Boron Nitride High Temperature Resistant Coatings muaj cov txiaj ntsig zoo
Aug 11, 2023
Boron nitride (BN) kub resistant coatings tau dhau los ua neeg nyiam nyob rau hauv ntau daim ntawv thov kev lag luam vim lawv cov khoom tshwj xeeb. Cov hauv qab no yog qee qhov zoo thiab siv BN kub resistant coatings.
Qhov zoo:
1. Thaum tshav kub kub tsis kam: BN txheej tuaj yeem tiv taus qhov kub thiab txias txog li 2000 degree, uas ua rau lawv zoo tagnrho rau siv nyob rau hauv high-temperature industrial puag ncig.
2. Tsis-wetting: BN coatings yog tsis-wetting, ua rau lawv siv tau nyob rau hauv daim ntaub ntawv uas cov ntaub ntawv uas siab melting point tau nyob rau hauv kev sib cuag nrog kub molten hlau thiab yuav tsum tau tiv thaiv los ntawm kev puas tsuaj.
3. Chemical stability: BN txheej yog inert thiab tsis hnov mob nrog cov tshuaj feem ntau, ua rau lawv zoo tagnrho rau siv nyob rau hauv acid thiab alkaline ib puag ncig.
4. Hluav taws xob rwb thaiv tsev: BN coatings muaj hluav taws xob rwb thaiv tsev zoo, ua rau lawv zoo tagnrho rau kev siv hluav taws xob rwb thaiv tsev.
5. High thermal conductivity: BN coatings muaj cov thermal conductivity siab, ua rau lawv muaj txiaj ntsig zoo hauv cov ntawv thov uas yuav tsum tau ua kom muaj txiaj ntsig zoo ntawm qhov chaw.
Kev siv:
1. Aerospace: BN txheej yog dav siv nyob rau hauv aerospace daim ntaub ntawv, qhov twg kub resistant txheej yuav tsum tau tiv thaiv aircraft thiab spacecraft los ntawm tshav kub puas.
2. Cov ntawv thov kev lag luam: BN txheej yog siv rau hauv kev lag luam xws li metallurgy, iav ua, thiab ceramics, qhov kub kub tiv thaiv txheej yog qhov tseem ceeb.
3. Hluav taws xob rwb thaiv tsev: BN txheej yog siv los ua cov khoom siv hluav taws xob hauv cov khoom siv hluav taws xob thiab hluav taws xob.
4. Kev lag luam tshuaj: BN txheej yog siv rau hauv kev lag luam chemical los tiv thaiv cov khoom siv thiab cov khoom siv los ntawm tshuaj lom neeg corrosion.
5. Cov khoom siv kho mob: BN txheej yog siv rau hauv cov khoom siv kho mob los txhim kho lawv cov biocompatibility, tiv thaiv corrosion, thiab kav ntev.
Nyob rau hauv xaus, BN kub resistant coatings muab tshwj xeeb zoo, xws li kub tsis kam, tsis-wetting, tshuaj stability, hluav taws xob rwb thaiv tsev, thiab siab thermal conductivity, uas ua rau lawv lug siv nyob rau hauv ntau yam kev siv.
