2.1 Lubrication Performance: hBN Has an Undisputed Benefit
Lubrication performance would be the Main benefit of hBN. As a consequence of its layered crystal construction, the layers can slide freely less than exterior force, forming a steady lubricating movie over the surface on the friction pair, which noticeably decreases friction coefficient and wear. Beneath unique working situations, hBN’s lubrication effectiveness shows obvious positive aspects:
Beneath seawater lubrication ailments, the friction coefficient with the Si₃N₄-ten vol% hBN friction pair is often as little as 0.03, along with the don amount is as low as 10⁻⁶ mm/nm. This really is as a result of extensive impact of hydrodynamic lubrication and boundary lubrication from the surface movie shaped by tribochemical reaction. Less than whole immersion drinking water lubrication, the friction coefficient in the Si₃N₄-hBN/Si₃N₄ friction pair could be as little as 0.01, and that is significantly reduced than that of pure Si₃N₄ (0.35 under the similar problems).
In contrast, Si₃N₄ has no noticeable lubrication functionality.
