Plating improves a material’s wear and corrosion resistance. Zinc, chromium, and nickel plating are common industrial applications and are thicker than those for aesthetic applications such as tin, brass, and silver. Platings may be added with or without the use of an electrical charge, depending upon the base material and type of plating. However, electroless plating provides a more uniform deposit, even on complex shapes. Depending upon the material, type of plating, its thickness, and part shape, post-plating machining may be necessary.
