| 中文摘要: |
| 采用常规离子渗氮、循环离子渗氮、循环N/C/O 共渗及循环N/C/O/S共渗四种不同工艺分别对316Ti不锈钢铆钉进行处理,并对试样进行表征,分析了循环渗氮工艺及共渗元素C,O 和S对316Ti钢渗层组织及耐腐蚀性的影响。结果表明:与常规离子渗氮相比,循环渗氮的试样渗层更深,耐腐蚀性基本不变;N/C/O 共渗中,C和O 元素的加入有利于提高渗层深度并抑制CrN 的析出,降低基体表面贫Cr程度,提高处理后试样的耐腐蚀性;共渗介质中加入S元素,会降低共渗试样的耐腐蚀性。 |
| 英文摘要: |
| The 316Ti stainless steel rivets were treated respectively by four different technologies of conventional ion nitriding, cyclic ion nitriding and cyclic N/C/O penetration and cyclic N/C/O/S penetration. The samples were characterized. The influence of cyclic nitriding technologies and C,O,S penetration elements on the 316Ti steel layer structure and corrosion resistance were analyzed. The result shows that the diffusion layers of the samples cyclic nitrided are deeper and the corrosion resistance hardly be changed, compared with conventional ion nitriding; In N/C/O penetration, adding the elements of C,O were benefit for enhancing layer depth and restraining CrN precipitation, as well as decreasing the poor Cr degree of matrix surface, and improving corrosion resistance of the sample processed, S can decrease corrosion resistance of the sample processed by penetration. |
