| 摘 要： | 以氧化处理的SiCp为增强体,Al-10Si-0.5Mg为基体,采用压渗法制备SiCp/Al复合材料,对复合材料预氧化的研究结果表明：在相同的保温时间下,SiC颗粒的氧化量和氧化层厚度都随氧化温度升高而增加,并且适度的预氧化可以提高界面结合强度,复合材料抗拉强度可达645MPa,但其韧性稍有下降.

| Abstract: | Investigation on the SiCp oxidation at elevated temperature and the mechanical properties of the preoxidation SiC reinforced Al-10Si-0.5Mg Aluminum composites produced by pressure infiltration process shows that the oxidation increment of SiCp, the dependence of the volume fraction and that of the thickness of SiO2 layer increase with the oxidation temperature at the same oxidation time; and the ultimate tensile strength of the composites can be improved as a result of the appropriate thickness of the oxidation layer, however the toughness will be fall some little. |
