What is PVD coating?

PVD coating (Physical Vapor Deposition) is a technology used to coat surfaces with various materials. PVD operates on the principle of evaporating a solid material under high vacuum, allowing the vapor to collide with and deposit on the target surface.

During the PVD coating process, typically metals or metal compounds are used. These materials are subjected to electron bombardment, known as a cathode, and heated under high vacuum to evaporate them. The evaporated materials collide with the target surface, accumulating to form a thin film.

PVD coating is a widely used surface treatment in many industries. This coating method offers several advantages. Firstly, the coating process is carried out at low temperatures, which preserves the properties of certain materials. Additionally, the coating films are often hard, smooth, and resistant to wear. Therefore, PVD coating is preferred for various purposes such as reducing friction, preventing wear, increasing surface hardness, providing protection against corrosion, and for decorative purposes.

PVD coatings can be applied to various materials such as metals, ceramics, and plastics. Examples include its usage in watches, jewelry, automotive parts, cutting tools, optical coatings, medical devices, and electronic components.

However, the PVD coating process can be complex and costly. Additionally, coating large-sized parts can be challenging. Therefore, it is important to correctly apply the coating process and ensure that the facility where the process takes place has the appropriate equipment.
