Under distinct Performing conditions, hBN’s lubrication efficiency displays evident pros:
Less than seawater lubrication conditions, the friction coefficient from the Si₃N₄-ten vol% hBN friction pair can be as little as 0.03, and the wear rate is as little as 10⁻⁶ mm/nm. That is due to detailed result of hydrodynamic lubrication and boundary lubrication in the surface movie shaped by tribochemical reaction. Less than whole immersion drinking water lubrication, the friction coefficient from the Si₃N₄-hBN/Si₃N₄ friction pair can be as little as 0.01, which can be far lessen than that of pure Si₃N₄ (0.35 beneath the exact same conditions).
In distinction, Si₃N₄ has no noticeable lubrication functionality. Its friction coefficient is comparatively high (ordinarily 0.15-0.35 underneath dry friction), and it has to be used with lubricating oil or grease in friction situations. However, in substantial-temperature, higher-force, or vacuum environments where lubricating oil can't be made use of, Si₃N₄’s friction and put on challenges will turn out to be outstanding, which limits its application in some Specific lubrication eventualities.
It is value noting the addition of a little degree of hBN can Increase the densification process of Si₃N₄ composite ceramics to a certain extent, thereby bettering the overall Vickers hardness, nonetheless it can even lessen the mechanical energy of Si₃N₄ to a particular extent.
