Investigation of the space vehicles coatings features

Samples of micro-arc oxidation coatings (MAO) on aluminum foil for the protection of the elements of spacecrafts (5C) against the stationary plasma thrusters (5PT) were obtained. The optimal treatment regimens were revealed, the investigations of the structure and properties of the protective coatings applied by micro-arc oxidation were carried out along with the investigations of MAO coatings for the impact factors of storage and use, measurements of the thermo-radiation characteristics of the electric resistance and erosion resistance test. The description of the experimental plant for determination of the plasma effects on the erosion resistance of MAO coatings is presented. The studies showed that the properties of coatings obtained by MAO satisfy the requirements and can be used as protective coatings for spacecrafts.
