Vim nws cov tawv tawv, tshuaj inertness , siab melting kub (2973 o C) cubic boron nitride yog siv los ua abrasive thiab hnav-resistant txheej. … BN raws li cov cuab yeej coj tus cwj pwm zoo ib yam li cov cuab yeej pob zeb diamond tab sis tuaj yeem siv rau ntawm cov hlau thiab cov pa roj carbon tsawg yam tsis muaj kev pheej hmoo ntawm cov tshuaj tiv thaiv vim CBN yog cov tshuaj inert.
boron nitride siv rau dab tsi?
Cov yam ntxwv tshwj xeeb ntawm Boron Nitride ua rau nws zoo tagnrho rau cov khoom siv los yog cov khoom siv jig rau sealing lossis brazing ua haujlwm hauv induction, nqus tsev thiab cua rauv; rau molten hlau crucibles; Kub dab dej thiab kub insulators.
Vim li cas boron nitride nrog cov qauv A tuaj yeem siv los ua roj nplua nyeem?
Lub anisotropy ntawm cov khoom siv kho tshuab imparts kev sib xyaw ntawm cov coefficient ntawm kev sib txhuam thiab siab nqa lub peev xwm rau boron nitride. Boron nitride tsim cov zaj duab xis lubrication ua raws li cov substrate nto.
cubic boron nitride yog dab tsi?
Polycrystalline cubic boron nitride (PCBN) yog Ameslikas tsim rau kev tig thiab machining ntawm cov cuab yeej hlau, cam khwb cia hlau thiab super alloys[3, 71]. PCBN yog cov khoom siv zoo tshaj plaws rau FSW ntawm cov alloys nyuaj xws li steels thiab titanium alloys [8]. …
Dab tsi yog cov khoom siv txiav nyuaj tshaj plaws?
pob zeb diamond. Cov ntaub ntawv nyuaj tshaj plaws, tab sis tsuas yog siv tau txog li 600°C thiab siv tsis tau rau tshuab hlau.
