摘要

为了改善铜-陶瓷颗粒界面的浸润性

提高铜与陶瓷颗粒的结合强度

用高速气流将陶瓷颗粒吹入熔融铜液中制备成弥散铜系列复合材料。结果证明

颗粒表面处理提高了复合材料的界面结合强度

并且使用复合弥散相

使复合材料在硬度、屈服强度、导电性能等方面均有不同程度的提高。

Abstract

Disperoids Cu matrix composites have been prepared by blowing ceramic particle into liquid Cu with high-speed gas-flow to investigate the effects of particle surface treatment on wettability of Cu-ceramic particle interface and bonding strength between Cu and ceramic particle. The results reveal that surface treatment of ceramic particle can obviously improve interfacial bonding strength of the composites. Furthermore

hardness

yield strength and electric conductivity of the composites can be improved to a certain by adding compound dispersively ceramic particle （treated MgO particle and treated CeO

particle）.
