- 1腐蝕（鐵生鏽是其中一種；不等於地景的侵蝕 erosion）
Corrosion is the slow eating-away of metal by water, air, salt, or chemicals. Rust on iron is the picture most people know, but other metals corrode too, sometimes without that red-brown look. The word can mean the process, or the damaged stuff it leaves behind. It is the ordinary technical word in science and engineering; rust is the everyday word when the metal is iron. People also stretch it: they talk about the corrosion of trust or of public life, meaning something good is being slowly eaten away. That figurative use is still a bit formal. Though actually, rust is only one kind of corrosion, so in a lab report you should not swap the two without thinking. A nearby word, erosion, is wearing away of land or rock by wind and water, not chemical attack on metal.
From the word’s history
From Middle English corrosioun, from Old French corrosion or Late Latin corrōsiō 'gnawing away', from corrōdō.
源自拉丁文 corrōsiō「啃蝕」，來自 corrōdō「咬掉」。
組成From Middle English corrosioun, from Old French corrosion or Late Latin corrōsiō, “a gnawing away,” from Latin corrōdō, “gnaw away, corrode” (con- + rōdō, “gnaw”).
