Do you know the function of vacuum coating processing?
Release time:
2022-05-23
Vacuum coating processing refers to the entire process of embedding a layer of other metals or aluminum alloys on the surface of certain metals using the basic principles of electrolysis. It is a PVD coating process that uses vacuum coating processing to attach a metal film to the surface made of metal or other raw materials, thus achieving effects such as preventing corrosion, improving wear resistance, conductivity, reflectivity, and aesthetics.

Vacuum Coating Process Effect
Vacuum coating utilizes the electrolytic effect to deposit a metal coating with excellent adhesion but different properties from traditional raw materials in a vacuum coating process. The constant pressure of the electroplated layer is more symmetrical than that of the hot-dip layer, generally thinner, ranging from a few micrometers to tens of μm. Depending on the electroplating, a surface layer with defensive decorative design and various multifunctional properties can be obtained on mechanical equipment crafts, repairing damaged steel parts and processing errors.
The coatings are mostly single metals or aluminum alloys, such as titanium targets, zinc, cadmium, gold or copper, brass, etc. They are also diffusion layers, such as nickel-silicon carbide, nickel-high-purity fluorinated graphite, etc. There are also cladding layers, such as copper-nickel-chromium layers on steel, silver-indium layers on steel, etc.
In addition to cast iron, steel, and stainless steel plates based on steel equipment, the conventional raw materials for electroplating also include non-ferrous metals, such as ABS plastics, polypropylene, polysulfone, and phenolic plastics. However, before vacuum coating, plastics must undergo unique activation and sensitization treatments.
That is, it utilizes the basic principles of electrolysis to embed a layer of color spectrum on the surface of certain metals. During vacuum coating, the metal to be plated is anodically oxidized and oxidized by air into cations, which then Enter the plating solution; the metal workpiece to be plated serves as the cathode, and the cations of the metal to be plated are reduced on the metal surface, producing a coating.
In order to eliminate the influence of other cations and make the coating uniform and firm, Vacuum Coating Process an aqueous solution containing the cations of the coating metal should be used as the plating solution to keep the concentration of the coating metal cations constant.
