Optimizing bio-functional properties of Ti–Cu bone implants through introducing hierarchical structures

Titanium-copper alloys are attracting interest for biological applications, but are still limited by the instinctive bioinertness of the material processed by conventional methods, which limits their application as potential bone implants. In this work, the hierarchical structures of porous Ti–Cu im...

description Titanium-copper alloys are attracting interest for biological applications, but are still limited by the instinctive bioinertness of the material processed by conventional methods, which limits their application as potential bone implants. In this work, the hierarchical structures of porous Ti–Cu implants, which contain typical micro/nano sub-porous structure on the surface was successfully developed with the combination of the novel additive manufacture of laser powder bed fusion (L-PBF) and subsequent the micro arc oxidation (MAO) treatment. The high roughness, excellent hydrophilicity and the good match of mechanical properties were found on the micro/nano porous surface. And several compounds including TiO2-A, TiO2-R, CuO and Cu2O were also formed on the MAO-treated surface, which are all beneficial for the effectiveness improvement as biomaterials. The biological results conformed the obvious improvements in gain-of-function (GoF) of antibacterial properties and biological performances. All the samples for cell experiments exhibited a certain antibacterial function, in which no cytotoxicity and a significant promotion of the early adhesion for the MC3T3-E1 cells and BMSCs were detected in the MAO-treated samples.
