1.绪言用气体对钢材表面进行渗氮是一种复杂的工艺过程,许多问题迄今仍未解决.下列实验将有助于了解氮化工艺:1.正确地确定钢气体氮化装置的尺寸;2.对钢材进行最佳预处理;3.提高装置的可重视性,同时可给出误差范围。
1. INTRODUCTION Nitriding steel surfaces with gas is a complex process and many problems remain unsolved so far. The following experiments will help to understand the nitriding process: 1. Correctly determine the dimensions of the steel gas nitriding unit; 2. The best pretreatment of steel; 3. To improve the visibility of the device, while giving the error range.
