<p>This work investigates the effectiveness of graphene-based nanofluids and cryogenic lubrication on TiB whisker-reinforced Ti-5Al-4V matrix composite made using the spark plasma sintering (SPS) technique.

摘要

This work investigates the effectiveness of graphene-based nanofluids and cryogenic lubrication on TiB whisker-reinforced Ti-5Al-4V matrix composite made using the spark plasma sintering (SPS) technique. The process began with the compaction of the powders using the SPS method under high pressure. The influence of tool wear, tool life, and surface roughness was examined during turning operations under various lubricating conditions, including dry, graphene nano-MQL, and cryogenic lubrication. The turning process was carried out at three different levels of speed, feed rate, and depth of cut. From this study, it was observed that the tool experiences wear due to the friction of the contact surfaces. The results reveal that graphene nanofluids with minimum quantity lubrication reduce surface roughness and tool wear. Furthermore, this study indicates a shift in turning performance, showing that the tool life improves with graphene nano-MQL compared to cryogenic conditions. The HRSEM and TEM characterization, along with microhardness, were also investigated. This TiB whisker (TiBw)-reinforced Ti-5Al-4V composite is suitable for aerospace, defense, and biomedical applications.
