Titanium alloy is a useful and widely used material, but it is particularly difficult to machine. Conventional flood cooling methods used to remove heat from and reduce friction in the work zone have many disadvantages. Minimum quantity lubrication (MQL) provides a quality alternative, but highly effective lubricants are needed for this method to be successfully used on titanium alloy. The two-dimensional material graphene has been proposed for use in nanolubricants. This study aims to investigate the tribological behaviors of graphene nanofluids and find the optimal concentration/base combination for MQL milling of titanium alloy.
