Bu çalışmada, yüksek hızlı oksi-yakıt püskürtme (HVOF) tekniği ile Stellite-1 tozu ile kaplanan AZ91D magnezyum alaşımının aşınma davranışı araştırıldı. Deney numunelerinin aşınma kayıpları farklı yük ve kayma mesafeleri için laboratuvar deneyleri ile ölçüldü ve bu değerler yapay sinir ağları (YSA) modellemede veri seti olarak kullanıldı. Çalışmada kullanılan veri seti 108 adet aşınma kaybı verisinden oluşmaktadır. YSA modellemede giriş parametreleri olarak; numune çeşidi, ortalama sertlik (HV0.1), yüzey pürüzlülüğü (Ra=µm), normal kuvvet (N) ve kayma mesafesi (m) kullanıldı. Çıkış parametresi olarak ise aşınma kaybı (AK) miktarları (mg) kullanıldı. YSA ile aşınma kayıplarının tahmininde başarım oranı 0.9793’ dür.
