摘要
在电子束选区熔化金属粉末技术中,为了避免电子束对金属粉末的作用力破坏金属粉末的堆积状态,建立了金属粉末受力模型,并对其进行受力分析和计算。理论分析和实验证明:当球形和非球形粉末以3:2的比例混合时,可以得到很好的成型效果。
In order to avoid disruption of the metal powder during electron beam selective melting technology, a model of characteristios of metal powder and EBSM parameters has been established in this study. Experimental and theoretical analysis of the powder deposition process showed that production＇s quality is lie on diameter and frictional modulus, primarily. And there is a satisfying production when proportion is 4 to 1 of spherical and non spherical powder mixed.
