For foreign trade buyers, the Main need for selecting products will be to match effectiveness with application eventualities. The most important difference between hBN and Si₃N₄ lies of their practical orientation: hBN concentrates on lubrication, electrical insulation, and substantial-temperature resistance, whilst Si₃N₄ concentrates on mechanical reinforcement, dress in resistance, and structural steadiness. The next is an in depth comparison of their critical efficiency indicators, helping you speedily grasp the Main distinctions.
two.one Lubrication Functionality: hBN Has an Undisputed Gain
Lubrication functionality is the core advantage of hBN. As a consequence of its layered crystal construction, the layers can slide freely underneath exterior drive, forming a stable lubricating film about the floor of the friction pair, which substantially lessens friction coefficient and wear. Below diverse Doing the job conditions, hBN’s lubrication efficiency displays evident pros:
Less than seawater lubrication conditions, the friction coefficient from the Si₃N₄-10 vol% hBN friction pair can be as little as 0.03, and the wear rate is as little as 10⁻⁶ mm/nm. This can be a result of the thorough impact 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, that's far lessen than that of pure Si₃N₄ (0.35 beneath the exact same conditions).
In distinction, Si₃N₄ has no apparent lubrication performance. Its friction coefficient is fairly higher (ordinarily 0.15-0.35 less than dry friction), and it has to be used with lubricating oil or grease in friction situations. However, in significant-temperature, higher-force, or vacuum environments exactly where lubricating oil can't be made use of, Si₃N₄’s friction and dress in complications will grow to be popular, which limits its application in a few Exclusive lubrication eventualities.
It's value noting the addition of a little level of hBN can Enhance the densification strategy of Si₃N₄ composite ceramics to a particular extent, thus enhancing the overall Vickers hardness, nevertheless it can even decrease the mechanical energy of Si₃N₄ to a particular extent.
