摘要
火花等离子体放电技术已经用于制备纯金属、合金、化合物、半导体和陶瓷材料粉末。该技术制备的粉末具有球形度好、无坩埚熔化、原位快速淬火、粉末细小等特点。介绍了火花等离子体放电制备粉末的机理、特点以及该技术制备高温合金粉末的现状。
Spark plasma discharge technique has been applied to the preparation of powder materials, like pure metals, alloys, compounds, semiconductors and ceramics. The advantages of the powders include: high sphericity, containerless melting, rapid in situ quenching, and superfine etc. The mechanism and feature of spark plasma dis- charge are presented. Development of fabrication of superalloys powder by spark plasma discharge is also discussed.
