Assessment of the Erosive Wear Kinetics of Epoxy Coatings Modified with Nanofillers

Abstract

The paper presents results of investigation on the erosive wear kinetics of epoxy coatings modified with alumina or silica nanoparticles. Natural weathering caused a decrease of their erosive wear resistance. After a 3-year natural weathering, highest erosive wear resistance showed the epoxy coating modified with alumina nanoparticles.

Destruction of Epoxy Coatings under the Influence of Sodium Chloride Water Solutions

“…The degree of the porosity of polymer coatings determines their barrier properties in relation to the substrate [8,9,10]. The sizes and shapes of coating cracks formed under the influence of the actions of aggressive media depend on the kind and concentration of the medium [2,11]. Coating tightness and resistance to cracking may be increased by introducing (micro-and nano-) fillers with diverse sizes to their structure [12,13,14,15,16,17].…”
