A Dense Cr2O3/Al2O3 Composite Ceramic Coating Prepared by Electrodeposition and Sealing with Al2O3
Source abstract
Abstract
A dense Cr2O3/Al2O3 composite coating was fabricated on 321L stainless steel by electrodepositing an Al2O3 layer on a Cr2O3 coating. The composition, structure, and properties of the obtained ceramic coating were investigated. The results showed that Al2O3 fully infiltrated the Cr2O3 coating and significantly improved the compactness of the ceramic coating by filling in the pores and cracks between the Cr2O3 grains. The composite ceramic coating was heat-treated at 750 °C and exhibited a high microhardness of 219.4 HV500g, a bonding strength of 46.5 MPa, and excellent anti-corrosion and deuterium permeation suppression properties.
