Abstract
Various methods and systems are provided for providing coatings and textures to surfaces of a bearing assembly in an x-ray system to control the wettability of the surfaces when components of the bearing assembly rotate during operation of the x-ray system. A lubricant is disposed in a gap formed between a shaft and a sleeve of the bearing assembly such that textured and coated surfaces of the shaft and sleeve alter wetting properties between the lubricant and surfaces. The coatings and textures can be wetting or anti-wetting to further enhance control over the behavior of the lubricant.
