金屬的電化學(xué)腐蝕 與防護(hù) 姓名: 學(xué)號(hào): 摘 要 : 腐蝕現(xiàn)象都是由于金屬與一種電解質(zhì)(水溶液或熔鹽)接觸,因此有可能在金屬/電解質(zhì)界面發(fā)生陽極溶解過程(氧化)。這時(shí)如果界面上有相應(yīng)的陰極還原過程配合,則電解質(zhì)起離子導(dǎo)體的作用,金屬本身則為電子導(dǎo)體,因此就構(gòu)成了一種自發(fā)電池,使金屬的陽極溶解持續(xù)進(jìn)行,產(chǎn)生腐蝕現(xiàn)象。 關(guān)鍵詞 : 電化學(xué)腐蝕原理 局部腐蝕 防護(hù)與應(yīng)用 Summary: Decay phenomena to all contact a kind of electrolyte(aqueous solution or Rong salt) because of metal, therefore probably take place in metal/electrolyte interface anode deliquescence process.(oxidize)At this time if there is homologous cathode on the interface restoring a process match, the electrolyte then contains the function of ion conductor, metal then is electronics conductor, therefore constituted a kind of selfmoving battery, make the metal anode deliquescence keeps on carrying on, the creation decays a phenomenon. Keyword:Give or get an electric shock chemistry corrosion principle the crystal decay the even corrosion decays protection and application to plate 1 F in response to the dint anode protection 引言 : 。 現(xiàn)代生活中,各行各業(yè)最離不開的就是工程材料,金 屬單質(zhì)及其合金是應(yīng)用最為廣泛和最重要的工程材料。但是,現(xiàn)代金屬及其合金材料的發(fā)展面臨的最大問題就是腐蝕,我國每年因
