Abstract
This paper contains the results of studies of the structure and composition of the surface layer of the tungsten coating of a rubber substrate. The rubber substrate is prepared on the basis two rubbers: polychloroprene rubber Denka RS‑40A (Bypass 611) with a mass fraction of 0.70; the rest-BNKS‑28 AMN. The deposition of tungsten on the substrate surface was carried out by magnetron sputtering on the installation «ADVAVAC VSM‑200». Microscopic studies of the surface layer of the samples, decoding of X‑ray images and elemental chemical analysis allowed us to determine the structure and phase composition of the surface layer depending on the time of sputtering of tungsten. It is shown that the surface layer of elastomers has a granular structure, which includes cluster formations of tungsten in the atomic state in the form of a β-modification of tungsten (W5) and individual inclusions of atomic elements that are part of the rubber substrate
