Study of hybrid nanofluids of TiO2 and montmorillonite ...

2021-7-18  In our previous work [ 21] montmorillonite (MMT) clay NPs were added to a cutting fluid for milling of AISI 1018 steel and an optimization by RSM was performed for improving multi-response characteristics. Here, the proposed tribological enhancing mechanism was due to the exfoliation of the NPs layers between sliding surfaces.
