Anodik oksidasyonun 2017A alaşımının tribolojik davranışına etkisi

Öz

Anodik oksidasyon, alüminyum alaşımlarının aşınma direncini ve yüzey özelliklerini iyileştirmek için kullanılır. Bu çalışmada, model uçak motoru pistonu olarak kullanılan 2017A alüminyum alaşımının, aşınma özelliklerine iki farklı anodik oksidasyonun (sert eloksal ve fosforik kaplama) etkisi incelenmiştir. Anodik oksidasyonun etkisini belirlemek için numunelerin mikrosertlikleri, sürtünme katsayıları, aşınma dirençleri, titreşim ve aşınmış yüzey görüntüleri değerlendirilmiştir. Anodik oksidasyonun numunelerin sertliğini, sürtünme katsayısını ve aşınma direncini önemli ölçüde iyileştirdiği sonucuna varılmıştır.

Effect of Anodic Oxidation on Tribological Behavior of 2017A Alloy

Öz

Anodic oxidation is used to improve the wear resistance and surface properties of aluminum alloys. In this study, the effect of two different anodic oxidation (hard anodizing and phosphoric coating) on the wear properties of 2017A aluminum alloy used as a model aircraft engine piston was investigated. In order to determine the effect of anodic oxidation, microhardness, friction coefficient, wear resistance, vibration, and worn surface images of the samples were evaluated. It was concluded that anodic oxidation significantly improved the hardness, friction coefficient, and wear resistance of the samples.
