Surface chemistry of the titanium powder has particularly growing interest due to the increasing application of titanium components prepared by powder metallurgy, in particular metal injection moulding and additive manufacturing. Due to the high chemical activity, number of titanium oxides, calcium and complex Ca–Ti–oxides can be expected on the component/medical implant surface, depending on powder and component manufacturing and post-treatment, but are very difficult to analyse due to the lack of the experimental data and analysis methodology. Therefore, a methodology for the analysis of the surface chemistry of the Ti-powder by XPS utilising internal standard reference was developed. The obtained methodology was used for the surface analysis of titanium powder and identification of its surface oxide composition. The results show that the powder surface is covered by TiO2 layer in the form of rutile with a thickness of 4.4?nm. Carbon and nitrogen impurities were also found present on the powder surface. 相似文献

采用SEM、EDS和大样电解法研究了某种镀锌板表面胞状凸起缺陷的形成原因。结果表明:冷轧板表面起皮缺陷是造成镀锌板表面胞状凸起缺陷的直接原因。冷轧原料板近表层分布着尺寸大于300 μm的长条状硅酸盐夹杂带,且夹杂带中分布着块状氧化铁夹杂。与缺陷镀锌板同批次酸洗板机械研磨去掉近表层,随后冷轧试验表明,块状氧化铁夹杂不是造成镀锌板表面胞状凸起缺陷的主要原因。缺陷镀锌板铸坯中夹杂物含量为100.32 mg/10 kg,夹杂物主要由尺寸大于140 μm大型夹杂物组成,而正常镀锌板铸坯中夹杂物含量为20.98 mg/10 kg,证实钢中大型硅酸盐类夹杂是导致镀锌板表面凸起缺陷的根本原因。 相似文献
