摘要
Abstract
X80 pipeline steel with different content of Y were prepared,the corrosion morphology and electrochemical properties of the steel in simulated concrete environment were studied.The results show that with the increase of Y content,the average grain size of the steel gradually decreases.Y2O3 compounds form along grain boundaries in the steel with Y addition.The corrosion products of the steel mainly contain FeOOH,Fe3O4,Fe2O3,FeO,FeS and FeC12.The steel with 0.045％Y addition has the best resistant corrosion performance.关键词
