Examples
Embodiment 1
[0056] In order to make the coating easier to peel off, in this embodiment, Ar gas and H 2 After degassing, the vacuum chamber 1 is preheated to a certain temperature to activate the ion energy of the coating, so that the coating atoms are more likely to get rid of the shackles of the coating matrix and peel off after being bombarded by gas ions.
Embodiment 2
[0058] In this example, on the basis of Example 1, the preheating temperature is controlled within the range of 300-400°C, and the heating time is controlled within 50 minutes to 70 minutes, so that the ion energy of the coating can be fully activated and maintained at Best state.
Embodiment 3
[0060] In this embodiment, in order to make the peeling process carry out in a stable vacuum environment, after vacuuming in step A, ensure that the pressure in the vacuum chamber 1 is less than 5×10 -2 Pa.
