Numerous HA composite coatings are analyzed in-terms of better biocompatibility, corrosion resistance behavior, with mechanical strength. In order to fulfill the condition of better biomaterial for long term solicitations, the following future work are to be carried out, - In-vitro degradation studies implant surfaces for longer immersion time in physiological body fluids solutions.- Drug delivery evaluations of HA composites coatings for biomedical applications- In-vivo examination of developed HA composite coatings on proper animal model
