On the corrosion behaviour of newly developed biodegradable Mg-based metal matrix composites produced by in situ reaction

Enhanced Mechanical Properties and Corrosion Behavior of Biodegradable Mg-Zn/HA Composite

“…In addition, according to the polarization curves, there was no rough appearance of the anodic curve, explaining the lack of associated repeated breakdown and regeneration of the passivation layer in regard to pitting corrosion. [18,42] …”

“…The agglomeration of HA particles was found to degrade the interfacial bonding strength between the matrix and reinforcement, leading to the formation of pores. [18] The pores became potential sites to be initially attacked by the media when the material was exposed to the corrosive environment. A higher amount and larger size of pores resulted in a higher rate of degradation.…”

The role of titania on the microstructure, biocorrosion and mechanical properties of Mg/HA-based nanocomposites for potential application in bone repair

“…Second, modification the surface of conventional Mg alloys via bioactive coatings including hydroxyapatite (HA, Ca 10 (PO 4 ) 6 (OH) 2 ) [22][23][24], Si [25,26], calcium-phosphorus [27], TiO 2 [28], bonelike apatite [29] and brushite [6]. Fabrication Mgmatrix composite (MMC) reinforced with bioactive ceramics [30] is another route to reduce degradation rate of Mg-based alloys. Bioactivity, biocompatibility, and osteo-conductivity of the calcium-phosphate (CaP) based bio-ceramics led to these bio-ceramics became attractive for the fabrication of Mg-based bio-composites as the additives [31][32][33].…”

Facile fabrication of hydrophobic surfaces on mechanically alloyed-Mg/HA/TiO2/MgO bionanocomposites

“…Gupta and co-workers [17] reported an improvement in the macrohardness and yield and tensile strengths of MgO-nanoparticlereinforced Mg/MgO composites. Accordingly, the combination of a metallic matrix and MgO could be an approach to fabricate a metal matrix composite as a biomaterial capable of full degradation [18].…”
