“…The oxide ceramics arouse especial interest because of their advantages such as chemical and thermal resistance and barrier properties [1][2][3]. In order to develop the best protective and mechanical properties not only unary but also composite ceramic coatings have been investigated [4][5][6]. There are a number of methods for deposition of protective ceramic coatings such as physical vapor deposition (PVD), chemical vapor deposition (CVD), plasma spraying, and sol-gel method.…”

In this work, we compare the protective properties, morphology, and adhesion of unary and composite, sandwich Al 2 O 3 -TiO 2 coatings deposited on X5CrNi18-9 austenitic stainless steel using the sol-gel method. It is found that the type and sequence of the films in investigated composite sandwich coatings have essential influence on their properties. The best protective properties exhibit coatings in which Al 2 O 3 film is directly on the substrate surface. The best adhesion is revealed in coatings in which TiO 2 film is directly on the steel surface. It is found that composite oxide sol-gel coatings improve the resistance of stainless steel better then unary coatings both in the range of electrochemical and high-temperature corrosion. This improvement can result from mutual influence of titania and alumina films by delay of their crystallization process.

“…A convenient way for corrosion protection is the sol-gel deposition of thin protective coatings that act as a barrier to separate the sensitive metal from the aggressive environment [6][7][8][9][10]. The major advantages of the sol-gel approach are the low process temperatures, the hardness and density of the coating material and most of all its resistance against corrosive attacks.…”

“…But alumina shows non-wettable behavior and thermal expansion coefficients mismatch with carbon steel. To improve the adherence of the coating by sol-gel technology to its substrate, various pretreatments have been adopted, such as sand-blasting, phosphate treatment, chromating, hot dipping, combined laser/sol-gel processing and alloy intermediate precoating [8][9][10]. However, the modes of bonding are mainly mechanical and the bonding strength of films with steels is only several MPa.…”
