分析了铸造合金颗粒复合材料中增强相（ＳｉＣ颗粒）与基体（铸铁）界面结合的形态及影响因素、界面结合机制和稳定性，提出了改善界面结合状态的方法．在实验室条件下，采用离心铸造工艺制取铁基／ＳｉＣ颗粒复合材料，通过金相分析和电子探针等测试手段．研究了经不同的高温处理后铁基／ＳｉＣ颗粒复合材料界面变化规律． The morphology and influential factors of interfacial bonding between SiC particles and matrix (cast iron), the bonding mechanism and the stability of interface were analyzed. The methods to improve the interfacial bonding state were put forward. Under laboratory conditions, the centrifugal casting process was used to prepare iron-based / SiC composite materials, which were tested by means of metallographic analysis and electron probe. The changes of interface of Fe-based / SiC particle composites after different heat treatment were studied.
