A simple and novel approach for the in situ formation of Carbon-based films is developed in this study. Experimental results reveals that the tribofilm significantly reduced the friction coefficient by nearly 80%, compared to the substrate. The film thickness, determined to be approximately 200   nm via the Dichromatic Interference Intensity Modulation (DIIM), Atomic Force Microscopy (AFM), and Transmission Electron Microscopy (TEM), is confirmed with high precision. This friction reduction is attributed to the diamond-like structural and chemical characteristics of the formed film. The tribofilm formation is driven by the synergistic interaction of three mechanisms: the entrainment of nanoparticles by the lubricant, the chemical adsorption of nano-additives, and the catalytic activity of magnesium ions (Mg 2+). Numerical calculations further confirm the universality of the growth conditions, indicating that this method holds potential for surface strengthening applications in mechanical components.
