2.one Lubrication Overall performance: hBN Has an Undisputed Edge
Lubrication overall performance is definitely the core advantage of hBN. As a consequence of its layered crystal structure, the layers can slide freely underneath exterior force, forming a steady lubricating film over the surface in the friction pair, which noticeably decreases friction coefficient and don. Less than distinct Performing conditions, hBN’s lubrication efficiency displays noticeable positive aspects:
Beneath seawater lubrication ailments, the friction coefficient in the Si₃N₄-10 vol% hBN friction pair is often as low as 0.03, as well as the use fee is as low as 10⁻⁶ mm/nm. This is because of the extensive impact of hydrodynamic lubrication and boundary lubrication from the surface movie shaped by tribochemical response. Underneath entire immersion water lubrication, the friction coefficient of the Si₃N₄-hBN/Si₃N₄ friction pair can be as little as 0.01, which can be far lessen than that of pure Si₃N₄ (0.35 beneath the identical circumstances).
In distinction, Si₃N₄ has no clear lubrication overall performance.
