Microstrains and topography of silver coatings made under ground-based conditions and in the outer space are compared. The coatings were made wiht the use of a hand-device constructed at the E. O. Paton Electric Welding Institute, Academy of Sciences of Ukraine. First-kind strains arising in silver coatings 350-500 nm thich on the D16 alloy base are -ЗО++90 МРа when the coatings are made under ground-based conditions. Similar coantings 600-800 nm thich made in the outer space have virtually no first-kind strains. We believe that the silver coatings made in orbiting laboratories will have longer operating time than the coatings made on the Earth.
