Corrode the grass rust, can deep clean the treasures [tre(r)z] exertion [gz:n], if good at using gold, but will bring more gold hygiene [haid:n]. 腐蚀的臭锈，能把深藏的宝物消耗干净，黄金如善于利用，却能把更多的黄金生。——莎士比亚《维纳斯与阿都尼》
Corrode的本义 [k'rud] v. 腐蚀；损伤 Rust [rst] has corroded the steel rails. 锈侵蚀了钢轨。图片来源：es.dreamstime.com Certain chemicals ['kemklz] will corrode if left on bare [ber] metal. 有些化学药品如果留在裸露的金属上会起腐蚀作用。
Hatred [hetrd] corroded his character [kærkt(r)]. 仇恨损伤了他的人格。The worst crisis has already started to corrode her hope for freedom. 严重的经济危机开始消蚀她对自由的希冀。
Corrode VS Erode corrode指的是化学性腐蚀，是通过化学反应达到的腐蚀，如铁的氧化造成的腐蚀。名词形式为 corrosion [k'rn]。Acid [æsd] causes metal to corrode. 酸会使金属腐蚀。Iron tools corrode easily. 铁制工具易受腐蚀。

Zinc [zŋk] is used to protect other metals from corrosion. 锌被用来保护其他金属不受腐蚀。erode [rd] 也有腐蚀，侵蚀的意思，但它指的是机械物理性腐蚀，如气候、水冲刷等。名词 erosion ['rn] 还可以表示水土流失。
The action of water and wind causes the erosion of rocks. 风和水的作用会引起对岩石的侵蚀。Rainfall is the key factor to soil [sl] erosion. 降雨是影响土壤侵蚀的关键因素。

These data could be used to study the material weight-loss models in erosion-corrosion process. 这些数据为研究腐蚀和磨损过程材料损失模型提供了研究基础。以下是开篇视频 Corrosion of Metals 中的一些核心内容，大家可以再巩固一下。
Corrosion is described as a formation of compounds on the surface of a metal when it is exposed to air and water or an electrolyte like salt water. 腐蚀是指当金属暴露在空气和水，或者电解质如盐水中，在其表面形成的化合物。
Typically once a metal corrodes it forms compounds known as oxides or hydrated oxides. 通常当金属开始腐蚀时，便会形成氧化物或氢氧化物。
The nail made of iron rusted is the only time you should use the term rusting. All other metals are considered as having been corroded when they react with water or oxygen in the air. 只有当铁钉长锈时，才会说“生锈”。
当金属和水或空气中的氧气发生反应时，通常被称作“腐蚀”。But why would the nail be more corroded than the aluminium toy, the copper pipe or the gold ring? Have you any ideas? 但为什么铁钉会比铝制玩具、铜管或者金戒指更容易腐蚀呢？你知道其中的原因吗？
The reason is the metals all have different reactivities. Iron corrodes faster because it is more reactive than the copper and the gold. 这是因为金属的活性各不相同。铁之所以腐蚀更快，是因为它的活性比铜和金更强。
