The influence of heat treatment of inorganic conversion coatings produced by sol-gel dip coating on the anticorrosive properties of alumina films deposited on steel substrate - Part II: silica/boehmite or boehmite/silica multilayered conversion coatings

Following on the results presented in the first part of this study, the focus of attention now shifts to the influence of different deposition sequences and heat treatment temperatures on the production of multilayered conversion coatings of silica and boehmite on 1020 carbon steel, aiming the improvement of the anticorrosive performance of alumina coatings in a saline medium. Thus, conversion coatings composed by different deposition sequences...
