Abstract In this work, a systematic investigation was performed on the structural, mechanical and corrosion properties of CNT incorporated 304 stainless steel. Various concentrations of CNT from 0.5 to 4 wt% were incorporated into the 304 stainless steel matrix to investigate the feasibility of fabrication and enhancement of strength and other material properties. The fabrication of CNT-steel composite was achieved through a spark plasma sintering process at a sintering temperature of 800 °C. Raman and morphological studies confirmed that the CNT structure was retained in the sintered pellets. Optimum performance was found at 0.5 wt% CNT giving a Vickers hardness of 351 Hv and compressive yield strength of 404 MPa which were 5.5 and 2.0 times, respectively, those of pristine steel. Corrosion studies with 3.5 wt% NaCl solution revealed a slight increase in the corrosion rate for CNT dispersed samples.

CNT-304不锈钢纳米复合材料的结构、力学和腐蚀性能

摘要 在这项工作中，系统地研究了碳纳米管掺入 304 不锈钢的结构、力学和腐蚀性能。将 0.5 至 4 wt% 的各种浓度的 CNT 结合到 304 不锈钢基体中，以研究制造和增强强度和其他材料性能的可行性。CNT-钢复合材料的制备是通过在800°C的烧结温度下通过放电等离子体烧结工艺实现的。拉曼和形态学研究证实，CNT 结构保留在烧结颗粒中。在 0.5 wt% CNT 下发现最佳性能，维氏硬度为 351 Hv，压缩屈服强度为 404 MPa，分别是原始钢的 5.5 和 2.0 倍。3.腐蚀研究
