What are the different surface treatment processes commonly seen on Brass Basin Faucets in the market?

The surface treatment processes commonly seen on Brass Basin Faucets in the market are mainly the following:
Electroplating:
Electroplating is a surface treatment technology that covers a layer of metal or alloy on the surface of brass. Common electroplating layers include chrome, nickel, etc.
The electroplated chrome layer has corrosion resistance, wear resistance and decorative properties, and can provide long-lasting gloss and protection for the faucet.
The electroplated nickel layer has good rust resistance and wear resistance, which can effectively extend the service life of the faucet.
Spraying:
Spraying is a process in which the paint is evenly applied to the surface of the brass faucet through a spraying device.
The spraying layer can provide a rich color selection and good decorative effect, making the faucet more beautiful.
The spraying material usually chooses wear-resistant and corrosion-resistant coatings to improve the durability of the faucet.
Polishing:
Polishing is to remove the uneven parts of the surface of the brass faucet by mechanical or chemical methods to achieve a smooth and bright effect.
The surface of the polished faucet is as smooth as a mirror, with high decorativeness and tactile comfort.
However, the surface of the polished faucet is soft and easily scratched and worn, so it needs to be maintained.
PVD (Physical Vapor Deposition):
PVD technology forms a strong, wear-resistant and corrosion-resistant coating by evaporating and depositing metal or alloy on the surface of the brass faucet in a vacuum environment.
PVD coating has weather resistance, corrosion resistance and wear resistance, and can maintain the appearance and performance of the faucet for a long time.
PVD coating also has good environmental protection and is a green and environmentally friendly surface treatment technology.
Oxidation blackening:
Oxidation blackening is a surface treatment process that forms a black oxide film on the surface of the brass faucet by chemical methods.
The surface of the faucet after oxidation blackening is deep and elegant, and has high decorativeness.
However, the corrosion resistance and wear resistance of the oxidation blackening layer are relatively weak, and it is necessary to pay attention to maintenance during use.
Summary: The above surface treatment processes have their own characteristics, and the appropriate surface treatment process can be selected according to different use environments and needs. Electroplating and spraying processes are more common in the market, with corrosion resistance, wear resistance and decorative properties; the polishing process focuses on appearance and tactile comfort; the PVD process is favored for its weather resistance, corrosion resistance and wear resistance; and the oxidation blackening process is loved by some users for its unique decorative properties.
