Comparing Relative Bond Characteristics Between Spherical and Elongated Morphologies for Cold Spray Process Using SPH Simulation

Abstract Under cold spray conditions, the modified Johnson–Cook model was adopted to perform single and multiple particle simulation for spherical elongated aluminum alloy- Al-6061 feedstock particles. The splat formations were realistically presented; temperature evolution throughout deposition process stayed below melting point of Al-6061, particles exhibited restitution impact velocities lower than 200 m/s. Feedstock with morphology experienced a elastic strain energy level after impact, which implied relative bond strength higher displacement curves in simulations both morphologies suggested greater shock upon impact. achieved by even though showed individually embedded substrate.
