This work studied the effect of self-protective paste nitriding (SPN) and ion plasma (IPN) on surface chemistry, microstructure, nanohardness AISI 304 316L stainless steels, with both treated at 440 °C for 5 h. Surface modifications analyzed using SEM nanoindentation revealed distinct outcomes. SPN induced an oxynitriding due to oxidation properties pastes, forming Fe3O4 FexC phases, while IPN produced expanded austenite layer. Both methods enhanced nanohardness, but showed superior results. For SS, increased by 367.81% (6.83 GPa) compared a 133.5% increase (3.41 IPN. improved 26% (2.23 GPa), whereas reduced it 48% (0.92 GPa). These findings highlight SPN’s potential as effective anti-wear treatment, particularly SS. The process utilized eutectic mixture sodium cyanate carbonate, employed N2:H2 (1:1) gas mixture. analyses confirmed formation γ-Fe(N) indicating dispersed iron nitrides (FeN, Fe3N, Fe4N). simultaneous nitrocarburization led oxide layer above nitride diffusion layer, enhancing mechanical through oxides (Fe3O4) carbides (FexC). Comparative analysis that exhibited better performance than 304, underscoring effectiveness modification.
