This research is aimed at developing a better understanding of ion beam-assisted deposition to produce useful coatings on metal alloys. Of particular interest are the effects of several process variables on the mechanical behavior of the coated materials. Film morphology, composition, and geometry are controlled to optimize film properties. Emphasis is on improved fracture toughness while maintaining oxidation resistance by creating alternating oxide (alumina) and metal (aluminum) layers. Mechanical properties are determined by the ultra-low load indentation method, tensile testing, four-point bending, and indentation-fracture techniques. The structure of the microlaminates is correlated with the processing parameters and mechanical properties.

这项研究旨在更好地理解离子束辅助沉积，以在金属合金上产生有用的涂层。 特别令人感兴趣的是几个工艺变量对涂层材料机械行为的影响。 控制薄膜形态、成分和几何形状以优化薄膜性能。 重点是通过形成交替的氧化物（氧化铝）和金属（铝）层来提高断裂韧性，同时保持抗氧化性。 机械性能通过超低负载压痕法、拉伸试验、四点弯曲和压痕断裂技术测定。 微层压板的结构与加工参数和机械性能相关。
