Unterschied zwischen Galvanik und Vakuumbeschichtung

1、 Unterschiedliche Prinzipien

1)Galvanik: der Prozess des Plattierens einer dünnen Schicht anderer Metalle oder Legierungen auf der Oberfläche einiger Metalle, basierend auf dem Prinzip der Elektrolyse. It is a process of making a layer of metal film on the surface of metal or other material parts by electrolysis. The electroplating process is a process in which the metal ions in the plating solution are reduced to metal atoms through the electrode reaction under the action of external electric field, and the metal is deposited on the cathode.

2)Vacuum plating: various metal and nonmetal films are deposited on the surface of plastic parts by distillation or sputtering under vacuum.

2、 Different process characteristics

1)Galvanik: it can prevent metal oxidation (such as corrosion), improve wear resistance, conductivity, reflectance, corrosion resistance (copper sulfate, etc.) and enhance aesthetics.

2)Vacuum plating: in this way, a very thin surface coating can be obtained. Zur selben Zeit, it has the outstanding advantages of fast speed and good adhesion, but the price is also high, and there are fewer types of metal that can be operated, which is generally used as the functional coating of higher grade products.
