چکیده انگلیسی
This study examined the characteristics of calcium phosphate coatings formed on untreated and H2O2-treated titanium substrates by electrodeposition in a modified simulated body fluid (SBF). A porous coating comprising of mainly hydroxyapatite (HA) was formed on the H2O2-treated titanium substrate by electrodeposition. This coating was transformed into carbonate and calcium-deficient HA layers with a bonelike crystallinity during immersion in the SBF. However, a uniformed coating comprising of amorphous calcium phosphate (ACP) formed on the untreated titanium substrate by electrodeposition was transformed into poorly crystalline HA during immersion in the SBF. This difference was attributed to the increased surface area of the titanium substrate after the H2O2 treatment as well as the OHâ ions released from this modified surface during electrodeposition. Therefore, it was shown that the H2O2 treatment prior to electrodeposition may be an effective method for preparing a potentially bioactive calcium phosphate coating by electrodeposition.
