Abstract
Biodegradable materials are considered to be the third generation of biomaterials. The aim of these biodegradable alloys is to provide healing and tissue regeneration of the bone. In recent years new types of BM, such as Mg-Si-Ca based alloys were developed and are considered promising candidates for implant materials during a limited time. The effect of Si and Ca addition on pure magnesium alloy has been investigated. The results showed the formation of an intermetallic compound Mg2Si. Morphology of this compound changed to polyhedral shape with increasing Si addition over 3wt%. The purpose of this paper is to investigate morphological and XRD aspects of casted pure Mg and Mg-XSi-YCa (X – 1.5wt%, 5wt%, 10wt% / Y-0.5wt%, 1wt%, 2wt%) by using optical microscopy, scanning electron microscopy and X-ray diffraction.
