The Benefits of Passivation After Electropolishing Steel

The main reason why you need to passivate parts and machine components, is to enhance their corrosion resistance. When the process is done successfully it brings out satisfactory performance. When you carry out the process in the wrong way, the result is 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 process some contaminants may be transported to the stainless steel from the shop where the fabrication is taking place.

There is need to protect the stainless steel otherwise the contaminants can reduce its effectiveness. It can end up causing some corrosion attack on the steel. As a result you may get some result appearing on the machined parts. If you fail to protect the steel the most likely thing to happen is that some particles will stick to the iron. Even though the metal may appear shiny and clean some iron particles may cause corrosion after exposure to the air.

At the same time if the steel is not protected it can combine with sulfur particles. When this machine parts mix with sulfur they form some spots where corrosion will occur. Passivation is an important process that allows that corrosion does not take place. Therefore to ensure that you protect your metal from the corrosion process, you have to be sure that you receive through passivation. For you to make sure that you carry out a successful passivation process, you must be sure that the metal is free from any shop debris and any form of grease.

You must make sure that cleaning takes place before you start the process of passivation. If you avoid the cleaning process, the fat and the acid react to form bubbles on the surface that prevent the passivation process. That means the metal is not protected. That is what will cause corrosion later.

There are numerous ways of doing passivation, and the one used depends on the manufacturer. It will be good if you know some common mistakes that you need to avoid during the passivation of your metal. You should know that you do not pass your metal through passivation if it has been curburized. The metals so treated become vulnerable,and they can corrode when they are in the passivation process. Therefore if you want to be sure that your process will be successful, you must not do anything else to the metal after machining. You should make sure that the process of passivation is carried out before it is contaminated. That will make it possible to avoid corrosion.
