| 摘 要： | 采用低温气体多元共渗技术在20钢表面同时渗入碳、氮、氧三种元素,利用X射线衍射仪(XRD)测定了渗层的相组成;另外测试了渗层在浓度为1.0 mol/L HCl溶液中的耐蚀性.结果表明:渗层以氧化物、氮化物和碳化物为主,且氮化物居多,其腐蚀速率明显低于基体材料的腐蚀速率.

| Abstract: | Corrosion performance of 20 steel was improved by low temperature gas multi-element penetration technique. Carbon, nitrogen and oxygen were infiltrated into the material. The phase constituents of the alloying layer were investigated by XRD. The corrosion resistance of the penetrated layer and original material was compared by electrochemical method in 1.0 mol/L HC1 solution. The results show that the penetrated layer consists of oxide, nitride and carbide. Among them the nitride is predominant. In comparison with the original material, the penetrated layer has much better corrosion resistance and lower corrosion rat . |
