The following is a detailed comparison in their vital overall performance indicators, supporting you immediately grasp the core variations.
2.1 Lubrication Functionality: hBN Has an Undisputed Edge
Lubrication performance will be the core advantage of hBN. Because of its layered crystal framework, the levels can slide freely below external force, forming a stable lubricating movie around the surface from the friction pair, which substantially lowers friction coefficient and use. Beneath diverse Performing ailments, hBN’s lubrication effectiveness demonstrates evident rewards:
Beneath seawater lubrication situations, the friction coefficient in the Si₃N₄-10 vol% hBN friction pair is usually as little as 0.03, along with the dress in price is as little as 10⁻⁶ mm/nm. This really is because of the in depth influence of hydrodynamic lubrication and boundary lubrication in the surface 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.
