摘要: Abstract This study unleashes the potential of nanoporous connected networks as excellent oil reservoirs for reducing friction and wear in Al2O3-Al2O3 tribo-pairs. Alumina were fabricated via slip casting sintering to generate wide-ranging densifications (70–99.5%) slid a reciprocating flat-on-flat configuration. Friction coefficients (FCs) lie between 0.025 0.37 which decreased with an increase normal load (10–220 N), lubricant’s viscosity (19, 289 mPa·s) sliding frequency (6, 12, 24 Hz). A central finding is that FCs infused specimens are smaller than those surface lubricated. Wear rates from 10−5
