Abstract:
Currently, various methods are used to study the processes
occurring on the surface of solids, in particular metals, and in areas close to the
surface. In the field of physics, one such method is to grow a film or coating of
another metallic material by simultaneously bombarding the surface of a metallic
material with gas ions. In films or coatings grown by this method, as well as in
the near-surface areas and the base material, the interaction of gas ions, atoms of
the film-base material occurs and a carbide system is formed. This suggests that
the formation of new phases and chemical compounds occurs in the metal-film-
base system. It differs in system parameters, film parameters or base material. The
study of changes occurring in the metal film-base system, along with the methods of
spectrometry and spectroscopy, is carried out by the method of thermally stimulated
desorption (thermodesorption), i.e. thermal heating of the metal film-base system to
obtain decomposition spectra from them depending on the heating temperature of
impurities. In this paper, the processes of the release of impurities from films and
coatings of silvery material grown on tantalum, molybdenum and tungsten bases as
a result of thermal heating bombarded with argon gas ions are studied.
