Özet:

 Zn alloys have recently attracted attention in the search for biodegradable materials due to their high biocompatibility, moderate compared to biodegradable Mg and Fe degradation rate, and high strength. In particular, the mechanical and corrosion properties of Zn-based alloys are investigated by alloying with different elements. In this study, the Zn-1 Mg alloys were produced using three different casting methods: gravity casting, gravity casting under a magnetic field, and high-pressure casting HPDC. Their microstructure, mechanical, and corrosion properties were compared. It was determined that the Zn dendritic matrix phase and Mg2Zn11 eutectic structure were formed in all three casting methods. It has been observed that applying a magnetic field at the time of solidification thins the dendritic and eutectic structures. It has been observed that applying a magnetic field during solidification in gravity casting improves the mechanical and corrosion properties of the Zn-Mg alloy. While the highest Vickers hardness value was obtained by the high pressure die casting method, the lowest corrosion rate was obtained in the gravity casting sample performed under a magnetic field.

 Zn alaşımları sahip oldukları yüksek biyouyumluluk, nispeten yavaş biyobozunur Mg ve Feye göre bozunma hızı ve yüksek mukavemetleri nedeniyle son zamanlarda biyobozunur malzeme arayışında dikkat çekmeye başlamıştır. Özellikle farklı elementler ile alaşımlama yapılarak Zn esaslı alaşımların mekanik ve korozyon özellikleri incelenmektedir. Bu çalışmada Zn-1 Mg alaşımları; gravite yerçekimi döküm, manyetik alan altında gravite döküm ve yüksek basınçlı döküm HPDC yöntemi olmak üzere üç farklı döküm yöntemiyle üretilerek mikroyapı, mekanik ve korozyon özellikleri karşılaştırılmıştır. Her üç döküm yönteminde de Zn dendritik matris fazının ve Mg2Zn11 ötektik yapının oluştuğu tespit edilmiştir. Katılaşma anında manyetik alan uygulanmasının dendritik ve ötektik yapıyı incelttiği ettiği görülmüştür. Gravite dökümde katılaşma anında manyetik alan uygulanmasının Zn-Mg alaşımının mekanik ve korozyon özelliklerini geliştirdiği görülmüştür. En yüksek Vickers sertlik değeri yüksek basınçlı döküm yöntemi ile elde edilirken, en düşük korozyon hızı manyetik alan altında gerçekleştirilen gravite döküm numunesinde elde edilmiştir.
