Wear behavior of textured tools under graphene-assisted minimum quantity lubrication system in machining Ti-6Al-4V alloy

摘要

Wear behavior of textured tools while turning Ti-6Al-4V under dry, minimum quantity lubrication (MQL) using canola oil and MQL using graphene blended in canola oil environment was discussed in this work. The tool wear and surface roughness were characterized to evaluate the textured tool's performance. It was revealed that the MQL (graphene mixed in canola oil) showed better results followed by MQL (only canola oil) and then dry condition. The excellent performance of graphene based MQL was mostly due to high thermal conductivity and shearing behavior of graphene. An increased shear angle (11-30%) and reduced coefficient of friction (16-39%) under graphene environment have contributed for enhanced performance of graphene-based MQL.
