Abstract Scope One of the challenges in transportation vehicles such as aerospace, automotive, and rail cars is the greenhouse gas (GHG) emission associated with high fuel consumption. Structural lightweighting aims to tackle this problem by careful design and selection of materials at the component conceptual design stage. Once adopted, their manufacturing requires nanoscale material deposit and built of the component so to develop the competitive mechanical and tribological properties concurrently. This research is focused on the development of nanostructured surface protective coatings and 3D-freeform components on the sole idea of ceramic-metallic (cermet) composite materials. This paper presents the design of a novel cermet Ni-Zn-Al2O3 feedstock particle in high-energy mechanical alloying (HE-MA) process, followed by their deposition in a high-pressure cold spray (HPCS) additive manufacturing process. Results from investigating the feedstock deposition efficiency (DE) and bonding mechanisms will be presented on the merit of both feedstock and spray process detailed parametric study.
