SiCp/Al复合材料无压自浸透工艺

The Pressless Infiltration Process for SiCp/Al Composite

摘要: 研究了用K₂ZrF₆作为助浸剂与SiCp进行混合的工艺,实现用无压自浸透的工艺制造SiCp/Al复合材料。结果表明,直接混合工艺比K₂ZrF₆水处理工艺简便,并易于控制K₂ZrF₆的用量,K₂ZrF₆与SiC混合后,能明显提高SiC颗粒和Al液的湿润性。

Abstract: The experiment of mixing K₂ZrF₆, a wetting Promotor, with SiCp to fabricate SiCp/Al composites via preesless infiltration process is conducted. It indicates that this pressless infiltration process is simpler than the process of solution pretreatment, the amount of K₂ZrF₆ can be easily controlled, and the wettability between SiC and Al is greatly improved by mixing SiC with K₂ZrF₆.
