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.
