Alternate Immersion Method and Its Application of Studying on the Weathering Steel
-
摘要: 利用集成電路控制微電機實現了試樣在指定時間里的干濕周浸。敘述了周浸儀的線路設計,并用它測定了稀土含量對09CuPTiRE鋼耐大氣腐蝕性能的影響。發現當稀土含量達0.012%時,稀土能明顯地改善鋼的耐大氣腐蝕性能。Abstract: The alternate immersion following a prescribed cycle of samples was carried out by means of a micromotor controlled by integrated circuit. The design of this instrument was described and the effect of rare earths on the resistance to atmospheric corrosion of steel 09CuPTiRE was checked. It was shown that the rare earths in steel effectively enhance the resistanc to atmospheric corrosion when it's content in steel is above around 0.012%.
