Effect of [Tris(trimethylsiloxy)silyethyl]dimethylchlorosilane on the corrosion protection enhancement of hydrophobic film coated on AISI 304

The effects of Organofunctional moieties and the adhesion properties of hydrophobic [Tris(trimethylsiloxy)silyethyl]dimethylchlorosilane (Alkyl)] coated on AISI 304 to determine the corrosion resistance were investigated and presented. Two different types of adhesion, namely: silicon oxide and plasma silicon oxide films were grown on AISI 304 with the aid of an atomic-layer deposition technique. The effects of the surface preparations on the functionality and the properties of the hydrophobic silane coating were characterized, using the scanning electron microscope (SEM) and the atomic force microscope (AFM) for morphology and topography. X-ray diffraction (XRD) and attenuated Fourier-transform infrared (FTIR-ATR) were used for the chemical composition and the bonding structure, the water contact angle were measured and processed, as well as the determination of electrochemistry of the coated and uncoated surfaces. The results showed that the silicon oxide treated surface improved the durability of the silane film in the corrosive medium; and that has more chemical stability with the coating, when compared with the plasma silicon oxide and base material, which was distinctly discussed.
