This paper presents studies of the surface of titanium hydride fraction samples modified by applying to its surface an organic silicon oligomer and boric acid chemically from aqueous solutions, using methods of optical and scanning electron probe microscopy. To determine the surface topography of a solid, we used high-resolution scanning probe (atomic force) microscopy using the MFP-3D Stand Alone (MFP-3D-SA) AFM microscope. The presence of hydroxyl OH-groups on the surface of the initial titanium hydride was established by infrared spectroscopy methods. A significant increase in the intensity of absorption bands at 3480 and 3490 cm−1 (OH-groups) was recorded. Activation of the titanium hydride fraction surface with an organic silicon oligomer significantly increased the concentration of hydroxyl OH-groups on the surface of vacuum-dried titanium hydride fraction at 100 ℃. We observed a difference in the surface structure of the initial and activated titanium hydride due to the formation of polysiloxane shell, as well as a difference in the surface structure of titanium hydride fraction containing polysiloxane and borosilicate shells due to the vitrification of boron oxide at 300 ℃. The surface of a modified titanium hydride fraction containing a borosilicate shell showing a 4.2 µm atomic force scanning microscope probe stroke relative to the OX axis, small reductions of characteristic probe dips and elevations with height and depression differences to up 10 nm throughout the scanning area are visible.
