Passivating: meaning, definitions and examples
🛡️
passivating
[ ˈpæsɪveɪtɪŋ ]
chemical process
Passivating refers to a chemical process that makes a material less reactive by coating it with a protective layer. This term is commonly used in metallurgy to describe the treatment of metals that forms a passive film, increasing resistance to corrosion.
Synonyms
dulling, inhibiting, neutralizing
Examples of usage
- The technician is passivating the stainless steel to prevent rust.
- Passivating aluminum improves its durability in harsh environments.
- We are passivating the metal parts after cleaning to ensure longevity.
- Passivating the surface can enhance the bond strength for coatings.
Etymology
The term 'passivate' originates from the Latin root 'passivus', which means 'to suffer' or 'to be acted upon'. Initially, in the early 20th century, the term came to be associated with materials that undergo a state of reduced reactivity, particularly metals that develop a protective oxide layer in reactions with their environments. The process of passivation has been increasingly relevant in various fields, including chemistry, metallurgy, and material science, where it aims to enhance the lifespan and integrity of materials under environmental stress. The use of the word 'passivating' as a verb reflects the transition of the word into practical applications in industries where the prevention of corrosion is critical.
