“…In this technique, a constant current of 400 Amp, argon gas pressure of 40 Psi and varying hydrogen pressure of 5 Psi and 10 Psihave been used to prepare the aluminium-cenosphere composite foam with the dimension of 10x10x5 mm 3 . The detailed experimental step followed in this study has been reported elsewhere [23]. The samples were sliced to 10-12 pieces and the cross sections of the spray formed coupons (thickness of 5 mm) were subjected to all characterization as mentioned in the paper.…”

The present work aims at understanding the effect of process parameters on the porosity and forming route. A detailed investigation of the microporosity and nano have been undertaken through microcomputer tomography (µ respectively. The µ maximum of CF have been by nanoindentation analysis and compared with commercially pure (CP) aluminium. The sphericity results of the foam show that the pores are near spherical (with a sph diameter is below 50 µm, beyond which, the sphericity index decreases (0.175 to 0.4). The results of nanoindentation (for CP aluminium) to 673±54 MPa and energy absorption from 86±10 however; it decreases the elastic modulus from 58±3 (for CP

“…The findings indicate that incorporating cenosphere space holders results in reduced relative density, increased hardness, and enhanced wear properties when compared to solid aluminum counterparts. Examinations of wear on the foam demonstrate a substantial improvement in wear resistance compared to commercial aluminum [12]. Current work will be concentrated on enhancing the mechanical properties with a primary emphasis on wear resistance of Al-foam produced by (SDP) To further enhance the foam's wear resistance, specific additives (Mg metal powder) will be incorporated into the aluminum mixture prior sintering process.…”

In the present study, the production of aluminum foam was carried out using the powder metallurgy technique, specifically employing the sintering – dissolution process (SDP). The SDP method, which constitutes a sequential series of four well-defined steps, was employed to achieve the desired foam structure and properties. These steps involved carefully controlling the parameters and conditions throughout the process to ensure successful foam formation. Aluminum powder with a particle size of (1.99 μm) as a raw material was mixed with NaCl with a particle size between (150-425μm) used as a space holder at different ratio (25, 35, 45and 55 wt. %.). Obtained Al-foam with 45% NaCl demonstrated the most optimal structure. Some additives (Mg) added to the powder mixture, it was found that the mechanical and the tribological properties of the produced foam were improved. The introduction of metal’s micro-particles led to a notable enhancement in both compressive stress and micro-hardness, the compressive stress increased substantially from 15.2 MPa to 56.5 MPa for the foam containing 45% NaCl and 45% NaCl + Add., respectively. While the micro-hardness exhibited a noteworthy increase from 51.5 HV to 62.1 HV. Results also showed important reduction in the wear rate from (0.00000155 g/cm) to (0.00000079 g/cm) for the Al-samples of (45% NaCl) and (45% NaCl+ Additive) respectively, the lowest value recorded for the coefficient of friction was (0.15) for (Al-Foam with 45% NaCl + Additive) compare to (0.19) and (0.21) for (Al-foam with 45% NaCl) and (pure Al) respectively at 10 N applied load and 800 rpm.
