Under distinct Performing conditions, hBN’s lubrication general performance exhibits clear strengths:
Less than seawater lubrication conditions, the friction coefficient from the Si₃N₄-10 vol% hBN friction pair may be as low as 0.03, and also the put on charge is as low as ten⁻⁶ mm/nm. This is often due to the complete effect of hydrodynamic lubrication and boundary lubrication of the area film formed by tribochemical response. Beneath total immersion water lubrication, the friction coefficient of the Si₃N₄-hBN/Si₃N₄ friction pair is usually as little as 0.01, which can be far lessen than that of pure Si₃N₄ (0.35 beneath the exact same conditions).
In distinction, Si₃N₄ has no apparent lubrication performance. Its friction coefficient is fairly large (usually 0.fifteen-0.35 under dry friction), and it ought to be employed with lubricating oil or grease in friction eventualities. Nonetheless, in high-temperature, substantial-pressure, or vacuum environments where lubricating oil can't be made use of, Si₃N₄’s friction and dress in complications will grow to be popular, which limits its application in a few Exclusive lubrication eventualities.
