METALİK MALZEMELERİN YÜKSEK HIZLARDAKİ EROZYON DAVRANIŞININ DENEYSEL İNCELENMESİ

In this study, the erosion behaviors of AA6061, Ti-6Al-4V alloys and SS304 stainless steel, which are used commonly in the aviation industry, have been experimentally investigated at high speeds. A part of the erosion experiments were carried out at impact velocities of 100, 127, 170, 210, 250 m/s at a constant impact angle of 90°, the others carried out at different impact angles (20, 30, 45, 60, 90°) at a constant velocity of 100 m/s. As a result of the experiments, the mass erosion rates in the samples were measured and obtained the changes to time, velocity and angle. Also, the volumetric erosion rates in materials were calculated and the crater depths in the materials were measured. As a result of studies, the best erosion performance was obtained at AA6061 alloy and the worst at SS304 stainless steel. The worst volumetric erosion performance was obtained at at AA6061 alloy and that supported in the measurements with optical profilometer.
