Corrosion Resistance

Hard and Durable PVD Coating protects the material surface for a long time even in extreme conditions and extends the material life by keeping it away from corrosive factors.

  1. Chromium Nitride (CrN): This coating is the preferred coating on stainless steel and offers excellent corrosion resistance.

  2. Titanium Nitride (TiN): TiN, a gold-coloured coating, is a popular coating used to improve corrosion resistance.

  3. Aluminum Titanium Nitride (AlTiN):It is an excellent option for both corrosion and oxidation resistance. It is also resistant to high temperatures.

  4. Zirconium Nitride (ZrN): This gold-coloured coating is particularly effective for corrosion and wear resistance.

  5. Diamond Like Carbon (DLC):DLC coatings offer high resistance to corrosion and also increase wear resistance by lowering the coefficient of friction.

  6. Titanium Aluminum Nitride (TiAlN): It is used for both corrosion resistance and high temperature oxidation resistance.

  7. Titanium Carbonitride (TiCN): Besides corrosion resistance, it also offers high hardness and wear resistance.

You can see examples from the areas where coatings with high corrosion resistance are used below. 

  • Automotive Components:In the automotive industry, PVD coatings are used to improve corrosion resistance on engine components, suspension parts and other critical components. This contributes to longer life and durability of vehicles.

  • Aerospace: Many metal components used in the aerospace industry are protected for long-term and safe performance by providing corrosion resistance with PVD coating.

  • Medical Devices and Implants: Medical implants and instruments must not corrode inside the human body. PVD coatings increase the corrosion resistance of these equipment, extending its biocompatibility and life.

  • Energy sector: Especially in subsea oil and gas drilling equipment, PVD coatings are used to provide corrosion resistance in salt water and other aggressive environments.

  • Electronic and Semiconductor: In electronic components and semiconductor manufacturing equipment, corrosion resistance is a critical factor for product life and reliability. PVD coatings can increase the corrosion resistance of these components.

  • Food Processing Equipment: Food processing equipment may be exposed to highly acidic or salty conditions. PVD coatings make these equipment more resistant to corrosion.

  • Marine: Watercraft and components are exposed to corrosion-inducing conditions such as salty sea water. PVD coatings can increase the corrosion resistance of these components.

These examples show how critical a PVD coating is to improve the corrosion resistance of materials. Choosing the right coating can vary depending on the needs of the application, the exposure environment and other factors.
