Will the surface coating of PVD vacuum-coated faucets fade?

The surface coating of PVD vacuum-coated faucets is usually not prone to color fading and has strong durability for the following reasons:
Advantages of the process principle: PVD (Physical Vapor Deposition) deposits high-temperature ionic metals or compounds onto the surface of the substrate in a vacuum environment. The coating forms a molecular-level bond with the substrate rather than a simple adhesion, thus having extremely strong adhesion and being less likely to peel off or lose color due to friction or collision.
Stable material properties: Commonly used coating materials such as titanium nitride (gold), tungsten carbide (black), and diamond-like carbon (DLC, silver) are all highly stable compounds, and their oxidation resistance and corrosion resistance far exceed those of ordinary electroplating layers. For instance, titanium nitride coatings can withstand temperatures above 200℃ for a long time, and their salt spray test (simulating a humid corrosive environment) can last for over 1000 hours without discoloration, while ordinary chromium plating only takes 200 to 500 hours.

Daily maintenance impact: Under normal use, the PVD coating is not easily eroded by cleaning agents (such as neutral detergents) or moisture. However, it is necessary to avoid using strong friction or corrosive substances such as steel wool balls, strong acid or strong alkali cleaning agents, etc., to prevent damage to the dense structure of the coating surface. Long-term improper cleaning may increase the risk of color fading.
Special Circumstances Note:
If the coating thickness is insufficient (such as in inferior craftsmanship) or the substrate treatment is not standardized (such as surface oil stains not being completely removed), it may lead to a decrease in adhesion, and slight color fading may occur at the edges or corners after long-term use.
Some colored PVD coatings (such as rose gold and bronze) may slightly fade under extreme conditions (such as long-term exposure to sunlight or contact with strengthening chemical solvents) due to their higher process complexity, but the probability is much lower than that of baking varnish and ordinary electroplating processes.
High-quality PVD vacuum coating layers hardly fade under normal use and maintenance, making it one of the best choices for color endurance in current surface treatment processes. It is suitable for kitchen scenarios that pursue long-lasting beauty.
