Particle-target interactions of high-speed microparticle impact for resulting material modifications

Microscale particle-target interactions and the resulting modifications of the target material play a crucial role in the domains of industrial manufacturing and application process. As know that the processing and manufacturing, failure prevention, and even the spacecraft protection against hypervelocity micrometeorites and orbital microdebris. Based on such an interesting, noteworthy, and profoundly applied research, it quickly followed up and compiled a series of relevant studies for particle-target interactions of high-speed microparticle impact. Here, it discussed the gas-based, laser-based, and electrostatic-based of the high-speed microparticle impacts. Among these, laser-induced particle impacts stand out for their high throughput and the suitability for operation in small facilities or even on standard laboratory optical benches. Various behaviors have been observed with smaller projectiles, relatively high velocities, and extreme strain rates, which involved the description of launching system, dynamic capturing of high-speed videography, triggering and characterization of material response, and resulting material modification. Subsequently, it conducted a summary and future prospect of the focused topics. As expected that the particle-target interactions will become an effective tool for the study of microprocessing, multi-field coupling, material strengthening and modification, it will bridge multidisciplinary to understand the scientific phenomena involved in the impact process, also provides a novel strategy for the development of next-generation of ballistic impact testing.
