Nickel-based superalloy microlattices with periodic hollow struts were fabricated through a combination of two deposition-based methods - electrodeposition and pack cementation - via the following steps: (i) creating a template by self-propagating photopolymer waveguide prototyping, (ii) coating the template with nickel by electroplating, (iii) etching away the template, (iv) coating the Ni lattice with Cr, Al, and Ti by pack cementation, (v) diffusing the Cr, Al, and Ti rich coatings into the nickel to achieve a homogenized alloy and (vi) optionally, aging the alloy to create γ′-precipitates. The resulting nickel-based superalloy microlattices are 2–4 times stronger than pure Ni counterparts.
