Abstract
Microstrains and topography of silver coatings made under ground-based conditions and in the outer space are compared. The coatings were made with the use of a manual tool developed at the E.O. Paton Electric Welding Institute, Academy of Sciences of Ukraine. First-kind strains arising in silver coatings 350-500 nm thick on the D16 alloy base are -30-+90 MPa when the coatings are made under ground-based conditions. Similar coatings 600-800 nm thick 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.
Keywords: space, material evaporation, electron beam heating, microgravity, surface topography
