A vast majority of materials used in engineering design, construction, and manufacturing activities involve the installation of a plating or coating system. In some cases, these coatings can be purely decorative, while in others they serve as a protective layer of some sort - to increase corrosion resistance, wear resistance, etc. As with other parts of the manufacturing process, it is important to understand the process of plating removal and re-plating. The goal of this essay is to discuss the basics of coating removal and re-coating.
The process of plating removal typically involves the use of some type of chemical etching or abrasive blasting technique. This will remove the material from the surface of the part, leaving it free of any unwanted plated material. Depending on the material being removed, and the surface finish desired, the appropriate etchant or abrasive should be chosen. Chemical etchants can usually be used when removing softer metals such as aluminum, while harder metals require the use of a more aggressive abrasive blasting material.
Once the plating is removed, the surface can then be prepared for re-plating. This involves thoroughly cleaning the surface of any debris or particles left behind during plating removal. This is usually done by chemical cleaning with a mild detergent and rinsing with de-ionized water. Additionally, depending on the type of re-plating that is desired, any desired surface treatments or coatings may need to be applied to the part prior to the plating process. Additionally, the parts may require an anodizing or electroplating step to prepare the surface for plating.
Once the part is prepared and ready for plating, the appropriate plating material is then applied. In most cases, an electroplating process is used, and the desired plating material is applied using an electric current. This process allows the plating to fill in recessed areas and crevices, resulting in an even, uniform plating coverage. Plating can also be done by heated baths or other chemical methods, depending on the desired material and finish.
Finally, once the plating is complete, it is important to properly maintain the parts so that the plating does not become damaged or deteriorate over time. Depending on the plating material, regular cleaning and lubrication may be required. Additionally, it is also important to inspect the parts for any signs of damage or corrosion. Performing regular maintenance on plated parts will ensure that they continue to provide the desired protection and look for many years.
In conclusion, plating removal and re-plating is an important part of many manufacturing, constructions, and engineering processes. The process involves etching, abrasive blasting, cleaning, coating, and plating of surfaces in order to achieve the desired end result. Properly maintaining plated parts can help ensure that they continue to provide the desired protection and look, and prolong the life of the part.
