铸造板是用商业钛制成的。这些平板用细小的三氧化二铁粉末的浆料抛光。用电子探针(EPMA)和X射线光电子能谱(XPS)对其表面组成和结构进行了分析。在高压抛光表面，铁的分布不均匀，但氧的分布基本均匀；而在轻压抛光的表面，铁和氧的分布很均匀，但浓度分别较低和较高。EPMA状态分析和XPS分析表明，铁在最外表面可能以Fe2+形式存在，而在内表面层可能以金属状态存在。
Cast plates were prepared from commercial titanium. The plates were polished with a slurry of fine ferric oxide powder. The surface composition and structure were investigated by electron probe microanalysis (EPMA) and X-ray photoelectron spectroscopy (XPS). In the high pressure-polished surface, iron was non-uniformly distributed but oxygen was mostly uniformly distributed, while in a light pressure-polished surface, iron and oxygen were uniformly distributed though at lower and higher concentrations, respectively. EPMA state analysis and XPS suggested that the iron might exist as Fe2+ in the outermost surface, while it might be in a metallic state in the inner surface layer.
