Metallic orthopedic implants are typically made more biocompatible by incorporating a layer of hydroxy-apatite (HA) via thermal spray process. However, this being a line of sight process it has some limitations and issues associated with it. Recently, a new method to form HA coating has been developed which uses electrochemical bath with calcium and phosphate ions.
This paper will discuss the deposition of such coating and its characterization. It will present the results of surface morphology of the substrate before and after deposition of HA coating from scanning electron microscope and optical profiler. EDAX technique was employed to study the calcium to phosphorous ratio. Further, synchrotron based FTIR results will show the uniformity of structure of these coatings, composed of a individual crystals that appear matted, having dimensions resembling HA seen in natural bone. The crystal structure of these coatings was studied using glancing angle X-ray diffraction technique.
