High-performance martensitic stainless steel nanocomposite powder for direct energy deposition prepared by ball milling

Phase textures of metal–oxide nanocomposites self-orchestrated by atomic diffusions through precursor alloys

“…[1][2][3] MONs are usually materialized by assembling nano-scale building blocks of metal and oxides through bottom-up approaches including mechanical mixing, sol-gel processes, or coprecipitation methods. [4][5][6][7][8][9][10] Indeed, nano-scale particles of nickel (Ni) and yttria-stabilized zirconia (YSZ) materials are mixed with high-speed ball mills, pelletized, or spread over electrolyte membranes, and finally calcined at high temperatures to yield anodes for solid-oxide fuel cells (SOFCs). 11 The MON materials obtained in such bottom-up approaches, however, often suffer from poor transport performances that lead to increased power loss of the fuel cells and/or batteries.…”
