Lubrication general performance is the core advantage of hBN. Resulting from its layered crystal structure, the layers can slide freely less than external power, forming a steady lubricating movie on the surface from the friction pair, which substantially minimizes friction coefficient and dress in. Below distinct Functioning situations, hBN’s lubrication performance displays obvious pros:
Less than seawater lubrication disorders, the friction coefficient with the Si₃N₄-10 vol% hBN friction pair may be as low as 0.03, and also the have on charge is as little as ten⁻⁶ mm/nm. This can be because of the comprehensive outcome of hydrodynamic lubrication and boundary lubrication with the surface area movie shaped by tribochemical response. Below entire immersion drinking water lubrication, the friction coefficient on the Si₃N₄-hBN/Si₃N₄ friction pair is usually as low as 0.01, that is much reduce than that of pure Si₃N₄ (0.35 underneath the similar disorders).
In distinction, Si₃N₄ has no clear lubrication functionality.
