Abstract
A combination of an analytical solution and experimental tests was used in this study to evaluate the wear resistance of a porous functionally graded material (PFGM) structural system.A cylindrical porous sample is fabricated using 3D printing technology based on different parameters. According to ASTM standards, the sliding wear behavior of porous samples has been investigated using a Pin on the Disc Tribometer. The results showed reasonable agreement between experimental and analytical analyses, with a discrepancy of 10.434 %. This indicates that 3D printing can be suitable for manufacturing reliable viscoelastic samples. However, the porosity parameter has a significant influence on wear resistance. The porous gradation technique led to a higher experimental wear resistance of around 31% for FGM PLA samples.Morphological observation on specimen fracture surfaces was done using a scanning electron microscope (SEM) to check the PFGM layer’s nature.
