A tendency towards an increase in the number of projects aimed at space flights of automatic scientific stations to the planets of the Solar system and to asteroids is indicated. The problem of prevention of mutual adhesion of metals (cold welding) by means of optimal selection of coatings for deployment units of delayed actuating is highlighted. A promising direction for preventing cold welding of contacting metal surfaces of spacecraft deployment units is indicated – the use of micro-arc oxidation technologies. The data on the device used in the simulation, as well as the experimental technique, are given. Based on the results of studying the profilograms of wear zones, the depths of wear of each MAO coating on the studied aluminum alloys were measured. Based on the processing of the data obtained, quadratic regression equations for each thickness of the studied MAO coating were derived. A conclusion about the influence of the hardness of the metal substrate on the resistance of the MAO coating to vibrating impact loading and fretting wear is made. The ways of increasing the resistance of the contacting surfaces of the spacecraft deployment units, taking into account the application of microarc oxidation technologies, are proposed.
