【 摘 要 】

The article is devoted to the investigation of radiation-absorbing properties of the coatings formed on aluminum and titanium surfaces. Microarc oxidation in aqueous solutions was considered as a method of the coating formation. It was shown that the coatings obtained in iron-containing solutions were homogeneous, porous and had high absorption factor of electromagnetic radiation within the terahertz range (up to 70 %), which made this material extremely promising in terms of intensive development of terahertz technologies as well as stealth technologies. Investigations of elemental composition of the coatings were carried out by the X-ray fluorescent method, and the morphology of the surface was represented by the results of raster scanning electron microscopy. Absorption factors were measured using a TDS-21 terahertz spectrometer by KDP OJSC.
