Magnesium (Mg) is considered an attractive option for orthopedic applications due to its density and elastic modulus close to the natural bone of the body, as well as biodegradability and good tensile strength. However, it faces serious challenges, including a high degradation rate and, as a result, a loss of mechanical properties during long periods of exposure to the biological environment. Also, among its other weaknesses, it can be mentioned that it does not deal with bacterial biofilms. It has been found that making composites by synergizing its various components can be an efficient way to improve its properties. Among metal oxide nanoparticles, magnesium oxide nanoparticles (MgO NPs) have distinct physicochemical and biological properties, including biocompatibility, biodegradability, high bioactivity, significant antibacterial properties, and good mechanical properties, which make it a good choice as a reinforcement in composites. However, the lack of comprehensive understanding of the effectiveness of Mg NPs as Mg matrix reinforcements in mechanical, corrosion, and biological fields is considered a challenge in their application. While introducing the role of MgO NPs in medical fields, this article summarizes the most important results of recent research on the mechanical, corrosion, and biological performance of Mg/MgO composites.

“…This test was performed to determine the hardness and plastic deformation resistance of the coating on the bearing. In addition, a pin-on-disk wear test was carried out to determine the wear resistance of the created coating against friction and abrasive tools, using a load of 4.3 Kgf and a linear velocity of 10 m min −1 , according to ASTM G99 standard, over a distance of 3000 m [20]. To investigate the effect of coating on the chemical resistance and corrosion rate of the produced samples, a corrosion test was performed in oil solution at a temperature of 70 C for 60 min, according to ASTM G1 & G3 standards [21].…”

One of the solutions for improving the mechanical properties is coating them with particles, which is carried out by various methods. In this study, dual metallic copper/steel bearings were investigated so that, one of them was an uncoated (S0) and three coated samples, nickel micro-particles (S1), nickel/aluminum micro-particles (S2), and nickel/aluminum nano-particles (S3) were produced. The samples were subjected to mechanical tests including micro hardness, wear, and scratch, and then their corrosion rate and fatigue life were evaluated. The results showed that creating a nano-sized coating on the sample improved their properties compared to the micro-sized and uncoated samples. The highest micro hardness was obtained for sample S3, which was equal to 103.6 HV, 18% higher than sample S0. The lowest wear and corrosion rates were also obtained for sample S3, which were equal to 0.38 mg/m and 3.14 mm/year, respectively. Also, sample S3 had lowest delamination amount in the scratch test equal to 0.17 mm and most number of cycles until failure, 242 thousand cycles, in the fatigue test which was 76% more than the number of cycles spent on sample S0. Additionally, the microstructure of the corroded and worn surfaces of samples were examined by SEM imaging.

This study investigated the optimization of CuO and MgO nanoparticle reinforcement ratios within glass fiber‐reinforced polymer (GFRP) composites, and it examined the impact of the hybrid mixture of oxide powders on the mechanical properties of the GFRPs. The study aims to improve the mechanical properties of GFRPs by combining these two powerful nanofillers in various weight ratios to find the best combination to obtain the best fatigue life. Tensile‐tensile fatigue tests were conducted on 25 samples containing hybrid CuO and MgO nanoparticles ranging from 0.0 to 0.8 wt% in 0.2% increments. The test was conducted using a computer‐controlled servo‐hydraulic fatigue device. It was found that the GFRP composite reinforced with hybrid nanoparticles improved the fatigue life. The CuO proportion in the composites partially increased the brittleness properties, while the MgO proportion partially increased the stiffness according to the results. It was found that 0.6 wt% MgO–0.4 wt% CuO and 0.2 wt% MgO–0.6 wt% CuO GFRP composites demonstrated the highest fatigue life yielding at the 39.5k, and 13.7k cycle at 70%, and 80% load level, respectively. The best fatigue life was yielded at the 128k cycle with the 0.4 wt% MgO and 0.6 wt% CuO sample at the 60% load level. According to experimental hysteresis energy loss, 0.4 wt% MgO–0.2 wt% CuO GFRP composite was found to have the highest energy loss. The energy loss increased by approximately 51% in this composite compared to the non‐reinforced composite. The fracture surfaces of a fatigue sample were shown with the SEM image.Highlights The GFRP composites were produced by combining MgO and CuO as a hybrid reinforcement. Analyzed fatigue life using hysteresis curves and S–N graphs. The fatigue life of GFRP composites was improved with hybrid nanofiller content. As compared to separate reinforcements with CuO or MgO, the hybrid nanoparticle reinforcement enhanced fatigue life more.
