Adiabatic shear instability based mechanism for particles/substrate bonding in the cold-gas dynamic-spray process (2004, background): “The remaining details of the finite element analysis carried out in the present work such as, optimization of the mesh size and its effect on convergence can be found in [9].”
Review of Relationship Between Particle Deformation, Coating Microstructure, and Properties in High-Pressure Cold Spray (2017, background): “There have been experimental [11, 12, 113, 221, 243-248] and numerical [8, 12, 213] studies of residual stress, which confirm this view.”
Analysis of the impact velocity of powder particles in the cold-gas dynamic-spray process (2004, background): “sufficient kinetic energy must be available to plastically deform the solid material and/or disrupt the surface film [3]; and (c) the particle kinetic energy at impact is typically significantly lower than the energy required to melt the particle suggesting that the deposition mechanism is primarily”
