Abstract The theory of fractal geometry is used to analyze the corrosion morphology images, which were acquired by scanner. The fractal dimension, generalized dimension, area factor and laucinarity of metallic corrosion images of samples that exposed in seawater were calculated. Taking the obtained characters of metallic samples and their corrosion modality as the knowledge base, the diagnosing system identifying corrosion modality of metallic material in seawater was established according to the theory of fuzzy pattern recognition. The morphology of corrosion images can be identified by acquired fractal characters.

Key words: corrosion morphology fractal
