โฆ Synopsis
The sol-gel technique to deposit coatings on metals by dipping was studied. Different metals (Cu, Ni, Fe, Al) were coated with grO 2, SiO 2, TiO 2 and B203-3i02 solutions. The influence of some dipping and solution parameters was related with the quality of the obtained coatings. A scale of quality was determined to elass(ยฃv the sol-gel coatings on metals. Both fresh and aged solutions, as-received and abraded substrates were used. The protection against oxidation was evaluated by XRD and by measuring the weight gain upon thermal treatment.

The sol-gel dipping process, in which liquid silicon alkoxide is transformed into the solid silicon-oxygen network, can produce a thin film coating of silica (SiO 2 ). The features of this method are high homogeneity and purity of the thin SiO 2 film and a low sinter temperature, which are important
