| Abstract Scope |
Supersonic impact of metallic microparticles onto metallic substrates induces far-from-equilibrium conditions at the contact interface, resulting in extreme plastic deformation and adiabatic heating that facilitate metallurgical bonding. In addition, more complex interfacial activities such as chemical mixing might take place when the particle and substrate have different chemical compositions. Here we study this phenomenon using single metallic microparticles bonded to substrates at supersonic velocities. Nanometer-scale structural and chemical interface characterizations were conducted to reveal the extent and nature of chemical mixing. In parallel, we performed in-situ micromechanical testing to directly measure interfacial strength and to understand the influence of interfacial mixing on bonding behavior. We discuss how chemical mixing proceeds under extreme impact conditions and how it can be harnessed to tailor interfacial properties. |
