目前离子氮化存在三个问题。1.如何在低氮浓度下进行氮化;2.氮化时的正确测温;3.碳氮共渗处理技术。对SUS304与420钢在各种条件下进行离子氮化,然后进行耐蚀性与导磁性试验,结果发现不锈钢在离子氮化之后,表面层虽明显硬化,但却失掉了原来的耐蚀性与非磁性。在非氧化性酸性溶液中进行耐蚀试验,与未经处理的材料相比,离子氮化后的耐蚀性要差得多,而且这一倾向是随氮的渗入量增加而下降得越显著。导磁率亦是如此。为此,氮
There are three problems with ion nitriding. 1. How to carry out nitriding under low nitrogen concentration; 2. Correct temperature measurement during nitriding; 3. Carbonitriding treatment technology. The SUS304 and 420 steel under various conditions of ion nitriding, and then corrosion resistance and permeability test showed that stainless steel after ion nitriding, although the surface layer significantly hardened, but lost the original corrosion resistance and Non-magnetic. Corrosion resistance tests in non-oxidizing acidic solutions showed much worse corrosion resistance after ion nitriding compared to untreated materials, and this trend was more pronounced with decreasing nitrogen infiltration . Magnetic permeability is also true. To this end, nitrogen
