| 摘 要： | 采用高能球磨技术制备SiC和Al的复合粉末,研究了球磨时间、过程控制剂(PCA)、球料比以及SiC与Al混粉质量比对复合粉末粒度和包覆效果的影响。结果表明,复合粉末平均粒径的大小与PCA、混粉比、球磨时间和球料比有关,其影响程度依次为:PCA>混粉比>时间>球料比;复合粉末的粒径大小随着球磨时间、PCA和球料比的增加而显著减小,而随着混粉质量比的增加呈现先减后增的趋势。混粉质量比为3:7的复合粉末平均粒径达到最小值;球磨时间为9h、PCA添加量为1.5%、球料比为12:1和Al与SiC混粉质量比为3:7时,能制备出颗粒细小、包覆效果好的优质复合粉末。

| Abstract: | SiC/Al composite powder was prepared by high energy ball milling,and effects of milling time,process control agent(PCA),the weight ratio of ball to powder as well as quantity ratio of SiC to Al on the granularity of composite powder and the cladding effects of Al on SiC were investigated.The results show that the average granularity size of composite powder is closely related to the PCA,the quantity ratio of SiC to Al,ball milling time,and the weight ratio of ball to powder,and influencing order is as follo... |
