Problems solved by technology

However, there are few reports on the application of TiN film to the decoration industry by magnetron sputtering.
On the other hand, most of the current decorative TiN is only used for imitation gold plating, because the color of the coating is close to golden yellow, but the systematic research of TiN plating into other colors has not been reported.

Abstract

The invention provides a method for preparing a colorful TiN film by utilizing direct current magnetron sputtering. The method comprises the following steps: (1) based on high-peed steel as a substrate material, grinding the substrate material by respectively using a flint glass paper and then a crocus paper, and then polishing until the surface of the substrate material is of a mirror plane; (2) immersing the processed substrate material into an ethanol solution to carry out ultrasonic excitation for 10-20 minutes, carrying out dipping bath with acetone, and drying with a blower; (3) then fixing the substrate material on a specimen holder of a vacuum precipitation chamber for film coating, pumping the vacuum at the back bottom before film coating to 3*10<-3>Pa, and carrying out ion bombarding on the surface to clean for 3-5 minutes; and (4) plating different TiN film specimens under the different nitrogen flows (precipitation pressures). The result shows that the nitrogen flow (precipitation pressure) has an important influence on the color of a decoration coating film, and the color of the TiN film layer can be effectively changed through regulating the nitrogen flow. In the method, the film layer color required in practicable production through changing the nitrogen flow.

Description

[0001] Statement on funding research or development: This invention is funded by the Tianjin Normal University Academic Advancement Program (52X09038) and the Ministry of Education's research start-up fund for returning overseas students. technical field [0002] The invention belongs to the technical field of physical vapor deposition surface decoration coating treatment.
