Ultrafine W-Cu Composite Powder Research Progress

摘要

With the increased market demand of W-Cu composite materials, the research of ultrafine W-Cu composite powder is gradually in-depth, and some achievements have been made. This article describes some ultrafine W-Cu composite powder preparation methods in recent years, such as the mechanical alloying, oxide co-reduction, mechanical thermal chemical method, homogeneous precipitation method, spray drying, sol-gel method, etc. We simply analyzed the advantages and disadvantages of each method.
