Surface Finishing refers to a range of industrial processes applied to the surface of a material to improve its appearance, durability, corrosion resistance, or functionality. Common techniques include polishing, grinding, coating, plating, anodizing, and painting. These processes enhance the material's aesthetic appeal, smoothness, or performance, making it suitable for specific applications in industries like automotive, aerospace, electronics, and construction. Surface finishing can also provide protective layers, reduce friction, or prepare surfaces for further treatment.
