Turgenev, 95 Komsomolskaya st., Orel, 302026, Russian Federation Abstract It is possible that a situation may arise in which adhesion of structural elements during their operation or sticking of structural material parts to each other is not permissible. In practice, anti- adhesive coatings or insulating layers are widely used. Currently, a number of experimentally tested materials with anti-adhesive properties are known: talc, molybdenum disulfide, fluoroplastic, etc. At the same time, it should be noted that there are no criteria with the help of which one can theoretically predict the adhesive or anti-adhesive properties of certain pairs of materials. This paper proposes a basis for constructing such criteria. Linearly elastic materials are considered. Within the framework of the model under consideration, pair and triple potential interactions of particles of interacting materials at finite distances are taken into account.
