NSF Young Investigator

在NYI奖下，将重点研究薄膜的摩擦学行为，重点是工艺、衬底表面形貌和相关涂层/衬底性能的影响。通过改变基材的表面形貌和严格控制涂层厚度来提高涂层附着力的可能性将被评估。最初的重点将是在不锈钢和碳钢衬底上沉积类金刚石和立方氮化硼薄膜。在以后的阶段，将尝试通过将硬涂层材料与较软的固体润滑剂材料共沉积来开发低摩擦薄膜。

Under an NYI award the tribological behavior of thin films will be studied with emphasis on the effects of processing, topography of the substrate surface, and relative coating/substrate properties. The possibility of enhancing coating adhesion by engineering the surface topography of the substrate and by closely controlling the coating thickness will be evaluated. Initial emphasis will be on the diamond-like and cubic boron nitride films deposited on stainless steel and carbon steel substrates. At a later stage, attempts will be made to develop low friction films by co- deposition of a hard coating material with a softer solid lubricant material.
