Abstract
An oil-free water-based cutting fluid is disclosed. The cutting fluid comprises water, hexagonal boron nitride (hBN) particles, a dispersant, and a corrosion inhibitor. The hexagonal boron nitride (hBN) particles are hydrophilic particles having wettability in water. The hexagonal boron nitride (hBN) particle exhibits hydrophilicity solely through a heat-treatment synthesis process. The hexagonal boron nitride (hBN) particle exhibits hydrophilicity through dry surface treatment.
