What Is PVD Coating?
Physical Vapor Deposition (PVD) coating is a method of depositing a thin film of material onto a substrate through a vacuum deposition process.
PVD coating is used to improve the surface properties of a material, such as its hardness, wear resistance, chemical affinity, heat transmission, corrosion resistance, and visual appearance.
The PVD coating process involves the use of a vacuum chamber, where the source of the coating material, such as a metal or ceramic, is exposed to various energies, heat, ionic, arc. The coating material is evaporated and condenses onto the surface of the substrate to be coated, forming a thin film. The process is called physical vapor deposition because the coating material is deposited through a physical process, rather than a chemical reaction.
PVD coatings are commonly used in a wide range of industries, including manufacturing, Mold and Die, Aerospace, Automotive, Medical, and Tooling. Some examples of PVD coatings include titanium nitride (TiN), chromium nitride (CrN), zirconium nitride (ZrN), titanium aluminum nitride (TiAlN), aluminum titanium nitride (AlTiN), diamond-like carbon (DLC) and an infinite mixture of the previously mentioned coatings. These coatings can improve the performance and durability of components in a variety of applications, such as mold and die, cutting tools, engine components, and medical implants.
PVD coatings have several advantages over other coating methods, including high hardness, excellent adhesion, the ability to greatly reduce chemical affinity, and the ability to coat complex shapes and surfaces. They are also environmentally friendly, as they do not produce hazardous waste or use harmful chemicals.
