Investigation of the Effects of Nanoparticle Additive Lubricants on the Adhesive Wear Properties of Al2024

The adhesive wear behaviour of Al2024 aluminium alloy lubricated with oils modified with nanoparticles was examined in this work. The popular industrial 10W40 motor oil was chosen as the lubricant, and titanium carbide (TiC) and titanium nitride (TiN) nanoparticles were added at weight concentrations of 1%, 3%, and 5% to enhance the tribological characteristics. The nanoparticles and lubricants were combined evenly, and the pin-on-disk method was used to test the samples' resistance to wear. Following tests with predetermined parameters, a detailed analysis of the worn surfaces was performed using techniques from SEM, FT-IR, and optical microscopy. The findings showed that adding nanoparticles improved wear resistance and decreased the coefficient of friction. On Al2024 specimens, the addition of 3% TiN and TiC nanoparticles in particular resulted in more uniform surface deformation and smaller wear tracks. Significant results from this study demonstrate the potential of lubricants reinforced with nanoparticles to increase machine performance and service life in industrial settings.
