| Abstract Scope |
During cold spray, powder particles undergo severe plastic deformation upon impact with the substrate. This results in particle flattening, oxide breakage, and metallurgical bond formation at particle-particle and substrate-particle interfaces. At smaller length scales, heterogeneity of the bond coating can create property differences, which are yet to be explored. Thus, a comprehensive understanding of local interfacial bond strength at this heavily deformed interface would assist in designing optimal cold spray processes. In this study, we investigated the microstructure and mechanical properties of Al6061 cold sprayed coating on AZ91 magnesium substrates via correlative microscopy and in situ micro-tensile testing. Micro-tensile dogbones were fabricated using Plasma Focused Ion Beam (PFIB) and tested in situ to study the strength and deformation behavior of the interfaces. The bond characteristics at the interface are explored further via transmission electron microscopy (TEM). |
