钛基合金阳极表面物相的研究——X射线衍射法

Determine for Surface Phases of Ti—base Alloys Anode by X—Ray Diffraction

制备了四类Ti 基合金阳极 (Ti-Ni;Ti-C ;Ti-B ;Ti-Mn) ;用X射线衍射法确定了其表面物相的组成 ,该组成分别为 :Ti -Ni (共五相 )Ti3 Ni.TiC .TiB .Ti2 B5 及Mn .Ti-Mn2 等 。

The 4 Rinds of Ti—base alloys (TiC, TiB, TiNi, TiMn 2)have been preparation. The composition of surface phases have been determine by X—ray diffraction ,composition Ti—Ni(5 phases),Ti 3Ni,TiC,TiB,Ti 2B s,Ti—Mn,Ti—Mn 2,The cause for anti passivation of Ti—base alloys anode is discassed.
