corrosiion
|
|
| Corrosion of iron is inhibited by coating it with numerous substances, such as paint, an aluminum powder gilt, tin, or organic tarry substances or by galvanizing iron with zinc. Alloying iron with metals such as nickel or chromium yields a less corrosive steel. "Cathodic protection" of iron for lessened corrosion is also practiced. For some pipelines and standpipes zinc or magnesium rods in the ground with a wire connecting them to an iron object have the following effect: with soil moisture acting as an electrolyte for a Fe — Zn couple the Fe is lessened in its tendency to become Fe2+. It acts as a cathode rather than an anode. |

| 抑制鐵的腐蝕是通過對它添加涂層物質,如涂料,一種鋁粉末的鍍金,鍍錫,或有機焦油狀物質,或對鐵進行電鍍鋅。利用鎳或鉻對鐵進行合金化處理能產(chǎn)生不銹鋼。為減少腐蝕,鐵的“陰極保護”法也被應用。對于一些埋在地下的鋅制管道和豎管或鎂棒,將它們利用導線與鐵相連具有以下的效果:通過土壤的水分形成Fe — Zn的電解液,F(xiàn)e有轉化為Fe2 +的趨勢而減少。它是作為陰極,而不是陽極。 |
