2.1 Lubrication General performance: hBN Has an Undisputed Benefit
Lubrication general performance may be the Main benefit of hBN. As a result of its layered crystal composition, the levels can slide freely below external pressure, forming a secure lubricating movie around the surface area of your friction pair, which considerably lowers friction coefficient and have on. Below diverse Operating disorders, hBN’s lubrication overall performance shows evident advantages:
Under seawater lubrication situations, the friction coefficient on the Si₃N₄-10 vol% hBN friction pair could be as low as 0.03, as well as the dress in charge is as low as ten⁻⁶ mm/nm. This is often due to the complete effect of hydrodynamic lubrication and boundary lubrication of your area film formed by tribochemical response. Beneath total immersion water lubrication, the friction coefficient of your Si₃N₄-hBN/Si₃N₄ friction pair is often as low as 0.01, which is considerably decrease than that of pure Si₃N₄ (0.35 under the exact ailments).
In contrast, Si₃N₄ has no noticeable lubrication functionality.
