Study of the Effect of Adding Nano Carbon on the Structural Properties of Aluminum Pistons Manufactured Using Powder Technology

The structural properties of carbon-reinforced aluminum compounds with different weight ratios (0, 0.01, 0.02 g) of carbon in aluminum pistons prepared by powder metallurgy were studied. X-ray diffraction (XRD) results were conducted for the pistons under study. The results showed that the formed crystals were polycrystalline and had a cubic structure with a preferential orientation along the (111) plane. It was found that the diffraction peaks improved, indicating greater microstructural homogeneity with increasing reinforcing ratios. The crystallite size (Cs) of the samples was also calculated and found to decrease with increasing nanocarbon support. The surfaces of the samples were also examined using scanning electron microscopy (SEM), which revealed grain growth and distribution, as well as variations in surface morphology resulting from the nanocarbon reinforcement process.
