Abstract
To increase the service life of expensive space vehicles it is worthy while to pay attention to testing the equipment and technology for deposition of coatings under the conditions of the object service. The application of the electron beam technology as most feasible under the space conditions is considered. The quality of coatings and methods of technology realization are evaluated.
Keywords: coatings, electron beam technology, degradation, near-earth orbit, versatile hardware, coating properties, repair-restoration operations
