| Abstract: | Results of an experimental study of the high-rate (400–1200 m/sec) interaction of spherical aluminum particles with a surface
are given. Particle deformation was studied by means of a microscope. The mean values of the degree of particle strain were
determined by statistical processing for specimens with different hardness (hardened and unhardened steel and copper) and
produced in different spraying regimes (the pressure and temperature of a gas in a plenum chamber and a working gas). A relation
between the degree of particle strain and the impact velocity was obtained by using the design particle velocities for the
corresponding parameters.
