The effect of 3 main influencing factors, namely current density, electroplating time and silver solution composition, on the structure and properties of the coating was investigated. The SEM data indicated that the average size of silver grains was about 20 µm. The optimal parameters for electrodeposition were AgNO 3 concentration of 0.05 M, current density of 0.5 A/dm 2 and plating time of 10 minutes. The optimal coating had lower silver ion release in simulated body fluid although the silver weight of this coating was higher than that of other coatings. Antibacterial efficiency of this coating was over 92 % in 60 min (against Escherichia Coli bacteria). After immersion for 168 h in simulated body fluid, concentration of silver released is not toxic to human body.
