Web28 sep. 2012 · The 8N samples formed highest thickness of nitrided layer with 12.84 μm, followed by 5N with 7.93 μm and 2N with 1.34 μm. Fig. 3(a) showed that nitrided layer formed on 8N samples was not uniform. However, for 2N and 5N samples in Fig. 3(b-c), the layers are uniform.The characteristic of gas nitriding technique more likely to occur with … WebAlthough the produced nitrided layer has the required thickness and hardness, its compound zone has a tendency to be too thick and must be mechanically removed after processing after gas method. Also, masking/protecting from nitriding in gas nitriding is more complicated than in ion nitriding.
