Dynamic alloying in the mode of super-deep penetration (SDP) allows us to evaluate the effects that occur in the materials of the spacecraft when interacting with high-speed streams of cosmic dust. The results of the experiments are presented, confirming that dynamic alloying in the SDP mode creates anisotropy in a solid body and leads to a change in physical properties (electrical resistance, electron work function). The dynamic alloying increased the anisotropy of electrical resistance in technical aluminum 99.7% Al in 2.05 times (105%), led to a decrease of the electrical resistance in the longitudinal direction by 16% and increase in the transverse direction by 41%.
