Enhancing Corrosion Resistance of AISI 1045 Steels Using Melamine Based NitridingPages 355-360
Elias Tadesse Fisha Abstract:
Nitriding of AISI 1045 steel using melamine derived from urea significantly enhances its corrosion resistance characteristics. The nitriding process forms a compound layer on the steel surface with a thickness ranging from 5 μm to 20 μm, which contributes to the material's improved performance. Cyclic voltammetry and microscopic analysis demonstrate that the melamine-nitrided AISI 1045 steel exhibits superior corrosion resistance property than the untreated steels. The layer acts as a barrier, reducing the steels’ susceptibility to corrosive media. The results indicate that melamine-based nitriding not only improves corrosion resistance but also enhances the mechanical properties of the steel, such as wear and friction resistance. Nitriding of AISI 1045 using melamine derived from urea, offering a promising approach for surface modification in industrial applications where durability and wear resistance are critical. The study highlights the potential of using urea-derived melamine as an effective nitriding agent for improving the surface integrity of AISI 1045 steel, thereby extending its operational lifespan in aggressive environments.
