Biomimetic deposition of calcium phosphates onto Al₂O₃-ZrO₂ nanocomposites provides greater surface bioactivity, leading to the formation of biomaterials that can potentially replace and restore bone tissues. This study is aimed at evaluating the formation of different calcium phosphate phases using biomimetic coating on chemically treated and untreated surfaces of porous Al₂O₃-ZrO₂ (5 vol%) nanocomposites at different incubation times. To this end, the porous materials fabricated by gelcasting were calcined, sintered, chemically treated or left untreated, and biomimetically coated during a period of 14–21 days. The results indicated high porosity of the nanocomposite surfaces as well as high pore interconnectivity, which favours osseointegration. Additionally, it was observed that chemical treatment may influence the amount of calcium phosphates formed on the nanocomposite surfaces as well as the minimum incubation time, favouring the formation of a particular calcium phosphate phase over the nanocomposite surface.

磷酸钙仿生沉积在Al ₂ O ₃ -ZrO ₂纳米复合材料上可提供更大的表面生物活性，从而导致形成生物材料，从而有可能替代和恢复骨骼组织。这项研究旨在评估使用仿生涂层在多孔Al ₂ O ₃ -ZrO _2的化学处理和未处理表面上使用仿生涂层形成的不同磷酸钙相的形成。（5 vol％）纳米复合材料在不同的孵育时间下。为此，在14至21天的时间内，煅烧，烧结，化学处理或不处理通过凝胶浇铸制成的多孔材料，并进行仿生涂层。结果表明纳米复合材料表面的高孔隙率以及高的孔互连性，这有利于骨整合。另外，观察到化学处理可能影响在纳米复合材料表面上形成的磷酸钙的量以及最短的孵育时间，从而有利于在纳米复合材料表面上形成特定的磷酸钙相。
