This
study
explores
the
grindability
and
sustainability,
focusing
on
tribological
lubrication
capabilities
of
water-soluble
hybrid
nanofluid
under
minimum
quantity
(MQL)
conditions
during
grinding
Nimonic-90.
Nanofluids
were
prepared
by
adding
0.25%,
0.75%,
1.25%
volumetric
concentrations
Al2O3,
GnP
nanoparticles
into
deionized
(DI)
water.
The
thermal
conductivity,
contact
angle,
dynamic
viscosity
nanofluids
characterized.
Specific
tangential
forces,
specific
normal
coefficient
friction,
surface
roughness
reduced
approximately
37%,
25%,
17%,
11%,
respectively,
compared
to
pure
Al2O3
based
29%,
14%,
12%,
relative
nanofluid.
Consequently,
a
0.75%
concentration
water-based
emerged
as
most
promising
cutting
fluid.
