若将微量的氧添加到 NH_3中,在短时间内就可实现氨气氮化处理,获得和软氮化处理相同或者更好的性能。这个事实被确认以来,使用工业规模的箱式周期式炉,将氧氮化处理应用到各种汽车零件、模具,并进行装车及实机耐久试验,证明获得了良好的实用性及降低成本的效果。一、在热锻模的应用热锻模,现在一般采用氨气体氮化,520℃×50h 长时间处理。从节能观点出发,研究了各种各样的缩短时间的处理方法。为
If a small amount of oxygen is added to NH 3, ammonia nitriding can be achieved in a short period of time, achieving the same or better properties as nitrocarburizing. This fact has been confirmed, the use of industrial-scale box-type periodic furnace, the oxy-nitriding applied to a variety of automotive parts, molds, loading and real machine durability test proved to have achieved good practicality and reduce costs Effect. First, the application of hot forging die Hot Forging Die, now commonly used ammonia gas nitriding, 520 ℃ × 50h long treatment. From the viewpoint of energy conservation, various methods of reducing the time are studied. for
