Underneath distinctive Operating problems, hBN’s lubrication effectiveness reveals obvious benefits:
Below seawater lubrication problems, the friction coefficient on the Si₃N₄-10 vol% hBN friction pair might be as low as 0.03, as well as the dress in charge is as low as ten⁻⁶ mm/nm. This is often mainly because of the extensive impact of hydrodynamic lubrication and boundary lubrication with the floor film fashioned by tribochemical response. Below complete immersion h2o lubrication, the friction coefficient with the Si₃N₄-hBN/Si₃N₄ friction pair might be as low as 0.01, which happens to be significantly decrease than that of pure Si₃N₄ (0.35 under the similar problems).
In contrast, Si₃N₄ has no clear lubrication efficiency.
