这项研究调查了磨损钛表面的污染情况。使用抛光机，在水冷却下用防水碳化硅砂纸打磨样品。使用元素分析、X 射线衍射和硬度测试来检查磨损表面。在整个表面上观察到尺寸达到约30微米的污染物沉积物。在这些沉积物中，Ti明显减少了约10％并被Si和O取代。Si的化学键状态类似于SiC或硅化钛。 O固溶在Ti中，提高了表面硬度。污染物沉积物是无定形的或非常薄。 Ti 的污染程度与硬度有关，是由与磨料的反应造成的。
This study investigated the contamination of abraded Ti surfaces. Using a polishing machine, specimens were abraded with waterproof SiC grit papers under water cooling. The abraded surfaces were examined using element analysis, X-ray diffraction, and hardness tests. Contaminant deposits with dimensions reaching about 30 microns were observed throughout the surface. In these deposits, Ti was apparently reduced by about 10% and replaced by Si and O. The chemical bond state of the Si was similar to that of SiC or a titanium silicide. The O was solute in Ti, which increased the surface hardness. The contaminant deposits were amorphous or very thin. The contamination of Ti, the extent of which was related to hardness, resulted from a reaction with abrasives.
