Influence of Metal Finishing Techniques on the Properties of the Electroplated Surface
Metal finishing techniques are used after electroplating to modify the surface properties of the electroplated material. Common post-electroplating metal finishing techniques include polishing, buffing, sanding, and anodizing. Each of these techniques has a different application and outcome.
Polishing is typically used to improve the surface finish and remove any unevenness or imperfections. It involves the use of abrasive materials and machinery to work the surface of the metal until the desired finish is achieved. Buffing is similar to polishing, but uses a softer abrasive material and a gentler machine. It is often used to create a shiny finish on the metal. Sanding, on the other hand, is used to remove rust, scale, and other contaminants from the surface of the metal. It is usually done with a mixture of sandpaper and a rotary tool.
Anodizing is a more complex finishing technique that is used to enhance the corrosion resistance and wear resistance of the metal. It involves electrolytically coating the metal with a layer of oxidation. This layer of oxidation improves the durability of the metal and makes it more resistant to wear and tear.
The different metal finishing techniques used after electroplating have a significant impact on the properties of the electroplated surface. Polishing, buffing, and sanding can all improve the surface finish of the metal, while anodizing can improve the corrosion and wear resistance of the metal. Depending on the desired outcome, different techniques may be used to get the desired results.
