Abstract

We investigated the effects of the flame-ablation treatment on the inner surface of borosilicate glass vials and the adhesion of fluorinated diamond-like carbon coating to glass vials. Transmission electron microscopy with energy-dispersive X-ray spectroscopy analysis show that the flame-ablation treatment removed the less durable layers that contained sodium borate, which might cause elution and delamination in an aqueous solution, and formed a flat surface. The outermost surface of the flame-ablated inner wall of the vials formed a microcrystal layer containing Na and K. In addition, the flame-ablation treatment improved the adhesion of the coating to the glass vials. The EDX maps show that F derived from the F-DLC coating and Na and K derived from the glass were mixed and formed an interface layer between the F-DLC coating and the glass vial. This result indicates that the flame-ablation treatment is a promising method to improve the adhesion of the coating to borosilicate glass vials.

硼硅玻璃小瓶火焰烧蚀表面的分析 TEM 观察

摘要

我们研究了火焰烧蚀处理对硼硅玻璃小瓶内表面的影响以及氟化类金刚石碳涂层对玻璃小瓶的附着力。具有能量色散 X 射线光谱分析的透射电子显微镜显示，火焰烧蚀处理去除了含有硼酸钠的不太耐用的层，这可能会导致水溶液中的洗脱和分层，并形成平坦的表面。小瓶火焰烧蚀内壁的最外表面形成了含有钠和钾的微晶层。此外，火焰烧蚀处理提高了涂层对玻璃小瓶的附着力。EDX 图显示，来自 F-DLC 涂层的 F 和来自玻璃的 Na 和 K 混合并在 F-DLC 涂层和玻璃小瓶之间形成界面层。
