The following is a detailed comparison in their vital overall performance indicators, serving to you quickly grasp the core variances.
two.one Lubrication General performance: hBN Has an Undisputed Advantage
Lubrication efficiency could be the Main benefit of hBN. Due to its layered crystal structure, the layers can slide freely below external force, forming a stable lubricating film around the surface area in the friction pair, which drastically lessens friction coefficient and have on. Less than different Operating circumstances, hBN’s lubrication efficiency exhibits apparent benefits:
Below seawater lubrication circumstances, the friction coefficient from the Si₃N₄-ten vol% hBN friction pair is often as little as 0.03, as well as the dress in price is as little as ten⁻⁶ mm/nm. This can be as a result of complete effect of hydrodynamic lubrication and boundary lubrication of your floor film fashioned by tribochemical reaction. Under whole immersion drinking water lubrication, the friction coefficient from the Si₃N₄-hBN/Si₃N₄ friction pair is usually as little as 0.01, that is considerably decreased than that of pure Si₃N₄ (0.35 under the exact problems).
In contrast, Si₃N₄ has no evident lubrication efficiency.
