摘要

本研究的目的是研究镍基碳化硼(B4C)和纳米碳纤维(CNF)增强复合材料的显微组织和磨损性能。采用SEM-EDS和XRD分析了粉末冶金法制备的复合材料的微观组织和相组成。复合材料的硬度值采用维氏硬度法测定，磨损性能采用销盘法测定。扫描电镜显示，B4C分布均匀，但CNF在部分区域积聚，即使是轻微的。在基质中加入B4C和CNF可显著提高其活性。添加B4C后硬度增加较大，添加CNF后硬度略有降低。在干燥条件下进行的磨损试验结果表明，对Ni基体的强化降低了磨损率和摩擦系数。

Wear and microstructural properties of Ni-B4C/CNF composites

The aim of this study is to investigate the microstructure and wear properties of nickel (Ni) matrix boron carbide (B4C) and carbon nanofiber (CNF)-reinforced composite materials. Microstructure and phase composition of the composites manufactured by powder metallurgy (PM) method were determined by SEM-EDS and XRD analysis. While hardness values of the composites were determined by Vickers hardness measurement method, their wear properties were determined by using pin-on-disc method. SEM images showed that B4C was homogeneously distributed, but CNF accumulated in some areas, even though it was slight. Addition of B4C and CNF to the matrix significantly increased it. The increase was quite high in B4C addition, and hardness was slightly lower in the addition of CNF. According to the results of the wear test carried out under dry conditions, the reinforcement to the Ni matrix reduced the wear rate and friction coefficient.
