| 摘 要： | 利用有机前驱体浸渍法制备了Si3N4网络陶瓷预制体,利用液态金属浸渗法制备出Al基、Mg基复合材料：分析了在浸渗过程中浸渗温度、润湿角、浸渗时间、浸渗高度的相互关系。在压力下金属液克服浸渗阻力．使浸渗得以完成。网络陶瓷骨架孔筋表面覆盖一层氧化膜有利于自发娄渗的进行。合金中适量镁元素的存在使平面上发生轻微化学放热反应．对浸渗有利。指出压力浸渗制备铝基复合材料与无压浸渗制备镁基合材料的特点。探计了这种复合材料抗压强度和摩擦磨损性能特点。指出Si3N4／Al复合材料，Si3N4/Mg复合材料抗磨擦性能明显优于基休．抗拉强度大大高于基体。

| Abstract: | One Si3N4 ceramic perform has been fabricated by precursor immersing methods. One Si3N4/Al, Si3N4/Mg interpenetrating phase composites were fabricated via pressure infiltration and pressureless infiltration technology. Infiltration temperature and infiltration time have some influences to infiltration behavior. The oxidizing film coated on the ceramic strut and Mg element in melt have beneficial to infiltration. A light chemical reaction in the Si3N4/Al, Si3N4/Mg interface made the infiltration to be succeeded. The properties of composites,such as compressive strength and wear-resistance,excel greatly the matrix. |
