“…During this heat treatment process, hard precipitates are finely and uniformly distributed in the soft phases of the matrix, leading to the increased strength of the alloy. The most important requirements for carrying out the age-hardening process on alloys are the limited solubility of precipitates or hard secondary phases in the alloy matrix and the decrease in this solid solubility with decreasing temperature [76][77][78]. The precipitation hardening process depends on the temperatureinduced change in solid solubility and produces impurity phase particles that inhibit the movement of dislocations and defects in the crystal lattice, contributing to the hardening of the material [52,79].…”

As a smart implant, magnesium (Mg) is highly biocompatible and non-toxic. In addition, the elastic modulus of Mg relative to other biodegradable metals (iron and zinc) is close to the elastic modulus of natural bone, making Mg an attractive alternative to hard tissues. However, high corrosion rates and low strength under load relative to bone are some challenges for the widespread use of Mg in orthopedics. Composite fabrication has proven to be an excellent way to improve the mechanical performance and corrosion control of Mg. As a result, their composites emerge as an innovative biodegradable material. Carbon nanotubes (CNTs) have superb properties like low density, high tensile strength, high strength-to-volume ratio, high thermal conductivity, and relatively good antibacterial properties. Therefore, using CNTs as reinforcements for the Mg matrix has been proposed as an essential option. However, the lack of understanding of the mechanisms of effectiveness in mechanical, corrosion, antibacterial, and cellular fields through the presence of CNTs as Mg matrix reinforcements is a challenge for their application. This review focuses on recent findings on Mg/CNT composites fabricated for biological applications. The literature mentions effective mechanisms for mechanical, corrosion, antimicrobial, and cellular domains with the presence of CNTs as reinforcements for Mg-based nanobiocomposites.

“…But the increased content of graphene in the composite samples, with 0.35 wt% and 0.45 wt% of graphene, might increase the hardness of these samples and also might restricted impingement of abrasive particles in to the sample surface. The embedded graphene particles in the ceramic composite from the top surface of the samples might be exposed on to the wear track during reciprocating movement of pin during wear test and there by aiding for formation of lubricating tribofilm [22][23][24]. This self-lubricating property of graphene might restricted the higher damage in 0.35 wt% and 0.45 wt% of graphene reinforced alumina composite samples and reduced the wear rate and COF enormously when compared with other samples.…”

Ceramic materials are of technical and commercial importance and can meet many engineering requirements owing to their thermal, chemical and mechanical performance. Due to its high density and hardness, alumina (Al2O3) is one of the main materials in this category that can be used to produce critical parts. An example of such an application is wear and abrasion resistance. The fabrication root technique and a suitable secondary reinforcement material can enhance a ceramic's wear characteristics. Hence the present work is mainly concentrated on the preparation of alumina ceramic composite material reinforced with different weight proportions of graphene ranging from 0.15wt% to 0.45 wt% (with an interval of 0.1) and fabrication through microwave sintering method. Wear studies are performed on graphene reinforced alumina ceramic material samples using pin-on-disk apparatus at different loads of 5N, 10N, 15N keeping speed of 0.8 m/sec and sliding distance of 40 m constant. The obtained wear results are compared with wear performance of pure alumina samples which are prepared in the same condition. Wear tests even at higher load of 15N revealed that the decrease in wear rate of the composite samples reinforced with 0.35 wt% of grapheme is 35.14% and in the composite samples reinforced with 0.45 wt% of graphene is 34.85% when compared with wear rate of monolithic alumina samples. The effect of different wt%s of graphene on wear properties of obtained ceramic composite is also studied through SEM analysis.
