What Research About Electropolishing Can Teach You

Why is it Important to Passivate after Electropolishing

Parts and components machined from stainless steel are supposed to be passivated in order to make them more resistant to corrosion. Carrying out the process in the right way makes the difference between failure and satisfactory performance. If the [practice is wrong it will cause corrosion. The method of passivation is mainly meant to maximize the inherent corrosion after fabrication of a particular piece to m stainless steel. There is, therefore, need to ensure the parts are passivated after either machining or forming fabricate them. Without passivation, it is possible t have some pollutants from the shop affecting the fabricated stainless steel.

There is need to protect the stainless steel otherwise the contaminants can reduce its effectiveness. That can cause some corrosion to the part. That may cause some places on the machined parts. It is possible to have some particles from the shop dust adhering to the stainless steel if it is protected. Although the piece of metal may seem clean and bright, that can soon change after exposing it to the atmosphere.

Something else that can happen to the stainless steel if exposed is to mix with sulfur particles. When this machine parts mix with sulfur they form some spots where corrosion will occur. With passivation process you will be sure that you have protected your metal pieces from corrosion. The best way to ensure that your fabricated metal is free from corrosion is to ensure that you also ensure you have taken it through passivation process. If you want to be sure you have a successful passivation process, you must make sure that you clean the metal thoroughly to remove grease and any other debris.

You must make sure that cleaning takes place before you start the process of passivation. If you happen to skip the cleaning process, the acid the and the grease will form bubbles on top of the metal and passivation will not take place. That is to say you will not have protected metal. As a result the metal will rust.

There are numerous ways of doing passivation, and the one used depends on the manufacturer. There are some common mistakes that you need to avoid when you are carrying out the passivation process. It is important to make sure that you do not take your metal through passivation if it has been carburized. You will have exposed such metal to corrosion that they can get from the passivation tank. Therefore if you want the process to be successful you have to be sure you have not done anything else to the metal after machining. You should make sure that the process of passivation is carried out before it is contaminated. That the way you can be sure that your metal will not suffer corrosion.
