Abstract
A 3D-printed porous 410 L steel support with a novel ceramic multi-coating is fabricated to improve the oxidation resistance of porous metal components for extreme conditions. Simplified support´s morphology with straight channels fabricated by laser powder bed fusion enhances the applicability of wet-chemical coating methods. A multi-coating method combining electrophoretic deposition and infiltration improves the ceramic/steel interface. Ceria-based coatings with catalytic activity towards H2O and O2 provide both physical and dynamic chemical protection mechanisms. Excellent electro-chemo-mechanical stability and superior corrosion resistance (0.26×10-15 g2 cm4 s-1) are shown at 750 °C in air-3% H2O for 122h.
