| Abstract Scope |
A fundamental understanding of bonding and microstructural evolution in single particle impacts is critical for informing the coating formation mechanisms in cold spray. While these simplified systems provide valuable insight, they do not fully capture the dynamics of the full deposition process. Our recent works take advantage of the Laser-Induced Particle Impact Testing (LIPIT) setup to produce controlled single microparticle impacts, combined with 3D tomographic observations of the microstructure and the bonding state at the impact site. We now extend our analysis to few-particle systems and full coatings to seek favorable bonding conditions at the particle-particle interfaces. Our results assess peening effects associated with repeated particle impacts and the effects of surface preparation on coating formation. Quantitative measurements of bonded area at the particle-substrate and particle-particle interfaces inform processing–structure relationships and enable the development of analytical models that integrate single-particle physics into a broader framework for cold spray process design. |
