| Abstract Scope |
Metallurgical bonding and material buildup during cold spray occur by high-velocity impact of micrometer-sized metallic particles onto metallic substrates. While the conditions necessary for supersonic impact-induced bonding in metals are relatively well understood, the properties emerging at the bonded interfaces remain elusive due to the nanosecond time scale and the micrometer length scale of the impact-bonding process. In this study, we isolate individual interfaces by producing single particle impact-bonding events with precisely measured or controlled kinetic, thermal, and geometrical parameters using in-situ microparticle impact experiments. We then conduct site-specific micromechanical measurements to study the interfacial strength. Finally, we discuss the role of the spatial and temporal evolution of the contact pressure and the interfacial strain in governing the impact-induced strength. |
