In the study, surface modification of 3005 aluminum alloy was carried out (different coating time and graphene ratios) with micro arc oxidation (MAO) technology. Surface characterization, phase analysis and erosion corrosion test of the coated samples were performed. After the process, it was observed that the alloy was coated successfully with MAO method, a denser coating layer was obtained with the addition of graphene and the pores on the surface were reduced. After MAO coating, it was detected a significant increase in erosion-corrosion resistance. It was determined that there was a 17.4% improvement in corrosion resistance with increasing graphene content.

Grafen Katkısının Mikro Ark Oksidasyon ile Kaplanmış 3005 Alaşımının Erozyon Korozyon Davranışı Üzerine Etkisi

Öz

Çalışmada 3005 alüminyum alaşımı, mikro ark oksidasyon (MAO) teknolojisi ile farklı işlem sürelerinde ve farklı oranlarda grafen ilavesi ile yüzey modifikasyonu gerçekleştirilmiştir. Kaplanan numunelerin yüzey karakterizasyonu, faz analizi ve erozyon korozyonu testi gerçekleştirilmiştir. İşlem sonrası alaşımın MAO yöntemi ile başarılı bir şekilde kaplandığı, grafen ilavesi ile daha yoğun bir kaplama tabakası elde edildiği ve yüzeydeki porların azaldığı gözlemlenmiştir. MAO sonrası numunelerde erozyon-korozyon dayanımında belirgin bir artış tespit edilmiştir. Artan grafen oranı ile erozyon korozyonu dayanımının iyileşme gösterdiği raporlanmış ve işlemsiz numuneye göre korozyon dayanımında 17,4% oranında iyileşme olduğu tespit edilmiştir.
