纳米结构WC-Co复合粉末的制备与应用

Preparation and Applications of NanostructuredWCCo composite Powders

介绍了一种制备纳米结构ＷＣＣｏ复合粉末的方法———热化学合成法。该方法包括原始溶液制备、喷雾干燥生成化学均匀的前驱体粉末及其流化床热转化为纳米结构ＷＣＣｏ复合粉末。论述了制得的纳米结构ＷＣＣｏ复合粉末的结构。

This paper introduce a process of preparating nanostructured WCCo composite powders-thermochemical synthesis. The process involves preparation of starting solutions, spray drying to form chemically homogeneous precursor powders and fluid bed thermochemical conversion of the precursor powders into the nanostructured WCCo composite powders. The structures,properties and applications of prepared nanostructured WCCo composite powders are descrebed.
