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 122 h.
