SiC_p/Al复合材料的自浸渗工艺

The Spontaneous Infiltration Process for SiCp/Al Composite

研究了在大气条件下制备碳化硅颗粒增强铝基复合材料的新方法该方法以Ｋ２ＴｉＦ６为助渗剂，使其与碳化硅颗粒均匀混合，在浸渗用的铸模中制成混合体，由液态铝或其合金自动浸渗。

In this paper, a new method of making aluminium matrix SiC partical reinforced composite by spontaneous infiltration in air without additional pressure or vaccum is described This method uses K2TiF6 as infiltration promoter It is mixed fully with SiC partical The mixed body is made in infiltration die Aluminium matrix composite reinforced with SiC partical is made by liquid Al or its alloy infiltrating spontanously The influence of technology factors on the process is analyzed Feasibility of manufacturing SiCp/Al composite is pointed out The mechanism of spontanous infiltration is discussed
