Abstract (2. Language): 
In this study, solid particle erosion behaviors of AA-1070 and AA-6101 alloys used in high-voltage power transmission lines for energy transfer were investigated.During their service life materials used in power transmission lines are exposed to extreme atmospheric conditions.Meteorological events, such as sand storms, especially cause these materials to wear due to solid particle erosion. Material loss due to solid particle erosion and cross-sectional narrowing in wires lead to a reduction in their service life whichcauses large scale losses in power transfer lines.In this study solid particle erosion behaviors of AA-1070 and AA-6101 aluminum alloys used in power transfer lines were investigated at various impingement angles (30°, 45°, 60°, 75°, 90°) and compared.Surface morphology of eroded samples was examined by using scanning electron microscope (SEM) and energy-dispersive X-ray spectroscopy (EDS) and dominant erosion damage modes were determined.

Abstract (Original Language): 
Bu çalışmada yüksek gerilim hatlarında enerji iletimi için kullanılan AA-1070 ve AA-6101 alaşımlarının katı partikül erozyonu davranışları incelenmiştir. Servis ömürleri boyunca enerji nakil hatlarında kullanılan malzemeler zorlu atmosfer şartlarına maruz kalmaktadır. Özellikle kum fırtınası gibi meteorolojik olaylar bu malzemelerin katı partikül erozyonu ile aşınmalarına neden olmaktadır. Katı partikül erozyonu nedeniyle oluşan malzeme kaybı ve iletken kesitindeki daralmalar bu malzemelerin kullanım ömürlerinin kısalmasına ve bunun sonucunda enerji nakil hatlarında büyük enerji kayıplarına yol açmaktadır. Bu çalışmada enerji nakil hatlarında kullanılan AA-1070 ve AA-6101 alüminyum alaşımlarının farklı partikül çarpma açılarında (30°, 45°, 60°, 75°, 90°) katı partikül erozyonu davranışları incelenmiş ve karşılaştırılmıştır. Aşınan malzeme yüzeyleri taramalı elektron mikroskobu (SEM) görüntüleri ve enerji dağılımlı X-ışını analizleri (EDS) yardımıylaincelenmiş ve aşınmaya yol açan etkin aşınma mekanizmaları belirlenmiştir.
