Embodiment 1
[0019] The workpiece made of No. 45 steel is ultrasonically cleaned with acetone for 5-30 minutes to remove oil, after rinsing, soak the workpiece with sulfuric acid with a concentration of 0.5-2.0% to remove the oxide film on the surface of the workpiece, and then rinse with tap water to remove acid Dehydrate by ultrasonic cleaning with ethanol. Put the workpiece into the vacuum chamber after drying, and pump the vacuum chamber to the back vacuum. Turn on the ion source, pass Ar gas into the vacuum chamber, and bombard the workpiece with energetic ions for 10-15 minutes to remove the oxide film on the surface of the workpiece.
[0020] Next, turn off the ion source and adjust the Ar flow rate to make the back vacuum reach the working pressure. Then, the evaporation source of Au is turned on, and the Au film is deposited to a thickness of 0.02 μm to form a metal that is not easily oxidized.
[0021] Next, turn off the Au evaporation source, continue to feed Ar gas, and heat ...

[0025] The workpiece made of No. 45 steel is ultrasonically cleaned with acetone for 5-30 minutes to remove oil, after rinsing, soak the workpiece with sulfuric acid with a concentration of 0.5-2.0% to remove the oxide film on the surface of the workpiece, and then rinse with tap water to remove acid Dehydrate by ultrasonic cleaning with ethanol. Put the workpiece into the vacuum chamber after drying, and pump the vacuum chamber to the back vacuum. Turn on the ion source, pass Ar gas into the vacuum chamber, and bombard the workpiece with energetic ions for 10-15 minutes to remove the oxide film on the surface of the workpiece.
[0026] Next, turn off the ion source and adjust the Ar flow rate to make the back vacuum reach the working pressure. Then, the evaporation source of Al is turned on, and an Al film is deposited to a thickness of 0.5 microns. The Al film is a metal capable of forming a protective oxide film.
[0027] Next, turn off the Al evaporation source, continue...
