This work reports on the effect of particle size on the electrophoretic deposition ( EPD ) kinetics of submicrometer and nano‐sized hydroxyapatite ( HA ) employing a design of experiments strategy namely as response surface methodology ( RSM ). Zeta potential measurements and particle size analysis were used to study the electrostatic interaction between HA particles in an ethanol‐based suspension. The results of deposition kinetics under constant DC voltages showed a lower deposition rate for nano‐sized HA coating. Furthermore, the effects of voltage and time on EPD kinetics of HA coatings were quantified via RSM based on a central composite design ( CCD ).
