摘　　要：金属粉末作为MIM技术的关键原料,其品质很大程度上决定了产品的最终质量。水气联合雾化制粉具有椭圆微观形貌、比表面积大等优异的理化性能,成为MIM制造高性能制品的主要原材料之一。但羰基法、气雾化法、气流磨粉碎法和等离子体雾化法制粉技术所制备的粉末各有其优势,也是MIM制品广泛应用的原材料。本文综述了MIM用金属粉末的主要几种制备技术原理,总结其存在问题,并对MIM用金属粉末制备技术提出新的展望。As the key raw material of MIM technology,the quality of metal powder largely determines the final quality of products.Water air combined atomization powder production has excellent physical and chemical properties such as elliptical microstructure and large specific surface area,and has become one of the main raw materials for MIM manufacturing high-performance products.However,the powders prepared by carbonyl method'gas atomization method,airflow grinding method and plasma atomization method have their own advantages and are also widely used as raw materials for MIM products.In this paper,the main preparation technology principles of metal powder for MIM are reviewed,and the existing problems are summarized,and the new development direction of metal powder preparation technology for MIM is put forward.
