Effect of the Substrate Surface Activation on the Process of Cold Spray Coating Formation

A model that takes into account the influence of surface activation by particles of the sprayed material on Cold Spray process is proposed in the present paper. With the help of this model, particle adhesion to the surface is numerically calculated. Some typical dependences of the coated area on the number of impacts for different particle velocities and temperatures are obtained. These dependences are in satisfactory agreement with the results of experiments.
