Abstract It is shown that the introduction of fullerene-containing soot (FCS) into silicate-alkaline electrolyte for microarc oxidation (MAO) of aluminum has a significant effect on the structural-phase state of the coating and its optical properties. In all cases, when it comes to thickness, various composite coatings are formed, its colors change from light gray to black, which leads to the appearance of a high-temperature phase of aluminum oxide, as well as to reflection in the visible spectrum and in the IR range.
Keywords
