Research Abstract

It is now widely known that a coating can be obtained simply by projecting powder particles onto a substrate at high velocity. The conditions to obtain a coating and what kinds of bonding are made between the particles and the substrate were studied by numerical simulation and experiments. It was found that the interface regions which underwent heavy shear deformation by the impact tend to form tight bonding. Also, the velocity and temperature of the particles at impact affect the density and internal crystal structures of the coating.
