PVD plating involves the use of a variety of materials to enhance the durability, wear resistance, and performance of the substrate they are applied to.
What Materials are Used in PVD Plating? (7 Key Materials Explained)
1. Titanium and Titanium Compounds
Titanium is a common material used in PVD plating due to its strength and resistance to corrosion. Titanium nitride (TiN) is particularly popular for providing wear protection and is widely used in applications such as coating machine tools. Titanium carbide (TiC) and titanium carbonitride (TiCN) are also used for their hardness and wear resistance.
2. Zirconium and Zirconium Compounds
Zirconium and its compounds like zirconium nitride (ZrN) and zirconium oxide (ZrO2) are used in PVD coatings for their high-temperature stability and resistance to wear and corrosion. These materials are often used in applications where high durability is required, such as in aerospace and automotive industries.
3. Aluminum and Aluminum Compounds
Aluminum and aluminum oxide (Al2O3) are used in PVD coatings for their excellent electrical and thermal properties. Aluminum is often used in electronic circuitry due to its conductivity, while aluminum oxide is used for its insulating properties and durability.
4. Stainless Steel and Copper
Stainless steel and copper are used in PVD coatings for their aesthetic qualities and corrosion resistance. Stainless steel is often used in decorative applications, while copper is used in electronics for its high conductivity.
5. Diamond-like Carbon (DLC)
DLC coatings are known for their extreme hardness and low friction coefficient, making them ideal for applications requiring high wear resistance and low friction, such as in automotive components and cutting tools.
6. Other Materials
Other materials used in PVD plating include MCrAlYs (a class of superalloy materials used for high-temperature applications), and various aluminides which are used for their resistance to high temperatures and corrosion.
7. Deposition Techniques
These materials are applied using techniques such as electron beam evaporation and ion plating, which allow for precise control over the deposition process, ensuring uniform and consistent coatings. The choice of material and deposition technique depends on the specific requirements of the application, such as wear resistance, corrosion resistance, electrical conductivity, and aesthetic qualities.
