The properties of hydroxyapatite ceramic coatings produced by plasma electrolytic oxidation
Calcium phosphate coatings produced on the surface of Ti6Al4V by plasma electrolytic oxidation (PEO) using different concentrations of hydroxyapatite (HA) in a 0.12 M Na3PO4 (NAP) electrolyte solution was investigated. It was found that the amount of calcium phosphate particles infiltrated into th...

description |
Calcium phosphate coatings produced on the surface of Ti6Al4V by plasma electrolytic oxidation (PEO) using
different concentrations of hydroxyapatite (HA) in a 0.12 M Na3PO4 (NAP) electrolyte solution was investigated.
It was found that the amount of calcium phosphate particles infiltrated into the coating layer as well as the
thickness and the surface roughness of the coating increased with increasing HA concentration. The porosity of
the ceramic coatings indicated an inverse relationship with the concentration of HA particles dispersed in the
NAP solution. The result also demonstrates that higher scratch adhesive strength was achieved using 1.5 g/L HA
solution, producing a critical load of 2099 mN, while 0 g/L HA only produced a critical load of 1247 mN. The
adhesion becomes independent of thickness when the concentration of HA exceeds 1.5 g/L. The failure of the
coating was characterized by large periodic hemispherical chipping, while intermittent delamination was noticed
with the coating embedded with HA particles. This study demonstrate the viability of using PEO to produce
a thin layer of HA ceramic coating on Ti6Al4V suitable for biomedical applications. |
