Chemical anchorage of Hydroxyapatite on 316LSS using a ZrO2 interlayer for orthopedic prosthesis applications

film previously deposited by electrophoresis on 316LSS substrates. The bilayer system was thermally annealed at temperatures less than or equal to 700 °C for a maximum time of 5 minutes. The electro-deposited amorphous layers of zirconium hydroxide with a thickness about 8 µm showed good adherence to the stainless steel substrates and allowed good chemical anchorage with the HA layer after the thermal treatment, producing a thin layer of zirconia stabilized in tetragonal and monoclinic mixed phases. The thermal treatment also degraded HA layer to form calcium phosphates. The bilayer system of HA/ZrO
