W-Cu復合材料結合了W、Cu金屬各自優(yōu)良性能，具有良好的高溫強度、延展性、抗電弧燒結性、耐高溫氧化和低膨脹系數等特點，廣泛應用于機械加工、國防工業(yè)、航空航天、電子信息、軍事等領域。以超細納米W�睠u復合粉體為原材料是制備出性能優(yōu)越的W-Cu復合材料的主要途徑之一，受到國內外學者的廣泛關注。主要總結了W-Cu超細納米復合粉體的制備方法，如機械合金化法、化學共沉淀法、水熱合成�补策�原法、噴霧干燥法、溶膠�材�膠法、冷凍�哺稍锓ā⑷紵�法等，并通過分析現階段制備W-Cu納米復合粉體存在的問題，提出了未來該領域的研究方向。

Abstract:

W-Cu composite material combines the excellent properties of W and Cu metals, has good high temperature strength, ductility, arc sintering resistance, high temperature oxidation resistance, low expansion coefficient and other characteristics, and is widely used in machining, defense industry, aerospace, electronic information, military and other fields. Using ultrafine nano-W-Cu composite powder as raw material is one of the main ways to prepare W-Cu composite materials with superior performance, which has attracted wide attention from scholars at home and abroad. This review mainly focuses on the preparation methods of W-Cu ultrafine nanocomposite powders, such as mechanical alloying, chemical coprecipitation, hydrothermal synthesis�瞔oreduction, spray drying, sol-gel, freeze-drying, combustion method, etc, and puts forward potential research directions of this field in the future by analyzing the existing problems in the preparation of W-Cu nanocomposite powders.
