The article deals with the issues of impact interaction of particles with layers of dispersed material of different thickness. The influence of the interaction velocity and the thickness of the substrate on the appearance and structure of the collision result is investigated. It is established that at low speeds there is a crater formation while the particle is on the substrate surface. With the growth of the interaction rate, the formation of a crown is observed, and particles penetrate into the substrate material. Experimentally determined the values of the velocity and thickness of the substrate, corresponding to the beginning of the formation of the crown.
