What is the difference between vacuum degree and electroplating?

March 13, 2024

Vacuum Coating: vacuum coating is a technique that uses physical or chemical processes to evaporate or sputter materials onto the surface of a workpiece in a vacuum environment to form a thin film. Vacuum plating can form functional coatings such as metal films, oxide films, and nitride films on the surface of workpieces through methods such as evaporation, sputtering, and ion plating. Vacuum plating coatings have high hardness, wear resistance, and corrosion resistance, and are commonly used to improve the appearance of workpieces, increase surface hardness, or enhance wear resistance.


Applicable scenario: vacuum plating is suitable for fine processing of workpiece surfaces, such as optical lenses, watch cases, mobile phone cases, and other products that require special appearance requirements.


Electroplating: electroplating is a technique that uses electrolysis to deposit metal ions onto the surface of a workpiece to form a metal coating. By electroplating with the workpiece as the cathode and the metal solution as the anode in the electrolytic cell, a uniform metal coating will be formed on the surface of the workpiece, improving its corrosion resistance, conductivity, and other properties. Electroplating usually includes common metal coatings such as chromium plating, nickel plating, and copper plating.


Applicable scenarios: electroplating is widely used for surface protection and decoration of various metal products, such as automotive parts, furniture hardware, and other products that need to improve surface smoothness and corrosion resistance.
