Lubrication efficiency is the core advantage of hBN. As a consequence of its layered crystal construction, the levels can slide freely less than external force, forming a steady lubricating movie over the surface on the friction pair, which noticeably decreases friction coefficient and don. Under various Doing work disorders, hBN’s lubrication overall performance displays evident advantages:
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 put on price is as low as ten⁻⁶ mm/nm. This is certainly mainly because of the comprehensive outcome of hydrodynamic lubrication and boundary lubrication of your floor film fashioned by tribochemical response. Below complete immersion h2o lubrication, the friction coefficient with the Si₃N₄-hBN/Si₃N₄ friction pair might be 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 evident lubrication functionality.
