Abstract
(EN)
Provided are a noble metal product with a coating on the surface and a preparation method therefor. The noble metal product comprises a noble metal base (1) and a physical vapor deposition layer (2) attached to the surface of the noble metal base, wherein the noble metal is gold or silver. The preparation method of the noble metal product comprises: attaching a physical vapor deposition layer (2) to the surface of the noble metal base (1) by adopting physical vapor deposition. The finally prepared noble metal product may have various colors, a film layer is formed stable and is not easy to fall off, and during detection, the surface film layer of the noble metal product will not affect the fineness of the noble metal base.
