Lubrication Performance of Few-layer Graphene Modified Castor Oil during Tapping ADC12 Aluminum Alloy
The aim of this work is to explore the feasibility of using few-layer graphene in order to improve the lubrication performance of castor oil at high pressure and high temperature.Five different mass fractions of castor oil-based nanofluids were prepared through ultrasonic oscillation.With the aid of MQL technique, these nanofluids were used as lubricants during the internal tapping process of ADC12 aluminum alloy.The tapping torque curves were real-time recorded.The result implies that both the mean and maximum torque values obtained with nanofluids MQL are lower than that of pure castor oil MQL.This reduction in torque shows a U-shaped trend with the increasing additive concentration.Specifically, the use of 0.5wt% nanofluid MQL can reduce the mean torque value by 11.4% and the maximum torque value by 12.2% when compared to pure castor oil MQL.The mechanism of load-reducing ability of few-layer graphene was later discussed in this work.
