| 摘 要： | 采用以尿素为主要原料的液体软氨化工艺，对阀杆（３５钢）进行了氮化处理。并通过不同配方、不同温度及时间，对渗层疏松及渗层深度作了对比试验。试验结果表明，渗层疏松主要是由于盐浴内ＣＮＯ－浓度过高所致；而渗层深度则随氮化温度、氮化时间及其盐浴成分配方的不同而变化。

| 关 键 词： | 液体软氮化，渗层疏松，渗层深度 |

| Abstract: | The valve rod (steel 35)is nitrided in the fluid soft nitriding process,the main material being made up of urea.The comparative test of porosity and depth of nitrided layer has been made by using different prescripitions, at different temperature and time. The result shows that the porosity of nitrided layer is due to the over concentration of CNO- in the salt bath. The nitrided depth changes with the differences of temparature, time nitriding and composition of the salt bath. |

| Keywords: | fluid soft nitriding porosity of nitrided layer nitrided depth |
