研究了氧化态和原始态碳化硅颗粒增强铝基复合材料的界面结构及其对复合材料弯曲强度的影啊。结果发现．氧化处理后碳化硅与基体铝界面上有一ＳｉＯ２非晶层，该非晶层内由于铝的扩散作用而形成铝的浓度梯度。原始态碳化硅与铝的界面上则无此非晶层．由于此非晶层的作用．导致界面结合强度的提高从而增加了复合材料的弯曲强度。
The interfacial structure between the oxidized state and the original SiC particle reinforced Al matrix composites and their influence on the flexural strength of the composites were investigated. turn out. After oxidation treatment, there is an SiO2 amorphous layer on the interface between the silicon carbide and the matrix aluminum, and the aluminum concentration gradient is formed in the amorphous layer due to the diffusion of aluminum. The original state of silicon carbide and aluminum interface is no such amorphous layer. Due to the effect of this amorphous layer. Resulting in an increase in the bonding strength of the interface, thereby increasing the bending strength of the composite material.
