摘　　要：利用扫描电子显微镜观察了镀铬板表面黑点缺陷形貌及其显微组织,应用x射线能谱仪和俄歇电子能谱仪分析了黑点成分,并结合机组实际工作状况对黑点缺陷的形成原因做了分析,在此基础上提出了镀铬板表面小黑点缺陷的控制措施。The morphology of black spot defect and its microstructure were Scanning Electron Microscope （SEM）, Energy Dispersive Spectrum （EDS）, Spectroscopy （AES） and microscope. The reasons for the formation of black analyzed, and the improving measures were suggested. studied Auger by using Electron spot defect were
