The invention discloses a method for judging the corrosion resistance of an amorphous carbon coating, which comprises the following steps of: representing internal pore defects of the amorphous carbon coating by adopting a small-angle X-ray scattering technology, analyzing scattering data by utilizing analysis software to obtain a scattering intensity and scattering vector curve, and evaluating the corrosion resistance of the amorphous carbon coating by taking the relationship between the scattering intensity and the scattering vector as an evaluation index. And judging the corrosion resistance of the amorphous carbon coating. According to the method, effective detection and statistics of the nanoscale pore defects are realized, qualitative correlation between the pore defects of the amorphous carbon coating and the corrosion resistance is established, the gap in characterization of the pore defects of the amorphous carbon coating can be filled, and the method can be directly used for comparison and judgment
