Yuav Ua Li Cas Ntsuas Cov Khoom Antioxidant ntawm Boron Nitride Coatings

Yuav Ua Li Cas Ntsuas Cov Khoom Antioxidant ntawm Boron Nitride Coatings

Boron Nitride coatings tau txais txiaj ntsig zoo nyob rau lub sijhawm tsis ntev los no vim lawv cov khoom ntawm lub zog thiab thermal stability. Cov coatings no tau siv dav hauv kev lag luam sib txawv thiab paub txog lawv cov kev ua tau zoo nyob rau hauv huab cua. Ib qho kev txhawj xeeb tseem ceeb thaum siv cov txheej txheem no yog lawv cov kav ntev tiv thaiv oxidation. Yog li ntawd, nws yog ib qho tseem ceeb rau kev ntsuam xyuas cov cuab yeej antioxidant ntawm xws li txheej.

Ntau cov txheej txheem tuaj yeem siv los ntsuas cov khoom siv antioxidant ntawm Boron Nitride txheej. Qhov yooj yim tshaj plaws thiab feem ntau ntawm txhua txoj kev yog Salt Spray Chamber test. Qhov kev sim no tuaj yeem ua tiav raws li tus qauv ASTM B117. Hauv qhov kev sim no, tus qauv coated nrog Boron Nitride raug rau aerosol sib tov ntawm ntsev thiab dej ntawm qhov ntsuas kub thiab av noo rau lub sijhawm tshwj xeeb. Qhov kev cuam tshuam no ua rau kev tsim cov oxide txheej, thiab lub sijhawm siv rau kev tsim cov txheej txheem yog ib qho kev ntsuas ntawm cov cuab yeej antioxidant ntawm txheej. Ntev ntev lub txheej tuaj yeem tiv taus cov txheej txheem oxidation, qhov siab dua yuav yog cov cuab yeej antioxidant.

Lwm txoj hauv kev siv los ntsuas cov khoom siv antioxidant ntawm Boron Nitride Coatings yog TGA (Thermogravimetric Analysis). Hauv qhov kev sim no, cov qauv yog rhuab nyob rau hauv ib qho chaw tswj, thiab tus nqi ntawm qhov hnyav yog saib xyuas. Qhov kub ntawm qhov poob phaus pib thiab xaus yog sau tseg, thiab qhov no yog siv los txheeb xyuas cov thermal stability thiab oxidation tus cwj pwm ntawm txheej. Qhov siab dua qhov kub ntawm qhov oxidation tshwm sim, qhov zoo dua yog cov cuab yeej antioxidant.

Tsis tas li ntawd, qhov kev xeem Outgassing kuj tuaj yeem siv los kuaj tus cwj pwm antioxidant ntawm Boron Nitride coatings. Hauv qhov kev sim no, tus qauv raug rau qhov kub thiab txias, uas ua rau kev tso tawm cov pa roj hauv cov txheej. Cov pa roj no tau txheeb xyuas siv Mass Spectroscopy, thiab kuaj pom muaj cov pa oxygen thiab lwm yam oxidizing gases. Lub xub ntiag ntawm cov pa roj carbon monoxide nyob rau hauv qis qis yog qhov qhia txog cov khoom muaj txiaj ntsig zoo antioxidant.

Hauv kev xaus, cov cuab yeej antioxidant ntawm Boron Nitride coatings yog ib qho tseem ceeb uas yuav tsum tau kuaj ua ntej lawv siv rau hauv txhua daim ntawv thov. Salt Spray Chamber, TGA, thiab Outgassing tests yog qee qhov kev siv ntau tshaj plaws los kuaj cov kab mob antioxidant ntawm cov txheej txheem no. Kev soj ntsuam zoo ntawm cov kev tshawb pom tau los ntawm cov kev sim no tuaj yeem pab txheeb xyuas qhov ua tau zoo thiab ua haujlwm ntev ntawm Boron Nitride coatings.

Shengyang New Material Co., Ltd. tau cog lus rau kev tsim cov boron nitride thiab boron nitride ua cov khoom, thiab tuaj yeem kho ntau yam boron nitride insulating ceramic qhov chaw raws li cov neeg siv khoom xav tau. Tiv tauj peb yog tias tsim nyog.
