The subsequent is an in depth comparison in their important functionality indicators, encouraging you rapidly grasp the core variances.
two.1 Lubrication Effectiveness: hBN Has an Undisputed Gain
Lubrication performance will be the Main benefit of hBN. As a consequence of its layered crystal composition, the levels can slide freely under exterior drive, forming a secure lubricating movie on the surface from the friction pair, which substantially lowers friction coefficient and don. Underneath diverse Functioning situations, hBN’s lubrication performance exhibits apparent benefits:
Under seawater lubrication conditions, the friction coefficient of the Si₃N₄-ten vol% hBN friction pair is often as low as 0.03, as well as the put on price is as little as ten⁻⁶ mm/nm. This can be as a result of extensive effect of hydrodynamic lubrication and boundary lubrication of the floor film fashioned by tribochemical response. Below full immersion drinking water lubrication, the friction coefficient in the Si₃N₄-hBN/Si₃N₄ friction pair may be as little as 0.01, which can be far lessen than that of pure Si₃N₄ (0.35 beneath the same ailments).
In contrast, Si₃N₄ has no noticeable lubrication functionality.
