The results indicate that particle flattening ratio increases with the increase of gas temperature, but the increment rate decreases at higher gas temperature. Moreover, the bonding ratio increases due to the increment of material jet area at the interface. It is also found that a typical Ni particle impacted on the substrate consists of shear instability thin layer, severe plastic deformation region, and low plastic deformation region. The quality of the particle/substrate bonding is mainly governed by the shear instability thin layer, while the shape of the deposited particle is mainly governed by the plastic deformation regions. It is confirmed that the successful bonding between Ni particle and Cu alloy substrate can be attributed to the adiabatic shear instability mechanism.
