SAF MAGNEZYUMUN BİYOBOZUNUR MALZEME OLARAK KULLANILMA POTANSİYELİ

Abstract

Uzun süreli tedavi gerektirmeyen kemik travmalarında kullanılacak vida ve diğer bağlantı elemanlarının biyobozunur özelliğe sahip magnezyum alaşımlardan yapılması, özellikle büyüme çağındaki çocuklarda uygulanan, metalik implantların zamanla neden olduğu olumsuz etkileri ortadan kaldırmaktadır. Bu çalışmanın amacı; saf magnezyumun yapay vücut sıvısı (SBF) içerisindeki korozyon mekanizmasını 30 saat süren açık devre potansiyeli ölçümleri (OCP) ve bu esnada yapılan in-situ pH ölçümleriyle araştırmak ve iki yöntem arasındaki korelasyonu ortaya koymaktır. Elde edilen veriler çalışma elektrotunun yüzeyinde de zamanla oluşan Mg(OH)₂ tabakasının korozyon hızını etkilediğini göstermektedir.
