一、概况金属与环境介质的化学或电化学作用变为金属的腐蚀,在大多数情况下,腐蚀是破坏性的,这种破坏性腐蚀遍及于各种使用金属的地方、从日常生活,仓库储存到交通、运输、通讯、建筑、机械、化工、冶金、国防等等部门都有形形色色的腐蚀问题,而在工业生产中腐蚀问题尤为普遍和严重。金属腐蚀在经济上造成的损失一般可分为直接损失和间接损失两大类,直接损失包括金属材料的损耗(据估计:冶炼出来的金属有1/10是腐蚀掉而无法回收的)。将金属
First, an overview of the metal and the environment of the chemical or electrochemical role of metal corrosion, in most cases, the corrosion is destructive, this destructive corrosion throughout the use of various metals from the daily life, warehouse There are all kinds of corrosion problems stored in transportation, transportation, communications, construction, machinery, chemical industry, metallurgy, national defense and so on. The problems of corrosion in industrial production are especially common and serious. Economic losses caused by metal corrosion can generally be divided into direct and indirect losses of two categories, direct losses include the loss of metal materials (an estimated 1/10 of the smelted metal corrosion and can not be recovered).
