| Abstract: | The ion nitriding process with argon gas passing through hot-work die steel H13 was stated. The influence of argon atmosphere on the nitrated case and thermal fatigue behavior of steel H13 was studied by using instruments such as stereomicroscope, optical microscope, hardness meter and X-ray diffraction analyzer. The result shows that the argon gas can effectively decrease the hardness gradient and improve the thermal fatigue behavior of ion nitriding steel H13. |
