金属-氧化物复合粉末的制备方法

Methods Manufacturing Metal-Oxide Composite Powders

本文分析了制备CuAl2O3混合粉末的三种方法,即内氧化、共沉积和机械合金化的原理及影响因素。指出三种方法可以成功用于制备纳米级Al2O3弥散分布的CuAl2O3复合粉末,其中机械合金化法因其颗粒的可控制被推荐优先采用。

The principle manufacturing copper-alumina composite powders was analyzed in the paper. Three methods were internal-oxidation of dilute copper-aluminium alloy powders, co-precipitation of copper and aluminium ion and, mechanical alloy. It was proved that the composite powders of nano- Al2O3 particles dispersing on copper-matrix be obtained successfully with the three methods. Mechanical alloy mixing methods was a top priority to be adopted.
