Abstract

Using an immersion method, an organic methyltrimethoxysilane (MTMS) coating was prepared on the surface of aluminum alloys at room temperature. A more corrosion-resistant coating has been successfully developed by optimizing hydrolysis conditions, adding surfactant OP-10 and conducting maturation treatment. To characterize the solution, a conductivity meter, transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), and a particle size analyzer were utilized. As for the analysis of the surface properties of the samples, a series of methods such as X-ray photoelectron spectroscopy (XPS), attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR), contact angle measurements, scanning electron microscopy (SEM), electrochemical impedance spectroscopy (EIS), and Tafel polarization analysis were adopted. The results showed that the synergistic effect of OP-10 and maturation treatment can significantly improve the corrosion resistance of the coating.
