| 摘 要： | 基于组合材料芯片技术原理,通过离子束溅射方法,在低碳钢基片上快速制备了全组份范围的二元Zn-Al薄膜材料样品库,研究了不同热处理条件对薄膜组份互扩散过程的影响.使用XRD及EDS等手段表征薄膜的成分和结构,并采用原子力显微镜和透射电了显微镜观察形貌;使用纳米压痕仪测试材料芯片样品的压痕硬度和弹性模量;使用电化学方法测试平衡电位和极化电阻.在获得薄膜材料样品组成-结构-性能(力学性能和耐腐蚀性能)关联特性的基础上,对具有良好力学性能和耐腐蚀性能的二元Zn-A1合金镀层材料提出了成分设计和优化方案,即选择兼具良好力学性能和耐蚀性能的Al-Zn镀层材料,成分配比应控制为约30at%Zn含量. |

| Abstract: | A combinatorial method was used to deposit a Zn-Al material library on a low car- bon steel substrate by ion beam sputtering.As-deposited film samples were annealed at varied heat treatment conditions to promote the diffusion between the elements for a through-thickness homogenous sample.XRD and EDS analyses were carried out for composition and structure,AFM and TEM images were obtained for morphology observation.Nanoindentation tests were conducted to investigate the mechanical behaviour of samples.Electro... |
