“…GNPs, by possessing an atomic-scale barrier, are also favorable in reducing or suppressing H2 gas formation in Mg-based specimens during the degradation process when exposed to the body fluids, as presented in Figure 14 [47]. Neupane et al [140] revealed the improved anti-corrosion behavior of GNPs embedded in Mg substrates. The impenetrability and outstanding mechanical characteristics (1100 GPa) of GNPs make them suitable as an additive phase (reinforcement agent) embedded into the Mg matrix for implant applications.…”

“…Phosphate ions might slow down the corrosion rate significantly and postpone the occurrence of pitting corrosion [135]. Neupane et al [140] suggested the increased corrosion resistance of GNPs embedded within the Mg matrix. GNPs were successfully embedded into nanocomposites, which led to augmenting new bone generation and restoration because GNPs tend not to simply degrade in physiological fluids and anti-infiltrate corrosive media, thus reducing the degradation rate of the Mg-based composite [133].…”

“…GNPs were successfully embedded into nanocomposites, which led to augmenting new bone generation and restoration because GNPs tend not to simply degrade in physiological fluids and anti-infiltrate corrosive media, thus reducing the degradation rate of the Mg-based composite [133]. A Similar examination showed that [138][139][140] the corrosion performance of Mg-based composites was enhanced by the embedding of sufficient amounts of GFNs. Shuaia et al [102] fabricated a Mg alloy/GO composite with a 3D honeycomb nanostructure accompanied by remarkable corrosion resistance via the SLM process.…”

“…It should be mentioned that the volume fraction of GNPs in metal-based biomaterials ought to be in the amount of 1-10% due to the fact that a high concentration of GNPs results in dramatically elevated stiffness of the composite, which would possibly not be biomechanically suitable with natural bone. Neupane et al [140] revealed the improved anti-corrosion behavior of GNPs embedded in Mg substrates. The impenetrability and outstanding mechanical characteristics (1100 GPa) of GNPs make them suitable as an additive phase (reinforcement agent) embedded into the Mg matrix for implant applications.…”

Together with the enhancement of the load-bearing implant process for bone substitution and reproduction, an increasing requirement was observed concerning biodegradable magnesium and its alloys with lighter density and outstanding characteristics. Regardless of the current great potential of Mg utilization currently, the broader use of Mg alloys continues to be constrained by several natural causes, such as low resistance of corrosion, inadequate mechanical integrity during the healing process, and poor antibacterial performance. In this perspective, Mg-based composite encapsulated within graphene family nanomaterials (GFNs) such as graphene (Gr), graphene oxide (GO), graphene nanoplatelets (GNPs), and reduced graphene oxide (rGO) as reinforcement agents present great antibacterial activity, as well as cellular response and depicted numerous benefits for biomedical use. Magnesium matrix nanocomposites reinforced with GFNs possess enhanced mechanical properties and high corrosion resistance (low concentration graphene). It is worth noting that numerous elements including the production technique of the Mg-based composite containing GFNs and the size, distribution, and amounts of GFNs in the Mg-based matrix have a crucial role in their properties and applications. Then, the antibacterial mechanisms of GFN-based composite are briefly described. Subsequently, the antibacterial and strengthening mechanisms of GFN-embedded Mg-based composites are briefly described. This review article is designed to wrap up and explore the most pertinent research performed in the direction of Mg-based composites encapsulated within GFNs. Feasible upcoming investigation directions in the field of GFN-embedded Mg-based composites are discussed in detail.

Abstract. Micro arc oxidation (MAO) coating was first fabricated on AZ91 biomedical magnesium alloy and followed by surface laser treating. Effects of laser treating on surface characteristics of MAO coating were studied. The results indicated that after surface laser treating, the micro pores on MAO coating surface became fewer and smaller. The whole surface became more unique and compact. The surface quality of MAO coating was improved.

Current challenges in existing metallic biomaterials encourage undertaking research in the development of novel materials for applications in tissue engineering scaffolds and implants. This paper critically reviews the potential of carbon nanotubes (CNTs) and graphene as nanoreinforcements in metallic biomaterials for applications in tissue engineering scaffolds and implants. Unique and remarkable mechanical, electrical, and biological properties of these carbon nanomaterials allow their use as secondary-phase reinforcements in monolithic biometals for bone tissue engineering. The nanoscale dimensions and extraordinarily large
