Summary

Explorative factor analysis is applied to measurements of a chromated aluminium alloy to describe the paint adhesion and corrosion of samples with different coating thickness. Interpretation of various measurements is difficult as the surface behaviour of the material is a superposition of complex interactions. Factor patterns of the measurements describe the independent information contained in the data, the factor scores are used to give an objective classification of the samples. The factor analysis explains the superposition of the protective effect of coating thickness and the destructive effect of defect sites in the coating.
