| 摘 要： | 本文采用X射线光电子谱(XPS)和俄歇能谱技术(AES)对原始SiC颗粒表面和粉末冶金法制备的SiCP/Al复合材料界面的化学状态进行了研究.结果表明:原始SiC颗粒表面主要存在SiC、SiO2、游离C、吸附氧、Fe2O3等;SiCP/Al复合材料界面存在Mg偏聚和氧元素.由热力学分析可知,Mg元素能够向界面偏聚,并可能与界面处的氧反应生成MgO.

| Abstract: | The chemical states of both the original surface of SiC particles and the interface of SiCP/Al composite made by powder metallurgy were investigated by means of XPS and AES.It was found that there are SiC,SiO2,free carbon,absorption oxygen and Fe2O3 on the original surface of SiC particles and segregated Mg and oxygen element in the interface of SiCP/Al composite.According to thermodynamichs,it is possible that Mg element segregated on the interface reacts with oxygen,yielding MgO. |
