Abstract

The main purpose of the paper is the determination of basic causes of non-conformances of anodised coating on aluminium finishing strips. Results of the analysis allow to identify factors that should be paid special attention during the production process. In the first part of the paper the analysis of quantitative parameters of anodised coating of finishing strips was presented. 20 finishing strips made of aluminium, previously submitted to the anodising process in sulfuric acid were evaluated. In each test, the same elements were used, each one was assigned the same number for each analysis. The parameters of layer were measured at 5 specific points. Three basic parameters of coating were examined: thickness, grindability and microhardness. The elements of statistical analysis were used for analysis. In the second part of the paper the Ishikawa chart was used to determine the causes of defects in the coating.
