An Overview of Sputtering Hydroxyapatite for BiomedicalApplication

Abstract Materials such as biocompatible metals, ceramics, composites, and polymers are used in the fabrication of biomedical implants which human body especially for replacement hard tissues. However, they degrade with time since subjected to different mechanical conditions long-term exposure fluids corrosion. Therefore, curb these limitations, surface properties usually coated thin metallic nonmetallic materials. One nonmetal is Hydroxyapatite (HA) coating has potential mitigating shortcomings it a bioactive material. This paper provides an overview existing literature on sputtering hydroxyapatite applications emphasis deposition parameters.
