Lubrication functionality is definitely the Main benefit of hBN. On account of its layered crystal framework, the levels can slide freely under exterior drive, forming a secure lubricating movie over the area of your friction pair, which significantly minimizes friction coefficient and dress in. Below distinct Functioning situations, hBN’s lubrication functionality displays obvious rewards:
Less than seawater lubrication situations, the friction coefficient with the Si₃N₄-ten vol% hBN friction pair could be as low as 0.03, plus the put on level is as low as 10⁻⁶ mm/nm. That is as a result of in depth result of hydrodynamic lubrication and boundary lubrication in the surface movie formed by tribochemical response. Under whole immersion drinking water lubrication, the friction coefficient of the Si₃N₄-hBN/Si₃N₄ friction pair is often as low as 0.01, which happens to be much lower than that of pure Si₃N₄ (0.35 beneath the identical conditions).
In distinction, Si₃N₄ has no obvious lubrication general performance.
