Erosive wear of glass/epoxy composites coating filled with hexagonal boron nitride nanoparticles

Abstract

In this experimental study, organic and inorganic coatings are applied on glass/epoxy composite materials to acquire an advanced understanding of the erosive wear performance. After coating process, SiO2 erodent particles having an average impact velocity of 53 m/s and an average diameter of 250 µm were used to evaluate the erosion rates based on the weight loss in the test specimens. The impingement angles used in the tests were 30°, 60° and 90° and the erosion rateimpingement angle graphs were produced for each different test specimen. It was observed that the organic coatings developed erosion resistance at the end of the experiments. Weight loss measurements were compared by using alternative measurement method (surface mapping method) and erosion wear difference are discussed.
