Özet

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 degrees, 45 degrees, 60 degrees, 75 degrees, 90 degrees) 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.
