The next is an in depth comparison of their vital effectiveness indicators, aiding you quickly grasp the core differences.
2.one Lubrication Overall performance: hBN Has an Undisputed Edge
Lubrication efficiency is definitely the core advantage of hBN. As a consequence of its layered crystal construction, the layers can slide freely less than external force, forming a steady lubricating movie over the surface on the friction pair, which significantly decreases friction coefficient and don. Under distinct Performing conditions, hBN’s lubrication efficiency demonstrates noticeable advantages:
Under seawater lubrication situations, the friction coefficient on the Si₃N₄-10 vol% hBN friction pair could be as low as 0.03, along with the use amount is as little as 10⁻⁶ mm/nm. This can be a result of the detailed influence of hydrodynamic lubrication and boundary lubrication with the floor film fashioned by tribochemical response. Beneath total immersion water lubrication, the friction coefficient of the Si₃N₄-hBN/Si₃N₄ friction pair is usually as little as 0.01, which can be far lower than that of pure Si₃N₄ (0.35 underneath the very same situations).
In distinction, Si₃N₄ has no clear lubrication efficiency. Its friction coefficient is relatively significant (normally 0.fifteen-0.35 beneath dry friction), and it must be made use of with lubricating oil or grease in friction situations. However, in significant-temperature, higher-tension, or vacuum environments in which lubricating oil can not be utilized, Si₃N₄’s friction and don issues will develop into notable, which boundaries its software in certain Unique lubrication situations.
It can be really worth noting the addition of a small number of hBN can Increase the densification process of Si₃N₄ composite ceramics to a certain extent, thereby bettering the overall Vickers hardness, but it surely will also reduce the mechanical strength of Si₃N₄ to a certain extent.
