| Abstract Scope |
Cold spray (CS) is a solid-state deposition method that involves accelerating particles below their melting point to adhere to a substrate, resulting in the formation of coatings or parts with promising applications. Therefore, it is crucial to understand the bonding types and impact modes of particles during CS. The bonding types, namely mechanical and metallurgical, are significantly influenced by the mechanical properties of both the particles and the substrates. In this work, mechanically alloyed AlCoCrFeNi high-entropy alloy feedstock particles are deposited onto a steel substrate employing the CS technique. The investigation revealed the impact of the propelling gas type (i.e., helium and nitrogen) and the hardness of the particles/substrate on the bonding types. Furthermore, a theoretical framework based on material properties is employed to predict the dominant impact modes, such as co-deformation, splatting, and penetration. These predictions are then compared to the experimentally observed impact scenarios of AlCoCrFeNi during CS. |
