TRIBOLOGY AND COSMIC TRANSPORT SYSTEMS
A new stage in the development of cosmonautics requires the development of promising structural and lubricating materials that will ensure the operability both in the orbit of the earth and in outer space for a long period of operation of the products. Their development requires knowledge of the behavior of rubbing surfaces in a deep vacuum under the influence of infrared, ultraviolet and radiation radiation, the temperature drop in a wide range. All this highly raises the level of requirements for materials that can be used in the mechanisms of space vehicles.
