表層氮化的方法与原理表層硬化的方法很多,氮化法是其中的一種。操作的方法是把工作物放在氮化箱(Nitriding box)里,加熱到850°F至1200°F的溫度範圍,使其表面與氮氣接觸約一二日,使工作物表层高度硬化。氮化完成后就在炉內冷却到400°F,再取出在空氣里冷却到室温。氮化硬化法的詳細原理,现在還不完全知道。普通的解释如下:當氨氣在相當高的温度时就分解为氮与氢, Surface nitridation methods and principles There are many ways of surface hardening, nitriding is one of them. This is done by placing the workpieces in a Nitriding box and heating them to a temperature in the range of 850 ° F to 1200 ° F. The surface is exposed to nitrogen for about a day or two to harden the work surface. After the nitriding is completed, it is cooled to 400 ° F in the furnace and taken out to cool to room temperature in the air. The details of the nitriding method are not yet fully understood. Common explanation is as follows: When ammonia gas at a fairly high temperature decomposition of nitrogen and hydrogen,
