Ceramic oxide coated az31 mg alloy For biomedical applications

Abstract

Biomaterials have benefited millions of people enhance their newlinequality of life in essentially every part of the world. Biomaterials are defined newlineas and#8213;a non-drug substance having a combination of natural or synthetic origin, newlinethat can be in contact with living body tissue and body fluid without causing newlineany adverse effectand#8214;. They play a significant role in restoring function and newlineaiding healing in individuals who have suffered as a result of infection or newlinedamage. Biomaterials were employed by Egyptian and Mayan civilizations newlinefor a multitude of ancient reasons. Nowadays, metallic implants are used as a newlinebiomaterial for orthopaedic applications due to the chemical, physical and newlinebiological properties that restore bone function. In general, metallic materials newlineare typically used for load-bearing applications and should have fatigue newlinestrength to resist the challenges of the day-to-day. The metallic material with newlinegood biocompatibility and mechanical properties are cobalt-chromium alloys, newline316 L Stainless steel and Titanium and its alloy, employed for healing the bonerelated newlineinjuries or defects for long-term and short-term application for newlinepractical uses. These metallic implants are not biodegradable and it requires newlinerevision surgery to remove the implant in our body and also mismatching the newlinemechanical properties of the natural bone. Hence employing them for shortterm newlineimplant application damages the healing bone. newlineBased to the literature report, Mg is biodegradable implant material newlineand fulfils the mechanical requirements with closer density (1.74g/cm2) and newlinesimilar Young s modulus (35-40 GPa) to that of the natural bone. It is the newlinefourth most essential element present in our body. It has newlineco-enzymatic activity in the synthesis of protein, plasma membrane and newlinecellular activities. Moreover, the excess of Mg that comes out of the implant newlinematerial can be removed by the urine. newline
