| 摘要: |
| 低温盐浴渗碳、等离子渗碳等低温渗碳工艺在提高奥氏体不锈钢表面强度的同时，会降低其耐蚀性能。为克服上述缺陷，开发了一种高效兼顾表面强度与耐蚀性能的表面强化工艺的低温气体渗碳技术。采用该工艺对304、316奥氏体不锈钢进行渗碳处理，并对得到的奥氏体不锈钢低温渗碳组织性能进行分析。结果表明，随着温度升高，试样表面强度提高，而腐蚀性能下降。470℃是兼顾强化与耐蚀性能的低温气体渗碳工艺参数。 |

| Abstract: |
| Low temperature carburizing process, such as salt bath carburizing and plasma carburizing can improve the surface strength of the austenite stainless steel, but reduce the corrosion resistant performance. A gas carburizing technology at low temperature was developed, which can both improve the surface strength and corrosion resistant performance. 304 and 316 austenitic stainless steel were carburized by low temperature carburizing process, and the hardness and performance was analized. The results show that the surface strength enhances, however, the corrosion resistance reduces with the temperature increase. The austenitic stainless steel shows good strength and corrosion resistance under the condition of 470 ℃. |
