Development of (SS-HAP-Ag) hybrid composite material from naturally extracted hydroxyapatite for orthopedic implants

Abstract

In present times the HAP is of great interest among researchers because of its similar characteristics similar to human bone. The HAP can be synthesized in two ways, through chemical methods and through extraction from natural resources. The chemical route can be expensive and un-sustained for the environment while as the extraction method from natural resources can be key to make the whole process environmentally friendly. Even though HAP is similar to human bone it lacks the necessary mechanical properties which are essential for bio-implants. It is a wellknown fact that Stainless Steel (316L) is suitably bio-compatible, but it also lacks the necessary Anti-bacterial properties which can be improved by addition of an alternative candidate having anti-bacterial properties such as Silver (Ag). This study proposes development of a hybrid composite of (SS316L, HAP, Ag) through powder metallurgy route with improved properties.
