MgAlSi Üçlü Alaşımının Üretimi ve in-vitro biyo Uyumluluk İncelemesi

Abstract

Bu çalışmada biyo uyumlu Mg metali ile birlikte Al ve Si elementlerini içeren bir alaşım üretilmiştir. Üretim işlemi indüksiyon ocağında ergiterek yapılmıştır. MgAlSi üçlü alaşımı üretim sonrasında 350C/12 saat homojenleştirme ısıl işlemine alınmıştır. Elde edilen numunelere mikro yapı incelemesi için taramalı elektron mikroskobu (SEM) kullanılmıştır. Biyo uyumluluk incelemeleri için daldırma korozyon, potansiyodinamik korozyon ve sitotoksisite (MTT) olmak üzere 3 farklı test ile uygulanmıştır. Korozyon testleri Hank’s solüsyonu içerisinde gerçekleştirilmiştir. pH dengesi ve % canlılık oranı analizleri ile temel biyouyumluluk şartlarını taşıdığı sonucuna varılmıştır. Böylece yapının biyo malzeme olarak kullanımı tartışılmıştır.

Production of MgAlSi Ternary Alloy and in-vitro bio Compatibility Investigation

Abstract

In this study, an alloy containing Al and Si elements together with biocompatible Mg metal was produced. The production process was made by melting in an induction furnace. MgAlSi ternary alloy was subjected to 350C/12h homogenization heat treatment after production. Scanning electron microscope (SEM) was used to examine the microstructure of the obtained samples. For biocompatibility studies, it was applied with three different tests: immersion corrosion, potentiodynamic corrosion and cytotoxicity (MTT). Corrosion tests were carried out in Hank's solution. It has been concluded that it meets the basic biocompatibility conditions with pH balance and % vitality analysis. Thus, the use of the structure as a biomaterial is discussed.
