Physical Vapor Deposition (PVD) coating technology is an advanced surface treatment method that involves heating a target material (usually metal or alloy) to a high temperature in a vacuum chamber, causing it to evaporate or sputter, and then forming a uniform and dense film on the surface of the substrate. With the rapid advancement of technology in recent years, PVD coating technology has been widely used in many fields. This article will delve into PVD coating technology to explore how it achieves superior surface treatment and performance enhancement.
