In the metal industry, the process of electropolishing is a common one. It is one many industry turn to in order to achieve a certain level of quality. It may be used before electroplating is performed. Overall, it is a means that is used to achieve a certain smooth end.
What Is Electropolishing?
Electropolishing is also referred to as electrochemical polishing or electrolytic polishing. It is a process through which a metal surface is smoothed out. It is the very opposite of electroplating which adds something since, in electropolishing, materials on the surface of the metal are taken away. Originally, the process was designed and used in the laboratory for specific metallurgical procedures. Electropolishing was the method through which metallurgical specimens were prepared for viewing beneath the microscope. Later, the procedure was adopted as a means of polishing stainless sheet metal as well as other stainless steel products.
When Is Electropolishing most Useful?
Electropolishing does have its purposes and advantages. However, like most metal processes, there are instances in which it excels. In fact, electropolishing is favored when it comes to irregular shapes. While many metal pieces are buffed to retain that smooth appearance, not all can be. When they are in odd and irregular shapes, electropolishing is the better and easier means through which to achieve the smooth, polished surface that is desired.
The method is also common and popular for complex shaped tools and items. Among such items are found:
* Washing achiness stainless steel drums
* Ultra high vacuum components
* Medical equipment
* Laboratory equipment
These are specialized tools that require the benefits that electropolishing can create.
Advantages of Electropolishing
Electropolishing does provide several benefits to the metal. Its application is intended to achieve certain and varied results including:
* Creates a passive surface
* Removes any surface roughness such as edge burrs that are the product of mechanical cutting tools
* Improves the appearance of the metal as well as its reflectivity
* Increases its ability to be corrosion free
* Prepares metal surfaces for plating, an oxidizing or conversion coating
* Removes any stressed and disturbed layers of surface metals the result of mechanical stock removal that teas, smears, and cuts
* Removes the results of any abrasive finishing process
* Takes away any of the surfaces that may be wanted for milling parts
Overall, electropolishing provides the manufacturer with a smoother, more corrosive free product. It is intended to give the metal item a better chance at becoming the end product that the company desires.
