Chrome Plating Knowledge Introduction (2)
Chrome plating offers some special advantages in terms of performance and appearance. It’s a hard finish that offers excellent corrosion resistance and resistance to abrasion. It also allows for a low-observation, highly reflective finish. Chrome plated finishes also allow for an increased finish without the need for additional maintenance.
Although chrome plating is widely used, it can be an expensive process, due to the costs associated with the initial plating costs, the amount of work and materials involved, as well as the maintenance and periodic refinishing associated with chromium plating.
The process of chrome plating involves several steps involving the application of various chemicals and the use of electroplating techniques. It is important to understand the techniques and processes involved in order to achieve the best plating results possible.
The process of chrome plating begins with metal preparation. This includes cleaning and treating the metal surface to remove oxidation, scale, paint and other contaminants which can affect the adhesion of the chromium plating. Metal polishing may also be necessary to achieve the desired surface contamination level on the metal.
Once the metal has been prepared, it is ready for chromium deposition. This is usually done through one of two processes – either electroplating or electrolytic plating.
Electric plating involves the use of a special bath containing chromium salts and other special additives. Electric current is passed through the bath and through the metal, which causes the chromium ions to transfer onto the metal surface. This process is highly efficient and fast, and results in a very bright and shiny finish.
Electrolytic plating also involves the use of a special bath containing chrome salts, but the metal surface must be attached to one electrode in the bath. An electric current is then passed through the bath, and the chrome ions are transferred to the metal surface. The current level and time must be carefully monitored to ensure the ideal chromium finish.
Once the chromium has been added to the metal surface, it is then ready for buffing and polishing. This polishing is important to achieve the final look desired. It is important to use buffing compounds that are safe and compatible with chrome plating, as incompatible compounds can have adverse effects on the plating.
Chrome plating is a relatively simple process, but important considerations should be kept in mind when plating. The quality of the finish depends largely on the metal preparation before plating, as well as the quality of the buffing and polishing. Following proper guidelines and procedures are essential to ensure the best chrome plating results possible.
