Abstract

The results of a study of the chemical structure changes and the nature of the chemical bonds of the epoxy-polysiloxane nanocomposite with enhanced adhesion to titanium alloys with the introduction of particles of a modifying additive and highly disperse antifriction filler, and also under the action of large shear stresses during the cold plastic deformation are presented. These studies were carried out by IR spectroscopy. It is shown that the chemical or physical destruction of polymer chains of the composite does not occur due to the action of plastic deformation. However, redistribution of hydrogen bonds in its structure and physical bonds with the filler is observed. The number of bonds that are responsible for adhesion to the titanium surface is increasing
