Abstract

This study investigates the deposition of a CuZr metallic glass particle on amorphous/crystalline composites through molecular dynamics simulations. The research reveals that increasing impact velocities lead to greater plastic deformation and disintegration of the projectile, with noticeable differences in substrate response based on crystalline layer thickness. Thicker crystalline layers enhance the substrate's resistance to deformation, acting as effective barriers during impact. Additionally, the interactions between the amorphous matrix and crystalline phases are critical in determining mechanical behavior. These findings provide valuable insights into the performance of coatings, particularly for cold spray applications, highlighting the importance of optimizing layer properties to improve material durability.
