Bu çalışmada, AISI 1020 çelik ve Ti-6Al-4V titanyum alaşım malzemelerinin katı partikül (parçacık) erozyon davranışları deneysel ve sayısal olarak incelenmiştir. Deneyler ve sayısal simülasyonlar, farklı partikül çarpma hızları (100, 127, 170, 210, 250 m/s) ve açıları (20, 30, 45, 60, 90°) için gerçekleştirilmiştir. Bununla birlikte, aynı malzemelerin bir helikopter pali aşınma kalkanındaki erozyon performansları, 0° hücum açısı ve 230 m/s çarpma hızı şartlarında MIL-STD-3033 standartına göre yapılmışken sayısal erozyon analizleri Eulerian-Lagrangian yaklaşımlı ayrık faz metodu ve ampirik erozyon eşitliği kullanan ticari ANSYS_Fluent 15.0 paket programı ile gerçekleştirilmiştir. Çalışmadan elde edilen sonuçlara göre, sayısal sonuçlar deneysel veriyle iyi derecede uyumlu ve AISI 1020 çeliğinin kalkan yüzeyindeki erozyon performansı Ti-6Al-4V alaşım malzemesinden daha iyi elde edilmiştir.

In this paper, solid particle erosion behaviors of AISI 1020 steel and Ti-6Al-4V titanium alloy materials were experimentally and numerically investigated. Experiments and numerical simulations were carried out for the conditions of different particle impact velocities (100, 127, 170, 210, 250 m/s) and angles (20, 30, 45, 60, 90°). Moreover, erosion performances on the erosion shield of a helicopter rotor blade of aforementioned materials were numerically determined for the condition of angle of attack of 0⁰ and impact velocity of 230 m/s. Numerical erosion analyzes were performed with ANSYS_Fluent 15.0 package program using discrete phase method with Eulerian-Lagrangian approach and an empirical erosion equation while experimental erosion tests were conducted by MIL-STD-3033 standard. As a result, numerical results were in good agreement with the experimental data, and it was obtained that erosion performance on the shield surface of AISI 1020 steel material is better than Ti-6Al-4V titanium alloy material.
