Nanostructured Diamond Particles in the Development of Protective Anticorrosion Epoxy Coatings
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°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.
期刊介绍：
Protection of Metals and Physical Chemistry of Surfaces is an international peer reviewed journal that publishes articles covering all aspects of the physical chemistry of materials and interfaces in various environments. The journal covers all related problems of modern physical chemistry and materials science, including: physicochemical processes at interfaces; adsorption phenomena; complexing from molecular and supramolecular structures at the interfaces to new substances, materials and coatings; nanoscale and nanostructured materials and coatings, composed and dispersed materials; physicochemical problems of corrosion, degradation and protection; investigation methods for surface and interface systems, processes, structures, materials and coatings. No principe restrictions exist related systems, types of processes, methods of control and study. The journal welcomes conceptual, theoretical, experimental, methodological, instrumental, environmental, and all other possible studies.
