(1) Workpiece cleaning, racking, and entering the furnace Before the workpiece enters the furnace, it must undergo three processes of ultrasonic cleaning, pickling and rinsing.

The first is to put a metal cleaning agent prepared according to the requirements in the ultrasonic cleaning tank, and use ultrasonic to degrease and clean. After cleaning, pickling is performed, which can neutralize the residual lye during ultrasonic cleaning and can also act as an activation treatment. Then rinse to completely remove the acid solution. Rinse must use deionized purified water or distilled water. After three washings, drying is performed immediately. The temperature is generally controlled at about 100 ° C and the time is about 1h. It can also be blown into the oven immediately after being blown dry.

(2) Preparation before vacuum coating machine coating

① Clean the coating room of vacuum coating equipment. Clean the coating chamber of the vacuum coating equipment with a vacuum cleaner. When coating multiple times, the inner lining of the vacuum coating chamber needs to be cleaned regularly, usually once every half a month.

② Check the source of arc evaporation. Before work, make sure that the source of the arc evaporation source of the vacuum coating machine is installed correctly, the insulation is good, the pilot pin is controlled flexibly, the process is suitable, and it can just touch the cathode surface.

③ Check the insulation of the workpiece holder. The insulation between the workpiece holder and the ground of the vacuum coating machine must be good, and the contact point between the negative bias power source and the workpiece holder must be in good contact.
