Less than distinct working ailments, hBN’s lubrication performance displays evident benefits:
Underneath seawater lubrication conditions, the friction coefficient in the Si₃N₄-ten vol% hBN friction pair is often as little as 0.03, as well as the dress in price is as little as 10⁻⁶ mm/nm. This really is because of the comprehensive outcome of hydrodynamic lubrication and boundary lubrication with the surface area movie formed by tribochemical response. Beneath full immersion h2o lubrication, the friction coefficient in the Si₃N₄-hBN/Si₃N₄ friction pair can be as little as 0.01, that is considerably reduced than that of pure Si₃N₄ (0.35 underneath the very same conditions).
In distinction, Si₃N₄ has no obvious lubrication effectiveness.
