Synthesis of Mg6Zn-xHAp Biocomposites Using Arc Plasma Sintering

Abstract

Development of magnesium-based biomaterials as biodegradable bone implants has been doing until now. One of the factors considered and developed is a method used in the synthesis process material. In this study, the synthesis process was done using Arc Plasma Sintering technology (APS). The APS was operated at a voltage of 12 Volts and a current of 1 ampere for 30 seconds. Biocomposites were characterized using XRD, SEM and Potensiostat. The XRD results showed that the crystal peaks in both biocomposites was shifted towards the right (larger tetha). This identified that the biocomposite had a smaller distance between the crystal planes after the sintering process. The SEM/EDS results showed that on Biokomposit Mg6Zn-5% HAp green, there was only Mg element, while on Mg6Zn-7% HAp green besides element Mg, there was also element of Zn and HAp. The corrosion test results revealed that the Mg6Zn-xHAp corrosion rate was higher when the composition of HAp in the material was greater.
