采用图像扫估方法获得了碳钢、低合金锅实海试片的腐蚀形貌图像，井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-So assessment methods used to obtain images of the carbon steel, low alloy pot real sea test piece corrosion morphology images, image pre-processing well, and gray-scale analysis of samples from the distribution of gray value and the corresponding corrosion morphology as a Knowledge Base standard samples, using fuzzy pattern recognition theory to establish the corrosion morphology of diagnostic systems, can be scanned to determine the distribution of gray value of metal surface corrosion morphology
