The color of stainless steel adornment board surface is rich and colorful, how does this color come after all?
It is found that this is all due to the vacuum ion deposition process of PVD. Through this process, the surface of the stainless steel plate can form a variety of colors, red, orange, yellow, green, blue, purple, you name it.
Vacuum ion coating coloring method is under the condition of high vacuum, heating metal to melt, evaporation, in stainless steel raw material surface cooling is heated metal to form a surface film processing method, commonly used metal is titanium and other low-melting metal. Stainless steel plate in the process of vacuum ion plating coloring, heating metal mainly has two methods, one is the use of resistance generated heat energy, one is the use of electron beam.
When carrying out coating film to stainless steel board chromatism, want to undertake processing processing to its surface above all, it is the stainless steel mirror board after polishing for instance, the drawing board after drawing silk is ground arenaceous, take out the passivating film of surface of former stainless steel board, still must undertake adjusting to time. Place of stainless steel plate in the vacuum chamber, choose some heating materials and titanium plating, with low voltage, high current arc discharge technology, by use of gas discharge from target material evaporation and evaporation occurs matter and gas ionization, using electric field acceleration, cause the evaporation material and the reaction product deposition on the workpiece.
Titanium metal in vacuum ion plating equipment and a variety of gases have a comprehensive effect to form plasma, after acceleration, plasma rush to the surface of the plated workpiece, forming a firm film layer. Stainless steel plate coated with titanium coating layer uniform, fine strong adhesion, high hardness, anticorrosive wear-resisting, good electrical conductivity and self-lubricating properties, colour and lustre is rich and varied at the same time, by adjusting the related parameters in the processing, can get a different color, so color stainless steel plating titanium plate is not only the golden, there are other colors can be customized according to customer requirements processing.
