Physical vapor deposition (PVD) is a process used to create a thin but durable metal coating on various surfaces, including sanitary ware like faucets,hand and head showers, and bathroom fixtures. PVD coatings provide a range of benefits such as improved hardness, scratch resistance, and aesthetic appeal.
These coatings are created in a vacuum environment where metal atoms are evaporated and then condensed onto the surface of the object being coated. This process results in a thin film of metal that adheres well to the substrate and can be used to create a variety of finishes, including chrome, gold, bronze, and black.
Background
Faucets as important consumption of our daily life, consumers and manufactures are more focusing on the creative design & surface treatment process. PVD finish is more welcomed due to its low production cost, environmentally friendly, extremely durable, highly brilliant, and guaranteed for life against tarnishing advantages.
PVD is short name for Physical Vapor Deposition. This process creates a ionized thin films to the faucet resulting in the most durable finish available today. Products with PVD finish will not corrode, discolor, or tarnish.
Faucets with PVD finished last longer life time, can pass the Neutral salt spray test over 200 hours.
The PVD process typically involves the following steps:
Cleaning: The surface of the sanitary ware is thoroughly cleaned and prepared to ensure good adhesion of the PVD coating.
Vacuum Chamber: The sanitary ware is placed in a vacuum chamber along with the metal that will be used for the coating.
Evaporation: The metal is heated in the vacuum chamber, causing it to evaporate and form a vapor.
Deposition: The metal vapor condenses onto the surface of the sanitary ware, forming a thin and uniform coating.
Finishing: After the coating process is complete, the sanitary ware may undergo further finishing processes to enhance its appearance and durability.
PVD coatings on sanitary ware are known for their durability, resistance to corrosion, and ability to maintain their finish over time. They are commonly used in high-end bathroom fixtures to provide a luxurious and long-lasting appearance.
