Elektroforetik Yöntem Kullanılarak Mg-AZ 31 Alaşımının Go/Hap ile Kaplanması ve Sinterleme Sıcaklığının Yüzeyin Mikroyapısına Etkilerinin İncelenmesi
Mg ve alaşımları, sahip oldukları yüksek biyouyumluluk, kemiğe yakın elastisite modülü, kemik gelişimine yardımcı olması, gibi özellikleri nedeniyle biyomedikal alanda kullanım açısından ilgi çekmektedir. Ancak Mg elementinin korozyona olan yüksek afinitesi, vücut sıvısı içerisinde bu alaşımların uzun süreli kalıcı implant malzemesi olarak kullanımını sınırlandırmaktadır. Bu nedenle bu alaşımların biyomalzeme olarak uzun süreli kullanımlarını sağlayabilmek ve biyouyumluluk, biyoaktivite gibi özelliklerini geliştrimek için yüzeyleri kaplanmaktadır. Bu çalışmada Mg AZ31 alaşımı üzerine korozyon dayanımını ve biyoaktivitesini artırmak amaçlı elektroforetik yöntemle (Hidroksi apatit) HAp/ GO (Grafen oksit) kompoziti kaplanılmıştır. Kaplama işlemi sonrası 3 farklı sıcaklıkta sinterleme yapılarak sinterleme sıcaklığının film tabakasının mikroyapısı üzerindeki etkileri SEM, XRD ile incelenmiştir.
