The application of chemical plating and brush plating technology to the restoration of gilded copper objects was studied using scanning electron microscopy (SEM), X-ray diffraction (XRD) and other testing methods. It was found that the plating effect was good. After these studies, a series of conservation and restoration methods including stubble cleaning, filling, chemical plating, brush plating, corrosion inhibition and sealing were carried out on a defective gilded copper object, and the preparation of an independent accessory was also fulfilled. After the restoration, the object was complete in shape and harmonious in appearance, reproducing its aesthetic value.
