【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-coreduction, 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.更多还原
