The next is a detailed comparison of their vital functionality indicators, assisting you immediately grasp the core discrepancies.
2.1 Lubrication Effectiveness: hBN Has an Undisputed Advantage
Lubrication effectiveness will be the core benefit of hBN. As a consequence of its layered crystal construction, the levels can slide freely under external power, forming a steady lubricating movie over the surface in the friction pair, which noticeably minimizes friction coefficient and use. Underneath different Functioning ailments, hBN’s lubrication general performance shows apparent rewards:
Underneath seawater lubrication ailments, the friction coefficient of your Si₃N₄-ten vol% hBN friction pair is often as little as 0.03, along with the don amount is as little as 10⁻⁶ mm/nm. This really is as a result of extensive impact of hydrodynamic lubrication and boundary lubrication from the surface movie formed by tribochemical response. Underneath entire 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 exact problems).
In contrast, Si₃N₄ has no evident lubrication functionality. Its friction coefficient is relatively superior (normally 0.fifteen-0.35 below dry friction), and it needs to be applied with lubricating oil or grease in friction scenarios. On the other hand, in large-temperature, superior-stress, or vacuum environments where by lubricating oil cannot be applied, Si₃N₄’s friction and put on challenges will become distinguished, which restrictions its application in some Specific lubrication eventualities.
It is well worth noting the addition of a little degree of hBN can Increase the densification process of Si₃N₄ composite ceramics to a certain extent, thereby strengthening the general Vickers hardness, but it really will also reduce the mechanical strength of Si₃N₄ to a certain extent.
