Passivation and electropolishing are finishing operations utilized by several industries that manufacture metal parts. Both the procedures use chemicals to remove foreign matter and free iron from stainless steel. However, there is a notable variation between the both. Electropolishing is nothing but a reverse plating technique applicable to any metal alloy. The procedure uses electrical current and a combination of a variety of chemicals that help in the removal of contaminants and surface imperfections. Achieving precise results with the help of electropolishing is possible.
The benefits that you receive
Electropolishing has enormous benefits and help in reducing corrosion on a broad spectrum of metal alloys. Although you will find the use of this method as a standard procedure for stainless steel, utilizing it as a corrosion resistance for other alloys is also an affirmative act. The effectiveness and versatility offered by this technique are replacing the process of passivation. A significant benefit that you will receive is when you are passing components using stringent salt spray and humidity tests. It is here that electropolishing comes to aid, as it removes the contaminants deeply embedded in the material. Additionally, the polishing is also helpful for machined parts, brazed assemblies, and other components that have an inadequate response to passivation.
Increasing the life of the metal part
Passivation is the standard procedure according to the standards that help in improving the life of the metal parts. However, the metal corrosion resistance provided by electropolishing is on the higher side when compared with that of passivation. If the metal parts that you manufacture require humidity and salt spray test with high waiting period, then choosing this is the answer. It not only helps in the removal of the contaminants from the material but also leaves the surface part clean and shiny.
The deciding factor
As you understood the difference between passivation and electropolishing, it is time for you to opt for a method that brings profit through a reputation for offering high-quality products. A better way to choose between the two procedures is by sending sample pieces of the components that you manufacture, to a trusted company involved in this job. They will perform the required tests on the parts and help you determine if this method is suitable for the components that you are producing.
As its benefits are on the higher side, it is preferable to consider the free sample testing on metal corrosion resistance offered by your electropolishing company. The process is irrespective of the size of the part that you are manufacturing and applies to different industrial applications such as consumer appliances, electronic industry, laser and photonics industry, aerospace industry, semiconductor industry, automotive industry, fire safety industry, dental industry, the pharmaceutical industry, medical device manufacturing, and marine industry. Not only will you be delivering high-quality products but also achieve a reputation for providing consistency in production, which attracts companies that often look out for reliable manufacturers. If you have further requirements based on your manufacturing needs, you can contact the company directly for additional details or request a quotation for the material/materials used for manufacturing.
