Abstract
Glassy coatings have been shown to give very good corrosion protection to the steel substrate. Moreover they can also be utilised as a solar energy absorber. Introducing metallic particles into the glassy matrix can lead to coatings with improved mechanical strength and much higher thermal conductance of a resulting composite. Establishing of optimal conditions for synthesis of such coatings was the main goal of this work. The microstructure of the coatings was studied by SEM and optical microscopy while UV–VIS spectroscopy was used to estimate their optical properties.
