Surface modification and biocompatibility of Ni-free Zr-based bulk metallic glass

An innovative technique to simply fabricate ZrO2–HA–TiO2 nanostructured layers

“…The most important advantage of the MAO-derived layers is that they are not only porous, but also uniformly coated on metal surfaces with complex geometry. Moreover, MAO coatings usually exhibit good adhesion to substrates [43][44][45][46][47]. It is known that MAO involves in more complex plasma-enhanced physico-chemical processes, including micro-arc discharge, diffusion, plasma chemical reactions, and cataphoretic effects, in which micro-arc discharge can generate high temperature in the discharge channels, sintering the subsequent processes formed coatings [48].…”

The effect of chemical treatment on apatite-forming ability of the macroporous zirconia films formed by micro-arc oxidation

“…Moreover, MAO coatings usually exhibit good adhesion to substrates. Although MAO modification of zirconium and its www.elsevier.com/locate/apsusc Available online at www.sciencedirect.com alloys was recently performed as described in details elsewhere [16][17][18][19], the obtained films were always filled with cracks on their surfaces. In our previous work [20,21], zirconia films containing Ca and P on zirconium were obtained by MAO in electrolytes containing calcium acetate monohydrate and bglycerophosphate disodium salt pentahydrate.…”

Potential Prospective Application of Zr-Based Bulk Metallic Glasses in Dental Implant

“…The treatment BMGs could show a good activity through microarc oxidation technology. Liu et al 64,65) investigated the bioactivity of the MAO-treated samples which were immersed into simulated body fluid, and found that a bone-like apatite layer was successfully deposited on the surface of the Ni-free Zr 60.5 Cu 19.5 Fe 5 Al 9.5 Ti 5.5 . Through performing bioactive Ca titanate coatings on a Zr-based bulk metallic glass by laser cladding, the CaTiO 3 can spontaneously form the apatite on its surface when soaked in simulated body fluid to make the Zr-based BMGs surface bioactive.…”
