N2  - Protective coatings produced by using Physical VapourDeposition (PVD) method can increase the life time of the components.Therefore; in this study, ≈0.25 mm thickness ZrN coatings are applied on Glass FiberReinforced Epoxy (GF/EP) and Carbon Fiber Reinforced Epoxy (CF/EP) compositesby magnetron sputtering to gain an improved understanding of the erosionresistance. The impingement angles used in the tests were 30°, 60° and 90°, while the impact velocity was 53 m/s. Al2O3abrasive particles with an average diameter of 200 mm was used. Alltest specimens regardless of their various properties exhibit maximum erosionrates at 30° impingement angle and thus exhibiting similarbehavior as that observed for ductile materials. Optic microscopic views wereperformed on the surfaces in order to characterize the erosion mechanism. Theerodent particles of the both coating layer and composite matrix were found ofmain role in governing the wear progression. The measured erosion rates weresensitively correlated with the material removal process in order to explainthe changes within the coated interfaces.
