Coating processes involve applying a layer of material onto a surface to enhance its properties, such as durability, appearance, or resistance to corrosion. Common methods include spraying, dipping, and electroplating, each suited for different applications and materials. These processes are widely used in industries like automotive, aerospace, and electronics to protect components and improve performance. The choice of coating material can vary, including options like paints, powders, and metals. Factors such as the intended use, environmental conditions, and desired finish influence the selection. Proper surface preparation is crucial for ensuring good adhesion and effectiveness of the coating, leading to longer-lasting results.
