| Abstract Scope |
Solid phase processes have garnered increasing attention in the domain of metal processing. They can not only bypass metallurgical constraints and challenges associated with melt-based processing approaches but also lead to enhanced mechanical properties compared to the melt-based counterparts. Cold spray is one of the emerging solid phase processes with applications in structural coatings, structural repair, and additive manufacturing. In cold spray supersonic impacts of power particles induce extreme conditions of strain rate, pressure, and shear at the contacting interfaces the result of which is solid-state bonding at micron scale. This talk will survey our work using an in-situ platform to study impact and bonding of individual powder particles and the associated phenomena in real time. We discuss new insights on impact-induced bonding mechanism, adiabatic plastic deformation, jetting, and microstructural evolution at the interfaces. We review in detail the conditions under which we observe solid-state bonding, impact-induced melting and erosion. |
