Hydroxyapatite deposits with a polycrystalline, crack‐free surface (see Figure for an SEM microimage) on stainless steel 316L substrates were obtained by a novel electrophoretic deposition (EPD) process. The procedure applies high voltage for very short times (0.5 to 1 s) thus avoiding structural agglomeration phenomena which prevail after 3 to 4 seconds under the same voltage. The dense packing of the nanoparticles affords very good sintering at 800 °C.
