Lubrication functionality will be the core benefit of hBN. Due to its layered crystal construction, the levels can slide freely less than external power, forming a steady lubricating movie on the surface area on the friction pair, which significantly decreases friction coefficient and don. Under distinct Performing disorders, hBN’s lubrication efficiency displays evident pros:
Under seawater lubrication circumstances, the friction coefficient in the Si₃N₄-10 vol% hBN friction pair could be as low as 0.03, and also the dress in charge is as low as ten⁻⁶ mm/nm. This is often due to the comprehensive outcome of hydrodynamic lubrication and boundary lubrication of your floor 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 effectiveness. Its friction coefficient is comparatively high (commonly 0.15-0.35 underneath dry friction), and it has to be made use of with lubricating oil or grease in friction situations. However, in substantial-temperature, high-force, or vacuum environments exactly where lubricating oil can't be used, Si₃N₄’s friction and dress in complications will grow to be popular, which limits its application in a few Exclusive lubrication eventualities.
