The subsequent is a detailed comparison in their important general performance indicators, supporting you rapidly grasp the Main differences.
2.1 Lubrication Performance: hBN Has an Undisputed Benefit
Lubrication general performance may be the Main benefit of hBN. Because of its layered crystal framework, the levels can slide freely less than external force, forming a stable lubricating film to the area of the friction pair, which drastically lessens friction coefficient and wear. Below diverse Doing the job circumstances, hBN’s lubrication functionality demonstrates evident pros:
Under seawater lubrication circumstances, the friction coefficient from the Si₃N₄-10 vol% hBN friction pair may be as low as 0.03, along with the use fee is as low as ten⁻⁶ mm/nm. This is due to the comprehensive outcome of hydrodynamic lubrication and boundary lubrication of your floor film fashioned by tribochemical response. Below full immersion h2o lubrication, the friction coefficient on the Si₃N₄-hBN/Si₃N₄ friction pair could be as little as 0.01, and that is much reduce than that of pure Si₃N₄ (0.35 underneath the very same circumstances).
In distinction, Si₃N₄ has no apparent lubrication performance.
