Introduction to the vacuum plating equipment common vacuum coating method

Vacuum plating equipment is used for a class of need in the vacuum coating equipment, coating method is called vacuum coating method. Vacuum coating method is in the heart of the vacuum evaporating metals, alloys or compounds (or sputtering), make them deposited on the surface of the substrate, method. On the material surface plating a layer of thin film, can be material to... obtain some new chemical or physical properties. Vacuum coating method is a new coating process, also known as dry coating method, compared with the wet plating method, it has the features: 1, the film less susceptible to pollution, get good coating compactness, high purity. 2, wide range of membrane materials and the selection of base material, the film thickness can be controlled, with different vacuum plating equipment preparation of different functional thin film. 3, membrane layer and substrate adhesion, strong. 4, does not produce waste, not cause environmental pollution.
Common coating methods include vacuum evaporation, sputtering, ion plating, etc. These three coating methods have their advantages and disadvantages, including ion plating used most widely, its characteristic is: can plating materials including metals, alloys, compounds, such as membrane material evaporation method with evaporation and sputtering, membrane layer adherent strength is good, the plating film density high, uniform, can all plated surface.
