Properties of Iron Tailing Coatings on Stainless Steel Substrate

Abstract:

Article Preview

Flame sprayed iron tailings coatings on the boiler steels are characterized before and after melting. The attempt has been made to investigate the microstructure, erosion resistant, wear resistant of the coated and melted samples. The techniques used are SEM and XRD. The results show that: Good adhesion between the coating and the substrate is caused by the formation of Al2SiO3 and (Cr, Fe)2O3 at the interface of the coated specimen. The stainless steel substrate with ceramic coating has a higher erosiSubscript texton resistance than the uncoated specimen because the mixed powder changes to a glass-coating in the high temperature heat treatment, and a few mullite are formed. Mullite has the high hardness value that makes the hardness of the coating increased. The wear resistance of the coated samples is better than that of the uncoated samples because glass-coating is more smooth than the uncoated specimen and the mullite in the coating has the high hardness value that makes the hardness of the coating increased.
