Tungsten Evaporation Nkoj Thiab Boron Nitride Evaporation Nkoj

Thaum nws los txog rau fabrication ntawm nyias zaj duab xis rau ntau yam kev siv, kev xaiv ntawm evaporation nkoj plays lub luag haujlwm tseem ceeb hauv cov txheej txheem. Ob lub nkoj uas nquag siv yog tungsten thiab boron nitride nkoj. Hauv tsab xov xwm no, peb yuav tshawb txog qhov sib txawv ntawm tungsten evaporation nkoj thiabboron nitride evaporation nkojthiab lawv qhov zoo.

Tungsten evaporation nkoj yog tsim los ntawm tungsten hlau. Lawv paub txog lawv qhov siab melting point, uas ua rau lawv zoo tagnrho rau siv nyob rau hauv high-temperature nqus cov ntaub ntawv. Tungsten kuj tseem tiv taus thermal shock, uas txhais tau hais tias nws tuaj yeem tiv taus qhov kub thiab txias hloov tsis tau tawg lossis tawg. Tsis tas li ntawd, cov nkoj tungsten muaj cov coefficient tsawg ntawm thermal expansion, uas txhais tau hais tias lawv yuav tsis deform lossis warp thaum lub sij hawm cua sov thiab cua txias. Cov khoom no ua rau cov nkoj tungsten zoo tagnrho rau siv hauv kev tsim cov hlau, alloys, thiab ceramics.

Ntawm qhov tod tes, boron nitride evaporation nkoj yog tsim los ntawm cov khoom siv ceramic. Boron nitride yog cov khoom siv ua haujlwm siab nrog cov thermal conductivity zoo, kub-kub stability, thiab tshuaj inertness. Nws muaj cov coefficient tsawg heev ntawm thermal expansion, uas txhais tau tias nws yuav tsis deform thaum lub sij hawm cua sov thiab cua txias mus. Boron nitride tej nkoj nquam yog zoo tagnrho rau siv nyob rau hauv fabrication ntawm hlau, alloys, thiab lwm yam reactive ntaub ntawv uas yuav tsum tau ib tug chemically inert ib puag ncig.

Piv rau tungsten nkoj, boron nitride nkoj muaj ntau yam zoo. Ua ntej thiab qhov tseem ceeb tshaj plaws, cov nkoj boron nitride yog cov tshuaj inert, uas txhais tau tias lawv tsis hnov ​​​​mob nrog cov ntaub ntawv raug evaporated. Qhov no yog ib qho tseem ceeb tshwj xeeb tshaj yog thaum ua hauj lwm nrog reactive hlau los yog hlau alloys, vim hais tias cov nkoj yuav tsis paug cov nyias films. Tsis tas li ntawd, cov nkoj boron nitride muaj qhov tshwj xeeb thermal poob siab, ua rau lawv zoo tagnrho rau kev siv hauv cov txheej txheem nqus tsev kub.

Hauv cov ntsiab lus, ob lub nkoj tungsten thiab boron nitride evaporation yog qhov muaj txiaj ntsig zoo rau kev tsim cov yeeb yaj kiab nyias. Qhov kev xaiv feem ntau yog nyob ntawm daim ntawv thov tshwj xeeb thiab cov khoom raug evaporated. tungsten nkoj yog qhov zoo tagnrho rau cov txheej txheem nqus cua kub thiab cov khoom siv uas yuav tsum tau ua kom muaj cua sov siab. Boron nitride tej nkoj nquam, ntawm qhov tod tes, muaj cov tshuaj tiv thaiv zoo heev thiab thermal poob siab, ua rau lawv zoo tagnrho rau siv nrog cov ntaub ntawv reactive.
