Abstract

The paper presents results of investigation on the erosive wear kinetics of epoxy-polyurethane coatings modified with alumina or silica nanoparticles, aged climatically for three years. Destruction of coating surface layers due to natural weathering caused a decrease of their erosive wear resistance. Modification of the composition of polyurethane (surface) layer with nanofiller caused the remarkable increase of erosion resistance. Epoxy-polyurethane coatings with nanosilica modified surface layer, showed the highest erosive wear resistance of all investigated coatings.
