Biomolecular Template‐Induced Biomimetic Coating of Hydroxyapatite on an SS 316 L Substrate

Abstract

Bone, a natural composite, comprises non‐stoichiometric calcium hydroxyapatite (HAp) precipitated in a controlled reaction environment of a highly aligned, anisotropic organic template (type I collagen) that leads to its exotic tensile and compressive strength. It differs from stoichiometric hydroxyapatite in composition, crystallinity, and other physical and mechanical properties. In the present study, functionalized biomolecular template‐induced precipitation of HAp on an SS 316 L substrate following biomimetic route exhibits distinct alterations in crystal growth and geometry, which in turn indicates the potential of the process to develop a non‐stoichiometric HAp coating on metal implants.
