiC中的碳颗粒预先被氧化,抑制了Cp/SiC陶瓷基体表面形成SiO2,阻止了Cp/SiC陶瓷与玻璃熔体的润湿,使夹具材料与玻璃熔体不发生粘接,适合用作玻璃夹具材料.
