Abstract

The invention discloses a composite film and a film plating method thereof. The surface of a metal base material is plated with the composite film and the composite film comprises a metal chromium layer, a metal titanium layer, a titanium nitride layer, a chromium-titanium mixing metal nitride layer and a chromium mixing metal nitride layer successively from the metal base material to outside. The plating method thereof comprises the following steps: plasma treatment is performed on the metal base material to enhance the surface activity of the metal base material; the surface of the metal base material is plated with the metal chromium layer, the metal titanium layer, the titanium nitride layer, the chromium-titanium mixing metal nitride layer and the chromium mixing metal nitride layer successively; after the film plating, heating is stopped and the plated metal base material is taken out when the metal base material is cooled to below 100 DEG C. Modification treatment is performed on a simple-substance metal film to enhance the abrasive resistance and the corrosion resistance of the surface of the metal base material and keep long-term appearance beauty and value of the metal base material. The adhesive force and the mechanical resistance strength of the film are good. In addition, the film resistance is low, thus the conductivity performance of the metal surface is not affected.

Description

technical field [0001] The invention belongs to the technical field of metal material surface treatment, in particular to a composite thin film coated on the surface of a metal substrate and a coating method thereof. Background technique [0002] As a symbol of wealth, gold is widely used in various luxury goods, such as mobile phones, watches, necklaces, rings, etc. Usually, the surface is plated with a certain quality of gold to increase the value of the product. However, the material of gold itself is soft, easy to wear, and it is also easy to become very fine powder. In addition, decorative products are generally worn on the body, so that the gold-plated layer will be worn after a long time. Therefore, it is necessary to modify the simple gold film to enhance its wear resistance and maintain its appearance beauty and long-term value. Contents of the invention [0003] In order to overcome the deficiencies in the prior art referred to above, the present invention provi...
