INFLUENCE OF ALLOYING ELLEMENTS ON THE THICKNESS OF THE NITRIDED LAYER IN MULTILAYER STEEL MATERIALS
It was found that mainly diffusion occurs along the grain boundary, and a diffusion profile is formed in the AISI409 and AISI304 layers, there is no diffusion profile in the 1008 steel layers, which may be due to the low solubility of nitrogen in iron. It was also found that the depth of the nitrided layer in steel AISI304 is less than that in the steel layer AISI409, due to the nickel content, which has an inhibiting effect on diffusion processes.
