摘要：
Sol-Gel process is an original method for processing semi-organic thin films on steel sheets. Silicone coatings containing methyl and phenyl groups produced by hydrolysis and condensation of alkoxysilanes present high thermal resistance and chemical stability. Meanwhile, adhesion properties are marginal when compared to other kinds of semi-organic coatings used on ferrous substrates. The addition of an appropriate organic polymer increases flexibility and adhesion of the coating and enhances its use on steel sheets. Adhesion improvement mechanism has been studied by specular and diffuse reflectance FTIR spectroscopy.
