Facile preparation of nanostructured octacalcium phosphate coatings on micro-arc oxidized magnesium with different functionalities for bone repair application

A drug-loaded composite coating to improve osteogenic and antibacterial properties of Zn–1Mg porous scaffolds as biodegradable bone implants

“…But, the rapid degradation rate and the release of hydrogen gas significantly limit their applications [ 15 ]. Although many measures, such as alloying design, surface modification and the preparation of Mg matrix composites, have been utilized to inhibit the degradation, the rapid degradation of Mg has not been satisfactorily addressed yet [ [16] , [17] , [18] , [19] , [20] ].…”

Roles of the micro‐arc oxidation coating on the corrosion resistance and mechanical properties of extruded Mg–2Zn–0.5Zr–1.5Dy (mass%) alloy

“…[13][14][15] It has been proved by many researchers that MAO coating can significantly improve the corrosion resistance of magnesium alloys and has no adverse effect on the human body. [16][17][18][19][20] Furthermore, the effect of MAO coating on the mechanical properties of the biodegradable magnesium alloys in the corrosive medium is also the direction to focus on, which is of great significance for the assessments of the practical application of the alloys. In this paper, MAO coatings with different morphologies and thicknesses were prepared on the surface of extruded Mg-2Zn-0.5Zr-1.5Dy (mass%) alloy by controlling the oxidation time of the MAO process.…”
