Abstract

Zr-Cu based thin-film metallic glass (TFMG) has good glass-forming ability and the addition of a third element can create a chaotic system capable of inhibiting the nucleation and growth of crystals. This study focused on TFMGs made with Zr, Cu, and Ti in various compositions deposited via high-impulse magnetron sputtering on silicon and 304 stainless-steel substrates. Detailed analysis was performed on the microstructure and surface characteristics of the resulting coatings. Transmission electron microscopy revealed that the multilayer structure changed to a nanocrystalline structure similar to an amorphous coating. The excellent hydrophobicity of Zr-Cu-Ti TFMGs can be attributed to their ultra-smooth surface without any grain boundaries. The excellent antimicrobial effects can be attributed to a hydrophobic surface resisting cell adhesion and the presence of copper ions, which are lethal to microbes.

摘要

锆铜基薄膜金属玻璃（TFMG）具有良好的玻璃形成能力，添加第三种元素可以创建一个能够抑制晶体成核和生长的混沌系统。本研究聚焦于通过高脉冲磁控溅射在硅和304不锈钢基板上沉积的各种成分的锆、铜和钛制成的TFMG。对所得涂层的微观结构和表面特性进行了详细分析。透射电子显微镜显示，多层结构转变为类似于非晶涂层的纳米晶体结构。Zr-Cu-Ti TFMG的优异疏水性可归因于其无任何晶界的超光滑表面。优异的抗菌效果可归因于疏水表面抵抗细胞粘附以及对微生物具有致命性的铜离子的存在。
