Abstract

A technology of metal modification with carbon nanotubes (CNTs) is developed using electric arc surfacing. It involves the use of extruded metal rods containing CNTs as a deposited material. This technology is used to modify an AMg5 alloy. A comparison of the macro- and microstructures of the metal modified by the developed technology by adding CNTs and the corresponding unmodified metal does not reveal a significant difference. However, CNTs are detected in the modified metal using scanning electron microscopy, and microhardness analysis shows that the addition of CNTs increases the microhardness of the upper layers of the deposited metal.

碳纳米管在改变铝镁合金微观组织和力学性能中的应用

摘要

使用电弧堆焊开发了一种用碳纳米管(CNT)进行金属改性的技术。它涉及使用包含CNT的挤压金属棒作为沉积材料。该技术用于修饰AMg5合金。通过添加碳纳米管和相应的未改性金属对通过发达技术改性的金属的宏观和微观结构进行比较,没有发现显着差异。然而,使用扫描电子显微镜在改性金属中检测到CNT,并且显微硬度分析表明,CNT的添加增加了沉积金属的上层的显微硬度。
