| 摘 要： | 采用液相等离子体电解渗方法,在80%甘油水溶液中实现了304不锈钢表面快速渗碳。研究施加电压和放电时间对渗碳过程的影响,分析了渗碳层的显微组织,并比较了不同工艺条件下渗碳层显微硬度分布。结果表明:经过5 min的快速放电处理,渗碳层厚度接近100μm,硬度达到880 HV。在350 V和3 min渗透条件下渗碳层质量较好。

| Abstract: | Rapid carburization on 304 stainless steel was achieved by plasma electrolytic carburizing in 80% glycerin aqueous solution.The influence of applied voltage and discharge duration on carburizing process were investigated,and the microstructure and microhardness profiles of carburized layers under different condition were analyzed.The results show that after rapid discharge for 5 min,the depth of carburized layer is close to 100 μm and its microhardness is up to 880 HV.It is found that the carburized layer obtained under 350 V and 3 min conditions has higher performance. |
