Source abstract
Abstract
Abstract The present work deals with study of corrosion behavior of Magnesium based biodegradable alloy added with 1393 bioactive glass in simulated body fluid, which can be used as an orthopedic implant or bone fixation. Various efforts had been done for development of magnesium based alloy but the main problem observed was high corrosion rate. Our work consists of developing a Magnesium based alloy with addition of Zinc, Aluminum and Calcium along with 15% 1393 bio-active glass. The alloying elements have their own advantages associated with them. Further the alloy has been studied for the corrosion behavior after 1 days, 3days, 5 days, 7 days and 14 days. Samples have been tested for their corrosion behavior in simulated body fluid and their corrosion rate has been observed by weight loss method and electro potentio-dynamic tests. Atomic Absorption Spectrophotometry (AAS) of the samples has been done in order to get more precise results. Young's Modulus of the alloy has been found to be in the range of 33.80 GPa–46.72 GPa, which is near to the human bone. Also the surface morphology and phase analysis of the samples has been done by Scanning Electron Microscopy and X-Ray Diffraction Technique. Initial corrosion rate of the sample is fast but after 7 days the decrease in corrosion behavior has been observed. SEM images of the samples have confirmed the formation of hydroxyapatite layer and the X-Ray Diffraction of corrosion products have shown the formation of complexes of Magnesium on the surface.
