本文中应用扫描电镜(SEM)、俄歇电子能谱仪(AES)和微区X-光衍射仪分析研究了陶瓷等离子喷涂层(Cr_3C_2、Al_2O_3+13％TiO_2)表面在450℃高温下与润滑油中添加剂元素Ca、S和P等在摩擦过程中形成的化学表面膜。用SEM观察表面形貌,AES分析表面膜元素随深度的变化,以及微区X-光衍射仪鉴别表面膜的晶体结构。结果表明,微区X-光衍射是研究表面膜结构的有效方法,化学稳定性良好的陶瓷表面在高温摩擦下能与添加剂中活泼元素Ca、S、P等反应生成化学表面膜,从而降低了陶瓷间的摩擦与磨损。
In this paper, the surface of ceramic plasma sprayed coatings (Cr 3 C 2, Al 2 O 3 + 13% TiO 2) was studied by scanning electron microscopy (SEM), Auger electron spectroscopy (AES) and micro- Oil in the additive elements Ca, S and P in the friction process of chemical surface film. The surface morphology was observed by SEM. The elemental depth of the surface film was analyzed by AES, and the crystal structure of the surface film was identified by X-ray diffraction. The results show that the micro-area X-ray diffraction is an effective method to study the surface membrane structure. The chemical stability of the ceramic surface can be chemically reacted with the active elements Ca, S, P in the additive under high temperature friction to reduce the chemical surface film Friction and wear between ceramics.
