Metal coating is a process that involves applying a layer of metal onto a surface to enhance its properties. This technique is commonly used to improve corrosion resistance, wear resistance, and aesthetic appeal. Various methods, such as electroplating, hot-dip galvanizing, and thermal spraying, can be employed to achieve the desired coating. The choice of coating material often depends on the intended application. For example, zinc is frequently used to protect steel from rust, while chrome can provide a shiny finish and additional durability. Overall, metal coating plays a crucial role in extending the lifespan of metal products and components.
