摘要：

In this work, nanostructured diamond particles are considered as fillers for epoxy coatings. Nanodiamonds and a diamond charge obtained as a result of detonation synthesis from a mixture of TNT and hexogen are characterized by IR spectroscopy, scanning electron microscopy, and thermal analysis. It has been shown that nanodiamonds are characterized by thermal stability up to 450 degrees C and increase the thermal stability of epoxy coatings. The influence of nanodiamonds and diamond charge, depending on their quantity and synthesis conditions, on the physical and mechanical properties (hardness, contact angle, adhesion, impact and bending strength) of epoxy coatings is studied. The results of a study of the anticorrosion resistance of epoxy coatings with 10 wt % nanodiamonds compared to polymethylphenylsiloxane resin coating using methods of potentiodynamic polarization, linear polarization resistance, and impedance measurements, supplemented by field tests in humid tropical climates are presented.
