Etymology: "Unrusted" is a plain formation: the prefix "un-", meaning "not" or "without", attached to "rusted", the past participle of "rust" used as an adjective. Together they describe something that has not gone rusty, or is free from rust. The prefix "un-" is native English and has been productive since Old English, so it can be added to many participles and adjectives on the fly. "Rusted" itself comes from the verb "rust", which descends from the Old English "rūst", a word for the reddish-brown oxide that forms on iron exposed to moisture and air. The pairing with "un-" is simply a descriptive negation, one a speaker can coin as needed rather than a term with its own separate history.
