HA/Ag Composite Coatings Prepared by Two-Step Electrodeposition
Abstract:
HA/Ag composite coatings were prepared by two-step electrodeposition in aquatic electrolytes containing calcium and phosphate ions and subsequently electroplating of silver in nicotinic acid bath.The influence of different working process on the content of silver in the coating,the influences of silver plating on the bonding strength and composition and structure of coating were investigated.The results show that the content of silver in the coating reduces and the densification degree of the coatings increases with decrease of the salt concentration,current density and with prolonging of the deposition time.The bonding strength of HA/Ag composite coating sare much greater than that of pure HA coatings.HA in coatings could be decomposed when the sintering temperature above 750℃,the reaction is obviously catalyzed by presence of silver.
