Effects of Exposure to High-Velocity Streams of Microparticles

Abstract

Here in detail are presented the original, previously undisclosed results of the theoretical and experimental researches of the effects influence of the high-velocity flows of microparticles on the various kinds of obstacles (metallic and multilayer). A high-velocity impact of a microparticle on the surface of an obstacle primarily results in formation of a classic crater with the molten edges with the subsequent advancing into the obstacle, manifested in the instant development of the plasma processes. We will experimentally prove here the fact that development of these plasma processes is coexistent with formation of the pulse electromagnetic and ionizing irradiations. An impact of a high-energy microparticle also causes the surface and volumetric shock waves, which alongside static charges are instrumental in development of the electric breakdown of the dielectric and semiconductor materials. Here are also perused the influence peculiarities of these particles on the mechanical and electro-physical properties of multilayer materials and metals, peculiarities of the mathematical simulation of encounter of the high-velocity flows of microparticles with the space vehicles (SVs), as well as influence of the effect of the “super-deep” penetration (SDP) of microparticles on reliability of the radio-electronic devices of the spacecraft.
