Corrosion behavior of the new wear resistant steels Ti60 and ANM450 applied for middle plates of scraper conveyor

Abstract

This paper looks into the microstructure and phase structure of the new wear-resistant steels Ti60 and ANM450 applied for middle plates of scraper conveyer.Their corrosion behaviors in deionized water, corrosion ion solution, scaling ion solution and simulated mine water were studied by weight loss method, electrochemical tests and XRD analysis.The results showed that the corrosion order was corrosion ion solution>simulated mine water>scaling ion solution>deionized water. The order of corrosion resistance was Ti60 > Hardox450 > ANM450.The corrosion products were Fe2O3、α -FeO(OH) and Fe (OH)3, which indicated that iron was dissolved during the corrosion process.
