摘要
采用非平衡磁控溅射的方法,构建了Fe-C-Si非晶合金体系,详细探讨了Si对该非晶合金体系结构与性能的影响,研究结果表明:Si元素在溅射过程中促进合金非晶化;在退火状态下,Si元素通过碳的有效排出、铁的结晶性升高以及促进Fe3C石墨化等作用机理,整体降低体系的热稳定性;同时,Si元素的引入,使薄膜导电能力增强,硬度提高,但耐蚀性能下降。本研究工作将为新材料的设计和开发提供参照和启发。
The Fe-C-Si amorphous alloy system was constructed by unbalanced magnetron sputtering and then the effect of Si on the microstructures and properties of the disordered alloy system was discussed in detail.The study results showed that the element of Si promoted amorphization of the disordered alloy during the sputtering process.Furthermore,during the annealing process,the presence of Si reduces the overall thermal stability of the system by application of such mechanisms of action as carrying out efficient emissions of carbon,improving the crystallinity of Fe substrate and promoting graphitization of Fe3C.Simultaneously,the introduction of Si enhanced the film's conductivity and increasing of hardness,but the corrosion resistance decreased.So these studies on this project would offer valuable references for designing and developing new materials.
