采用合适的粉末配比方案,配备不同成分的粉末材料,研究了粉末颗粒中各种成分对生胚密度的影响。结果表明,通过设计在基体材料中填入颗粒尺寸更小的微细粉或者合金元素以及纳米粉末等,可以达到粉末颗粒空隙的最佳填充效果。使粉末颗粒之间紧密堆积,从而提高了粉末件密度。 Using appropriate powder proportioning scheme, with different ingredients of the powder material, the study of the various components of the powder particles on the density of the embryo. The results show that the best filling effect for the void of powder particles can be achieved by designing the base material to be filled with the fine particles with the smaller particle size, alloying elements and nano-powders. The powder particles are closely packed, thereby increasing the powder density.
