Springs are usually finished with some type of coating, plating, or finishing process. In finishing processes, the spring’s surface undergoes additional steps to help combat erosion, lend new properties to the spring, or simply improve the spring’s overall appearance. Some examples of common finishing processes include the following:

• Shot peening: Shot peening is a finish applied to cold-worked springs. In this process, spherical shots are shot at the wire, resulting in compression stress and forming layers of compression dimples. As a result, the material’s surface hardens, making it more resistant to fatigue, corrosion, and cracking.
• Plating: Plating occurs when a thin layer of metal is applied to the surface of the spring or wire form. This is usually accomplished through an electroplating process where chemicals and electrical currents bond the plating metal to the surface of the spring wire. When complete, platings can provide improved corrosion resistance and strength. Platings may also improve the spring’s physical or aesthetic properties. For example, copper and gold platings lend improved electrical conductivity for electronic and power applications, while nickel and cadmium platings provide a chrome finish.
• Powder coating: Powder coating is another option for wire spring finishes. Powder coatings are usually applied to hot-drawn springs and help prevent rust from forming on the spring’s surface. Coatings may also come in a range of colors for aesthetics.
