This paper deal with the evaluation of quality of lacquered sheets with different pre-treatments after corrosive loading. Samples will be divided into groups according to the type and duration corrosion loadings. After exposure to corrosive salt mist corrosion chamber, the samples will be evaluated macroscopically according to relevant standards. Low degradation after all time corrosion load was on the sample pre-treated with an alkaline degreasing in combination with a yellow chromating and the samples pre-treated with an alkaline degreasing in combination with surface passivation. On these samples showed no loss of adhesion to the base material and the evaluation of delamination due to corrosion during loading had a low degree of degradation. Surfaces after the cross-cut test did not for both sets of samples after corrosion load all times no defects in the adhesion layer.
