摘　　要：采用图像扫描方法获得了碳钢、低合金钢实海试片的腐蚀形貌图像，并对图像进行预处理及灰度分析；将所得样本的灰度值分布和对应的腐蚀形貌作为知识库的标准样本，用模糊模式识别理论建立了腐蚀形貌诊断系统，可以由扫描灰度值分布判断金属的表面腐蚀形貌．The corrosion images of metallic material in seawater which are acquired by scanner are pre-processed and grey analysis method is used to analyze them. Taking the grey distribution 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 images can be identified by grey distribution.
