| 摘 要： | 采用场发射扫描电镜和能谱仪对杂质含量高、硬度大的边皮海绵钛颗粒和普通海绵钛颗粒表面及内部杂质的分布进行了研究。研究发现，海绵钛中的杂质不仅具有钛坨中心部位杂质含量低周边杂质含量较高的宏观分布规律，而且具有杂质成团聚集在海绵钛颗粒表面的微观结构特征。采用化学溶解法可以显著降低海绵钛的杂质含量和布氏硬度。

| Abstract: | The distribution of impurities in the inner and the outside of titanium sponge particles was studied with field emission scanning electron microscopy（FESEM） and energy dispersive spectrometer（EDS）. The results show that not only impurities content in the central part of the whole titanium sponge is lower than that in the circular edged titanium sponge but also the impurities agglomerating on the surface of titanium sponge particles. The impurities agglomerating on the surface can be easily dissolved by dilute hydrochloric acid, which will make impurities content and Brinell hard- hess（HB） of the titanium sponge decreased obviously. |
