Sonication Time Effect towards Stability of Al2O3/PAG and SiO2/PAG Nanolubricants

Sonication Time Effect towards Stability of Al2O3/PAG and SiO2/PAG Nanolubricants

Ultrasonication is the act of applying sound force to agitate particles in a sample with the frequency of more than 20 kHz. It is an external vibration induced during preparation of nanolubricant that helps the particles to overcome the van der Waals force bonding. Nanolubricant prepared is intended...
