Coloring Method Of Colored Stainless Steel Sheet
How is the colored stainless steel sheet colored, and why can its surface color be so colorful? In fact, this is all the credit of the PVD vacuum ion plating process. Through this process, various colors can be formed on the surface of the stainless steel plate, such as red orange, yellow, green, blue, and purple, which has expanded its application field.
The coloring method of vacuum ion plating film is a processing method of heating the metal to melt and evaporate under the condition of high vacuum, and cooling the heated metal on the surface of the stainless steel raw material to form a surface film. Commonly used metals are low-melting metals such as titanium. There are two main methods for heating the metal during the vacuum ion plating and coloring process of stainless steel. One is to use the heat generated by the resistance, and the other is to use the electron beam.
When coating and coloring the stainless steel sheet, the surface must be processed first, such as the polished stainless steel mirror panel, the wire drawing plate after brushing and frosting, etc., to remove the passivation film on the surface of the original stainless steel plate, and the time must be performed Adjustment. Put the stainless steel plate in the vacuum chamber, select some heating materials to be plated and titanium metal, adopt low-voltage, high-current arc discharge technology, use gas discharge to evaporate the target material and ionize the evaporated substance and gas, and use the acceleration of the electric field Function to deposit the evaporated substance and its reaction products on the workpiece.
Titanium metal interacts with various gases in the vacuum ion plating equipment to form plasma. After acceleration, the plasma rushes to the surface of the workpiece to be plated to form a firm film. The titanium coating of stainless steel plate is fine and uniform, strong bonding force, high hardness, anti-corrosion and wear resistance, good electrical conductivity and self-lubricating performance, and rich and diverse colors. By adjusting the relevant parameters in the processing process, different colors can be processed. Therefore, the color stainless steel titanium-plated gold plate is not only golden yellow, but also other colorful, which can be customized according to customer requirements.
