Abstract
The invention discloses micron-nano pore gradient oxide ceramic films with biological activity, which are prepared by the following methods: The surface structures are biomedical engineering materials; Inorganic precursor coating solutions or the organic precursor coating solutions are prepared with or without micron and nanopore additives; The surface structures of the substrate are treated in the following steps: (1) The surfaces of the substrate are coated by the inorganic precursor coating solutions or the organic precursor coating solutions with or without micron and nanopore additives; (2) The substrate with coatings are dried, sintered, naturally cooled, and cleaned. (3) The biomedical engineering materials with the micron-nanopore gradient oxide ceramic films, especially biomimetic micro-nanoporous gradient alumina film, yttrium partially stabilized zirconia film, and alumina doped yttrium partially stabilized zirconia films in this invention greatly improve biocompatibility and biological activity.
