Abstract:
A technique for obtaining composite sol-gel coatings containing finely dispersed forms of carbon powders is
presented. Optimal compositions have been developed and modes of deposition and heat treatment of formed coatings on
aluminum substrates have been selected. The results of the study of thickness, adhesion to the substrate, hardness and resistance
to cyclic effects of temperature changes (from minus 20$^\circ$ C to plus 150$^\circ$ C) are presented. The influence of the concentration of
introduced carbon powders on the reflection coefficient of the formed sol-gel coatings has been established.
Keywords:
film-forming solution, sol-gel, heat treatment, coating thickness, adhesion, hardness, reflection coefficient.
