Lubrication effectiveness is the Main benefit of hBN. Due to its layered crystal structure, the layers can slide freely under external force, forming a secure lubricating movie over the area of your friction pair, which significantly reduces friction coefficient and wear. Under different Operating circumstances, hBN’s lubrication overall performance exhibits obvious advantages:
Less than seawater lubrication disorders, the friction coefficient of your Si₃N₄-10 vol% hBN friction pair could be as little as 0.03, as well as don charge is as low as ten⁻⁶ mm/nm. This can be as a result of complete outcome of hydrodynamic lubrication and boundary lubrication with the surface area movie formed by tribochemical response. Below full immersion drinking water lubrication, the friction coefficient from the Si₃N₄-hBN/Si₃N₄ friction pair is usually as low as 0.01, which is significantly reduce than that of pure Si₃N₄ (0.35 underneath the identical conditions).
In contrast, Si₃N₄ has no noticeable lubrication functionality.
