| Abstract: | Control technology of the sulfuric acid anodic oxidation film color black LC9CGS3 alumi- num alloy forging defect was studied. By optical microscope （OM） , scanning electron microscopy （SEM） and energy dispersive spectroscopy （EDS） analysis technology,studied the sulfuric acid a- nodic oxidation film color black LC9CGS3 aluminum alloy forgings defects formation mechanism. Results showed that the cause of black anodized color was due to improper heat treatment. By process test analysis, we obtained the chining process reengineering,, got a proved the product percent of pass. representation method of black anodized color defects.
