Why it is Important to Passivate after Electropolishing

The smoothening and streamlining of metal objects is known as electropolishing. After electropolishing it is very important to passivate these surfaces. Passivation is a chemical process that creates an oxide layer that protects stainless steel surfaces. This ensures that these surfaces do not rust or corrode. There is a cleaning cycle first when it comes to passivating. Any forming compounds like oils and greases are normally removed through passivating. Lubricants, coolants and other residue left after electropolishing are removed through passivating.

The metal parts are then placed into a passivating solution after the residues are removed. You can choose the passivating solutions that are eco-friendly. Time, concentration and temperature are important aspects that must be considered during the passivation process. The time for instance should not exceed two hours. The concentration and temperature are also specified. The passivation process works well based on the type of stainless steel. The passivation process is only performed by trained and experienced experts. In this case they are aware of all the potential hazards that may arise. When the passivation process is happening there are safety processes that need to be followed. All the equipment used should all be safety equipment including special gloves and boots.

When passivating there should no introduction of steel parts or equipment. You will ensure that you will not get frustrating results. Hiring passivation professionals always comply with the set standards. There have to be water and air permits during passivation. There also has to be treatment capabilities put in place in this case. This process has to also pass all the industry specifications. A major advantage of passivation is that it smoothens all the boundaries in stainless steel. The grain boundaries of stainless steel are the ones that affected by corrosion mostly. During manufacturing there are iron deposits that end up causing this. Passivation helps in getting rid of this iron. 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 have a naturally existing oxide layer. This ensures that they are resistant to corrosion and rust. Through passivation there is thickening of the oxide layer. The process of rusting and corrosion in this case actually becomes harder. Through passivation metal surfaces normally become passive. This means they are less likely to suffer from natural chemical processes that eat away metals. Another importance of passivating metals after electropolishing is that you will get guaranteed results. Metal surfaces are durable after passivating because they are not affected by corrosion and rusting. The process of passivating is very important as you will get to enjoy various benefits.
