The subsequent is a detailed comparison of their critical overall performance indicators, serving to you quickly grasp the core distinctions.
2.1 Lubrication Effectiveness: hBN Has an Undisputed Gain
Lubrication performance may be the core advantage of hBN. On account of its layered crystal framework, the levels can slide freely beneath exterior power, forming a steady lubricating film within the surface area in the friction pair, which drastically lowers friction coefficient and don. Underneath unique Performing disorders, hBN’s lubrication general performance reveals evident strengths:
Underneath seawater lubrication problems, the friction coefficient in the Si₃N₄-10 vol% hBN friction pair is usually as little as 0.03, as well as the put on rate is as little as 10⁻⁶ mm/nm. This is due to the in depth result of hydrodynamic lubrication and boundary lubrication with the surface film formed by tribochemical response. Under full immersion water lubrication, the friction coefficient of the Si₃N₄-hBN/Si₃N₄ friction pair may be as low as 0.01, that is far reduce than that of pure Si₃N₄ (0.35 under the same conditions).
In distinction, Si₃N₄ has no noticeable lubrication general performance.
