摘　　要：本文采用化学分析、电子扫描、激光粒度分析、水淘洗等方法,研究了氮气雾化高速钢2060粉末化学成分、形貌、粒度、夹杂物、物理性能等特征。结果显示:粉末气体含量低,呈球形,表面相对光滑且主要为胞晶组织。粉末中夹杂物含量较少,成分富含镁、铝。粉末粒径细,呈对数正态分布,并且具有较高的松装密度和振实密度。粉末填充性和均匀性较好,有利包套和热等静压。In this paper,the chemical composition,microstructure,particle size,inclusions and physical properties of nitrogen atomized 2060 high speed steel powder was studied by means of chemical analysis,electronic scanning,laser diffraction measurement,water elutriation,etc.It was revealed that the particles were spherical in shape with low gas contents and relatively smooth surface of cell structure.The main inclusions were rich in Mg and Al.The powder was fine and in a logarithmic normal distribution with a high apparent density and tap density.Consequently,the excellent filling properties and uniformity help powder canning and hot isostatic pressing.
