Abstract Scope |
In the cold-spray method, a powdered feedstock is deposited onto a substrate through a pressurized nozzle at a supersonic velocity. During the process, significant microstructural and compositional variations occur, particularly at the interface, owing to small powder particle size and shallow surface penetration compared to particle size. As a result, the mechanical properties of cold-sprayed components generally differ from bulk material, and applications for cold-sprayed products are limited. This study aimed to characterize the microstructures of as-sprayed and post-processed cold-spray samples and quantify mechanical properties. The resultant information and literature data were used to identify microscopic phenomena that show relationships between local particle adhesion, material porosity, and bulk material properties. Experimental results garnered in this study will be incorporated into crystal plasticity modeling for relevant components. |
