The following is an in depth comparison in their essential overall performance indicators, assisting you immediately grasp the core discrepancies.
2.1 Lubrication General performance: hBN Has an Undisputed Benefit
Lubrication general performance would be the Main benefit of hBN. As a consequence of its layered crystal structure, the layers can slide freely less than external power, forming a steady lubricating movie on the surface area of your friction pair, which considerably cuts down friction coefficient and wear. Beneath unique Performing situations, hBN’s lubrication effectiveness reveals obvious positive aspects:
Beneath seawater lubrication problems, 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 little 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 response. Underneath whole immersion drinking water lubrication, the friction coefficient from the Si₃N₄-hBN/Si₃N₄ friction pair can be as little as 0.01, that's much lower than that of pure Si₃N₄ (0.35 underneath the very same circumstances).
In distinction, Si₃N₄ has no clear lubrication efficiency.
