Embodiment 1
[0024] see Figure 1-2 , the present invention provides a technical scheme: the preparation process of champagne gold coating, comprising the following steps:
[0025] S1: Provide the metal sheet to be processed, put it into the vacuum chamber, and vacuumize the vacuum chamber. During the vacuuming process, ensure that the indoor air pressure is 6 -1 Pa, while the coating process remains unchanged;
[0026] S2: Ensure that the air pressure in the vacuum chamber is stable, start the high-voltage transformer, turn on the bombardment power supply, and control the current value within the range of 30 A. The air is ionized into plasma in the state of discharge, and the workpiece is bombarded, cleaned and activated;
[0027] S3: Use the reactive magnetron sputtering coating process to co-sputter with titanium and aluminum alloys as the target, and use nitrogen and acetylene gas as the reactive gas for coating. The reaction time is 120 minutes and the reaction temperature is 100 de...
Embodiment 2
[0030] The preparation process of champagne gold coating includes the following steps:
[0031] S1: Provide the metal sheet to be processed, put it into the vacuum chamber, and vacuumize the vacuum chamber. During the vacuuming process, ensure that the indoor air pressure is 6 -1 Pa, while the coating process remains unchanged;
[0032] S2: Ensure that the air pressure in the vacuum chamber is stable, start the high-voltage transformer, turn on the bombardment power supply, and control the current value within the range of 38 A. The air is ionized into plasma in the state of discharge, and the workpiece is bombarded, cleaned and activated;
[0033] S3: Use the reactive magnetron sputtering coating process to co-sputter with titanium and aluminum alloys as the target, and use nitrogen and acetylene gas as the reactive gas for coating. The reaction time is 120 minutes and the reaction temperature is 100 degrees Celsius, and finally a champagne gold film is formed on the surface...
