Underneath distinctive Operating ailments, hBN’s lubrication general performance exhibits clear pros:
Less than seawater lubrication circumstances, the friction coefficient from the Si₃N₄-10 vol% hBN friction pair may be as low as 0.03, and also the put on price is as little as ten⁻⁶ mm/nm. That is as a result of extensive result of hydrodynamic lubrication and boundary lubrication on the surface area movie shaped by tribochemical response. Beneath total immersion water lubrication, the friction coefficient of your Si₃N₄-hBN/Si₃N₄ friction pair is usually as low as 0.01, that is far lessen than that of pure Si₃N₄ (0.35 beneath the exact same conditions).
In distinction, Si₃N₄ has no apparent lubrication performance.
