Nuclear industries can benefit from materials that perform well mechanically and thermally in high temperature and corrosion environments. Functionally graded materials (FGM) are materials manufactured with complex spatial, structural, and chemical compositions, creating components predesigned with tailored microstructural and mechanical properties. Porosity-graded FGMs are designed to introduce pores into a component’s structure as a mechanism to increase bulk or surface material performance, such as stress accommodation and negative thermal conductivity. Additive manufacturing (AM) techniques such as laser engineered net shaping (LENS) and wire arc additive manufacturing (WAAM), excel in high energy density, point-to-point metal deposition, and present in conjunction with other combinatorial approaches, exciting methods to manufacture porous FGM components. Plasma jet printing is also examined as another means of fabrication method evaluations for smaller scale graded components. This study explores AM FGM process parameters, combinatorial fabrication methodologies and preliminary characterization results for components functionally graded in porosity levels.
