Hydroxyapatite (HA) powder is now available as a bioceramic precursor for numerous biomedical implants. Since it has excellent bioactivity, biocompatibility, and osteointegration properties, it can be formed in bulk or as a coating on metallic substrates. The current study focused on controlling temperature and stirring rates utilizing electrophoretic deposition (EPD) in nitric acid colloidal solutions for coating HA powder on stainless steel (SS316L). A fixed set of operating parameters, such as colloidal solution concentrations and compositions, electric fields, and deposition times, were used in this EPD experiment. XRD qualitative examination revealed the formation of tricalcium phosphate (-TCP) from hydroxyapatite decomposition on the surface coating. The operating settings have a considerable impact on the yields of deposition materials. This -TCP layer coating is the potential to improve biocompatibility as a biomedical implant.
