PVD (Physical Vapor Deposition) coatings are indeed corrosion resistant.
These coatings are renowned for their durability and resistance to both corrosion and scratches.
The coating material in PVD is transferred at a molecular level.
This allows for precise control over the density, structure, and stoichiometry of the films.
This control enables the development of specific attributes such as adhesion, lubricity, and hardness.
5 Key Benefits of PVD Coating for Corrosion Resistance
1. Superior Corrosion Resistance
PVD coatings have been proven to exceed 1200 hours of neutral salt spray.
They also last over 150 hours in CASS (Copper-Accelerated Acetic Acid Salt Spray) tests on electroplated brass.
This demonstrates their high resistance to corrosion.
2. Tarnish Resistance
PVD coatings are highly resistant to tarnishing.
This makes them ideal for a wide range of decorative finishes that do not fade.
3. Enhanced Durability
The durability of PVD coatings surpasses that of other traditional finishes.
They are four times harder than chrome, making them highly scratch-resistant.
This hardness and scratch resistance contribute significantly to their corrosion resistance.
4. Strong Bonding
PVD coatings form a strong bond with the material they are applied to.
This makes 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.
5. Heat Resistance and Versatility
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.
