Bu çalışmada, havacılık sektöründe yaygın olarak kullanılan AA6061, Ti-6Al-4V alaşımları ile SS304 paslanmaz çeliğinin yüksek hızlardaki erozyon davranışları deneysel olarak incelenmiştir. Erozyon deneylerinin bir kısmı 90° sabit çarpma açısı için 100, 127, 170, 210, 250 m/s çarpma hızlarında gerçekleştirilmişken diğer kısmı 100 m/s sabit çarpma hızı için farklı çarpma açılarında (20, 30, 45, 60, 90°) gerçekleştirilmiştir. Deneyler sonucunda numunelerdeki kütlesel erozyon oranları; zamana, hıza ve açıya göre elde edilmiştir. İlave olarak malzemelerdeki hacimsel erozyon oranları hesaplanmış ve malzemelerde oluşan krater derinlikleri ölçülmüştür. Çalışmalar neticesinde en iyi erozyon performansı kütlesel kayıplar bakımından AA6061 alaşımında ve en kötü erozyon performansı SS304 paslanmaz çeliğinde görülmüştür. Hacimsel erozyon performansı ise en kötü AA6061 alaşımında belirlenmiş ve bu sonuç optik profilometre cihazı ile yapılan ölçümlerde de desteklenmiştir.
In this study, AA6061, which is widely used in the aviation industry, has experimentally studied the high-speed erosion behaviors of Ti-6Al-4V alloys and SS304 stainless steel. Some of the erosion trials were performed at 100 m/s, 127, 170, 210, 250 m/s for a fixed collision angle of 90°, while the rest were performed at different collision angles for a fixed collision rate of 100 m/s (20, 30, 45, 60, 90°). The mass erosion rates in the samples were obtained according to time, speed and angle. Furthermore, the volume erosion rates in the materials are calculated and the crater depths formed in the materials are measured. The best erosion performance was found in AA6061 alloy in terms of mass loss and the worst erosion performance was found in SS304 stainless steel. The volume erosion performance was determined in the worst AA6061 alloy and this result was supported in measurements by the optical profilometer.
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.
