The fine oxidative layer that passivation produces is very durable, but it can be removed. When a passivated metal undergoes repeated abrasion from polishing, sandblasting, or maintenance, it can expose free iron on the surface. This is why passivation is…

Although chemical passivation is not considered the most efficient means of finishing material, it’s not always possible to do it through electropolishing. Items that cannot be taken offsite or are too large to use an electrical current for polishing are clear…

When referring to metals like steel or aluminum, a material is passive when it does not react to oxygen or water. A passivated material has been treated with a chemical process to remove iron. After the iron is removed, the…

The type of passivation you need will vary according to the type of metal you are using and how it will be applied. Chemical passivation can be adjusted to any of the most commonly used metals to achieve a fine…

Passivation can mean the success or failure of a device. For example, in the medical and pharmaceutical industries, passivation plays an essential role in protecting the health of patients and consumers. Device passivation is used to protect asthmatic drugs from…
