In this study, Cu-matrix hybrid nanocomposites with varying amounts of silicon carbide (SiC) and fly ash nano particles were created using the powder metallurgy process. To describe the microstructure of produced powders, X-ray diffraction (XRD) technique and transmission electron microscopy (TEM) were used. The powders were compressed and fired for one hour in inert gas at three different temperatures up to 850 °C. Moreover, the sintered samples’ microstructure, mechanical, wear, thermal, and electrical characteristics were examined. According to the results, particle sizes were successfully decreased up to 51.2 nm by adding SiC and fly ash ceramics. The values of density, coefficient thermal expansion (CTE) and electrical conductivity of the nanocomposite sample containing 16 vol% of ceramics decreased until reached 92.3%, 9.5 × 10−6/°C and 7.44 × 106 S m−1, respectively. Additionally, as compared to Cu matrix (CSF0), the nanocomposite with the highest ceramics volume percentage (CSF8) significantly improved in terms of ultimate strength, microhardness, Young’s modulus, and wear rate by 47.8, 88, 23.5and 27.3%, respectively.

“…They have bone-bonding ability via the formation of a hydroxyapatite layer on their surface and induce angiogenesis [4,5]. To improve their low fracture toughness, which is thought to be the main drawback that restricts the use of BG in load-bearing site applications, polymers, and metal oxides are frequently added to BG [6][7][8][9][10][11][12]. Researchers have attempted to improve the mechanical strength and hardness of burglars, by incorporating different materials into them, including polymers, carbon fibers, and metal oxides [13][14][15].…”

In this study, the bioactivity and the mechanical properties (Mechanical compressive strength, Hardness, and density) of bioglass (BG) and bioglass/graphene oxide (BG/GO) were investigated. Bioglass in chemical composition [60SiO2_35CaO_5P2O5] was prepared via the sol–gel method. GO was added to the bioglass (BG) with different contents (0.5, 1, 2, and 3) wt.% named as 0.5%GO, 1%GO, 2%GO, and 3%GO samples respectively. The synthesized specimens were characterized by several techniques Fourier Transform Infrared (FT-IR), X-Ray Diffraction (XRD), and Scanning Electron Microscopy (SEM). Compressive strength, Hardness, and density were studied also by different techniques to obtain the optimum Mechanical samples. The biological activity was studied by an in-vitro test in simulated body fluid (SBF) for 33 days. Results showed that: the 0.5%GO sample exhibited optimum mechanical compressive strength by approximately 82% compared to the BG sample. Hardness was increased from 0.5%GO sample up to 1%GO sample compared to BG sample and gradually decreased in 2%GO Sample and 3%GO. Bioactivity results showed deposition of HA layer on the bioglass surface and there was no significant change in it with the addition of graphene oxide.
