passiivaatio
Passiivaatio is a process that reduces the reactivity of a material, typically a metal, by forming a protective film on its surface. This film, often an oxide or nitride layer, acts as a barrier, preventing further chemical reactions such as corrosion. The term "passivity" refers to this state of reduced reactivity.
The mechanism of passivation often involves exposure to an oxidizing environment. For example, stainless steel spontaneously
Passivation is a crucial surface treatment in many industries. In the medical device industry, it is used
