IPA: /ˈæn.ti.rʌst/
KK: /ˈæntiˌrʌst/
A term used to describe materials or coatings that prevent rust from forming on metal surfaces.
The car was treated with an antirust coating to protect it from corrosion.
Antirust is formed from "anti-" (meaning against) and "rust" (from Old English "rust", meaning the reddish-brown oxide that forms on iron). The word "antirust" refers to a substance or treatment that works against rust formation.
Think of 'anti-' meaning against, and 'rust' referring to the oxide on metal. This helps you remember that antirust is something that prevents rust.
