Yes, PVD (Physical Vapor Deposition) coatings are corrosion resistant. PVD coatings are known for their durability and resistance to corrosion and scratches. The coating material used in PVD is transferred at a molecular level, allowing for a high level of control over the density, structure, and stoichiometry of the films. This enables the development of specific attributes such as adhesion, lubricity, and hardness.
PVD coatings have been shown to surpass 1200 hours of neutral salt spray and over 150 hours CASS (Copper-Accelerated Acetic Acid Salt Spray) on electroplated brass, indicating their high resistance to corrosion. They are also highly resistant to tarnishing, making them suitable for a wide range of decorative finishes that do not fade.
The durability of PVD coatings is superior to other traditional types of finishes, and they are four times harder than chrome, making them highly scratch-resistant. This hardness and scratch resistance contribute to their corrosion resistance, allowing them to withstand harsh environments and wear.
PVD coatings have a strong bond with the material they are applied to, which helps make the product stronger and more corrosion-resistant compared to coatings applied through other electroplating processes. The thinness of the PVD coating ensures that the product retains its original shape while providing a rich finish and color.
Additionally, PVD coatings are heat-resistant, meaning they can withstand high temperatures without damaging the surface of the material. They are versatile and can be applied to almost any inorganic and organic material. Moreover, PVD coatings are considered more environmentally friendly compared to electroplating or painting processes.
In conclusion, PVD coatings are highly corrosion resistant due to their durability, scratch resistance, and the ability to control the density, structure, and stoichiometry of the films. They can withstand harsh environments, adhere strongly to the material, and provide a barrier against damage.
