Effects of Different Surfactants (PEG/CTAB and Their Combinations) on Corrosion Resistance of Ni‐P‐Si <sub>3</sub> N <sub>4</sub> Composite Coatings
ABSTRACT In this paper, the effects of surfactants such as PEG, CTAB and their combination (PEG: CTAB) on the microstructure and corrosion resistance of Ni‐P‐Si 3 N 4 composite coating were systematically studied. The electrochemical test shows that adding PEG or CTAB can reduce the coating defects and improve the corrosion resistance. When PEG and CTAB are used in combination, they show synergistic effect, which further enhances the compactness and corrosion protection of the coating. Among them, when the composite ratio is 3:1 (CTAB: PEG), the corrosion current density is significantly reduced, and the stability of the coating in corrosive medium is improved.
