Vacuum evaporation coating
Vacuum evaporation coating is a process in which evaporating material is vaporized and deposited on the substrate surface to form a solid film under vacuum conditions.
Basic process flow of vacuum evaporation coating:
Preparation before plating → vacuuming → ion bombardment → baking → premelting → evaporation → taking part → surface treatment of film layer → finished product
