Antistatic Composite Coаtings on the Basis of Powder Paints

For operating under outer space conditions besides providing originally specified protective function, coating should often ensure accomplishment of functional properties, for instance conductivity of electric current. The solution of this problem can be reached by adding powder fillers with specified functional properties into powder paint. The paper deals with development of technique for formation of protective conducting coatings by filling powder paints and treatment in planetary ball mill. For protection of magnesium alloy shells the technique is offered which combines formation of the oxidized sublayer, introduction of electroconductive filler, treatment of the powder mixture in the planetary ball mill and electrostatic deposition of sifted mixture of definite dispersion. This allows sinking of static electricity from cabinets of the equipment for the space-crafts applications in conditions of the outer space.
