Hypothesis
Can water-based hexagonal boron nitride (hBN) effectively reduce the wear of diamond grains during the grinding of cast steel?
Conclusion
The study found that water-based hBN significantly reduces the maximum temperature during grinding and changes diamond grain wear from severe abrasion to slight micro-breaking.
Supporting Evidence
- The water-based hBN nanofluid reduced the maximum temperature at the contact zone from 408 K to 335 K.
- The use of hBN changed the wear of diamond grains from severe abrasion to slight micro-breaking.
- The flake of hBN improved the contact state between diamond grain and cast steel, reducing the friction coefficient from about 0.5 to 0.25.
Takeaway
This study shows that using a special liquid made from hBN can help diamond tools last longer when grinding metal by keeping them cooler and reducing wear.
Methodology
The study involved grinding experiments and molecular dynamics simulations to evaluate the effectiveness of water-based hBN as a lubricant.
