摘要
超细氧化铝粉体经预处理后作为增强相,采用超声波对其进行化学镀铜,利用粉末冶金技术制备了氧化铝增强铜基复合材料。采用X射线衍射仪(XRD)、扫描电镜(SEM)、能谱分析仪(EDX)等手段对试样进行了观察分析。结果表明,氧化铝弥散强化镀铜后的复合粉体基本上呈均匀分布。同时,不同烧结因素对复合材料物理性能的影响进行了正交分析,得出的最佳参数为:烧结温度、烧结压力和氧化铝含量分别取900℃、600MPa和2%。
Superfine aluminum oxide powder after pretreatment was used as reinforcement. The as-pre- treated aluminum oxide powder was treated with electroless plating copper assisted by ultrasonic field. The copper matrix composites reinforced by alumina oxide were prepared by powder metallurgy. The samples were characterized by X-ray diffractometer （XRD）, scanning electron microscopy （SEM） and energy spectrum analyzer （EDS）. The results show that the aluminum oxide particles are uniformly dis- persed into copper matrix composites. In addition, the influencing factors of the sintering process on the physical properties of the composites were analyzed by the orthogonal testing. The optimized processing parameters are as follows, the sintering temperature of 900 ℃ , the sintering pressure of 600 MPa and the aluminum oxide content of 2 %, respectively.
