Physical Vapor Deposition (PVD) is a process used to create thin films or coatings on various surfaces. It involves vaporizing a solid material in a vacuum, allowing the vapor to condense on a substrate, forming a thin layer. This technique is commonly used in industries like electronics, optics, and manufacturing to enhance surface properties such as hardness, corrosion resistance, and electrical conductivity. PVD can be achieved through several methods, including sputtering and thermal evaporation. These methods allow for precise control over the thickness and composition of the deposited films. PVD is valued for its ability to produce high-quality coatings without the need for harmful chemicals, making it an environmentally friendly option.
