PVD coatings are highly resistant to rust and corrosion, making them suitable for various applications in harsh environments.
These coatings are applied as a thin, durable layer that adheres strongly to the base material.
This enhances its resistance to corrosion, scratching, and environmental factors such as saltwater and ultraviolet light.
5 Key Reasons Why PVD Coatings Resist Rust and Corrosion
1. Corrosion Resistance
PVD coatings, which include carbides, nitrides, and oxides of metals, are more chemically inert than their pure metallic forms.
This chemical stability ensures that products coated with PVD, such as faucets, door hardware, and smartphones, maintain a tarnish-free appearance for years.
The resistance to corrosion is particularly beneficial in marine environments and coastal areas where exposure to saltwater can accelerate rusting.
2. Durability and Adherence
The PVD process involves creating a micron-thick layer of coating that interpenetrates with the underlying material, preventing it from flaking or chipping off.
This strong adherence not only enhances the durability of the coating but also its resistance to wear and tear.
Unlike other coating methods like anodizing, paint, or powder coating, PVD uses Diamond-Like Carbon, which is blasted onto metal surfaces and rapidly cooled, resulting in a more robust and scratch-resistant finish.
3. Environmental Stability
PVD coatings are also resistant to prolonged exposure to ultraviolet light, which can degrade other types of coatings over time.
This resistance ensures that the coated products maintain their aesthetic qualities and functionality even when exposed to direct sunlight for extended periods.
Additionally, the high abrasion resistance of PVD coatings means they can withstand mechanical stresses without degrading, further enhancing their longevity and effectiveness in preventing corrosion.
4. Chemical Inertness
The chemical inertness of PVD coatings ensures that they do not react with environmental factors, making them highly resistant to rust and corrosion.
This property is particularly useful in environments where chemical exposure is common, such as industrial settings or coastal areas.
5. Enhanced Longevity
The combination of strong adherence, chemical inertness, and environmental stability ensures that PVD coatings maintain their effectiveness over time.
This enhanced longevity makes them ideal for protecting valuable assets in harsh or corrosive environments.
