Corrosion behavior of magnesium alloys in simulated body fluid

Abstract

Metallic materials are essential element for biomaterials to assist with the repair or replacement of bone tissue. The biomaterials used currently, like stainless steels and titanium, can cause the release of chromium, iron, nickel or titanium needles of titanium oxide through corrosion or wear processes that lead to inflammatory cascades which reduce biocompatibility and cause tissue loss. Moreover, the elastic modulus mismatch with natural bone tissue cause the stress shielding effects that can lead to reduced stimulation of new bone growth and remodeling which decrease implant stability. The ceramic and plastic materials also are widely used biomaterials. However the mechanical properties like strength, stiffness and fragility are too weak for structure reconstruction and fixation application like screw or nail.
