雾化工艺对弥散铜粉末制备及成形的影响
Influence of atomization process on the preparation and forming of dispersed copper powder
摘要
Abstract
To gain a deeper understanding of the influence of atomization processes on the properties and formability of Al2O3-dispersed copper powders,two atomization methods nitrogen atomization and water atomization were employed to prepare Al2O3-dispersed copper powders.This study investigated the effects of atomization pressure on the particle size composition,oxidation degree,and apparent density of the powders produced by both methods.Additionally,the cold isostatic pressing(CIP)formability of the nitrogen-atomized and water-atomized Al2O3-dispersed copper powders was explored.The results indicated that,under an atomization pressure of 10 MPa,the powder yield of-100-mesh water-atomized dispersed copper powders was approximately 30%higher than that of nitrogen-atomized powders.Water-atomized powders contained a significantly higher content of Al2O3,with the Al2O3 content exceeding twice that of nitrogen-atomized powders at the same particle size.Moreover,the tap density of water-atomized powders was lower,reaching around 70%of that of nitrogen-atomized powders.Under the same particle size and loose packing conditions,the CIP formability of nitrogen-atomized dispersed copper powders was inferior to that of water-atomized powders.关键词
