Protective coatings produced by using Physical Vapour
Deposition (PVD) method can increase the life time of the components.
Therefore; in this study, ≈0.25 mm thickness ZrN coatings are applied on Glass Fiber
Reinforced Epoxy (GF/EP) and Carbon Fiber Reinforced Epoxy (CF/EP) composites
by magnetron sputtering to gain an improved understanding of the erosion
resistance. The impingement angles used in the tests were 30°, 60° and 90°, while the impact velocity was 53 m/s. Al2O3
abrasive particles with an average diameter of 200 mm was used. All
test specimens regardless of their various properties exhibit maximum erosion
rates at 30° impingement angle and thus exhibiting similar
behavior as that observed for ductile materials. Optic microscopic views were
performed on the surfaces in order to characterize the erosion mechanism. The
erodent particles of the both coating layer and composite matrix were found of
main role in governing the wear progression. The measured erosion rates were
sensitively correlated with the material removal process in order to explain
the changes within the coated interfaces.
