5 Takeaways That I Learned About Electropolishing


Advantages of Passivating after Electropolishing

The smoothening and streamlining of metal objects is known as electropolishing. Passivating these surfaces after this process is highly important. Passivation is a chemical process that creates an oxide layer that protects stainless steel surfaces. This will protect these surfaces from corrosion and rusting. There is a cleaning cycle first when it comes to passivating. Passivating can help you remove oils, greases and any forming compounds. Lubricants, coolants and other residue left after electropolishing are removed through passivating.

After removing all these residues the metal parts are then placed into a passivation solution. There are passivating solutions that are very friendly to the environment. You must always consider time, concentration and temperature during the passivation process. The time for instance should not exceed two hours. The concentration and temperature are also specified. The types of the stainless steel are the ones that determines how well the passivation process will work. The process also has to be done by experts who are well trained and experienced. This is because they know all the potential hazards that may arise. There are practices that need to be followed when handling the passivation process. All the equipment used should all be safety equipment including special gloves and boots.

Avoid introducing steel parts and equipment during the passivating process. In this case you will avoid getting results that might be devastating. Hiring passivation professionals always comply with the set standards. There have to be water and air permits during passivation. You should also ensure that there are treatment capabilities. This process has to also pass all the industry specifications. All the boundaries in stainless steel are smoothened during the passivation process. The grain boundaries of stainless steel are the ones that are most vulnerable to corrosion. During manufacturing there are iron deposits that end up causing this. This iron is gotten rid of through passivation. If not removed it could later cause rust.

Another important aspect of passivation is that it forms an inert surface layer. This is the layer that is commonly known as an oxide layer. Most metals actually have an oxide layer that is naturally existent. This ensures that they are resistant to corrosion and rust. Passivation ensures that this oxide layer is thicker. The process of rusting and corrosion in this case actually becomes harder. Metal surfaces become more passive through passivation. This means they will not have to endure through the processes that eat away metals. Another advantage of passivation is that the results are always guaranteed. Passivating metals will improve the durability of metals because they will not be prone to corrosion and rusting. In conclusion the process of passivating after electropolishing is highly important and it has to be done.
