Cov nkoj evaporation ua haujlwm li cas

Cov nkoj evaporation yog cov khoom siv ceramic uas ua haujlwm rau cov hlau (ntshiab aluminium) kom evaporated. Lawv ua hauj lwm raws li hluav taws xob tiv thaiv cua sov lub nkoj evaporation thiab ib tug txuas ntxiv noj txhuas hlau yog rhuab nyob rau hauv siab nqus los ntawm tam sim no ntws, kom cov hlau ua ntej melts thiab ces evaporates. Vim qhov tshwj xeeb nto structuring thiab kev ntxhib los mos, ib tug molten da dej yog tsim thiab optimally faib tshaj lub nkoj, yog li xyuas kom meej ib homogeneous huab vapor. Cov hlau vapor ces muab tso rau ntawm lub substrate nyob saum huab cua vapor.

Cov khoom siv rau cov nkoj evaporation

Muaj ntau yam kev xav tau uas cov nkoj evaporation yuav tsum tau ua raws. Rau lub hauv paus ntsiab lus ntawm kev tiv thaiv cua sov ua hauj lwm, lawv yuav tsum tau hluav taws xob conductive; Nyob rau tib lub sijhawm, lawv xav tau qhov siab txaus ntawm hluav taws xob tiv thaiv kom sov lawv ua tau txhua yam. Tsis tas li ntawd, lawv yuav tsum tiv taus kub thiab inert rau molten hlau. Txhawm rau muab cov khoom no, cov ceramics sib xyaw yog tsim los ntawm ob lossis peb yam khoom.

Ob lub nkoj evaporation muaj titanium diboride thiab BORON NITRIDE. Vim nws cov qauv kev sib txuas, titanium diboride muaj kev tiv thaiv zoo rau qhov kub thiab txias thiab tseem tsis muaj zog txawm tias cov hlau tsis muaj hlau yaj. Nws kuj tseem txhim kho lub wettability ntawm lub nkoj evaporation los ntawm cov kua txhuas thiab ua kom lub cev qhuav dej nrog qhov dav dav. Piv txwv li, thaum siv rau txhuas vapor deposition, nws yog kiag li wetted los ntawm cov kua txhuas. Tsis tas li ntawd, titanium diboride yog cov khoom siv hluav taws xob zoo heev. Boron nitride yog ntxiv raws li cov khoom siv tsis yog siv los teeb tsa hluav taws xob tiv thaiv ntawm lub nkoj evaporation.

Peb-cov khoom sib xyaw ceramics kuj suav nrog txhuas nitride. Cov khoom no muaj cov thermal conductivity zoo heev uas ua rau nws tshwj xeeb tshaj yog haum rau cov nkoj loj evaporation kom ntseeg tau tias lawv tuaj yeem ua kom sov sai thiab sib npaug. Piv nrog rau ob lub nkoj evaporation, peb-cov khoom sib xyaw ua ke muaj lub neej luv dua, nrog qis dua evaporation tus nqi thiab tsawg dua corrosion kuj. Nyob rau tib lub sij hawm, lub wettability ntawm evaporator yog ho txhim kho thiab muaj ntau dua homogeneity ntawm vapor-deposited txheej. Peb cov evaporators yog vim li no feem ntau yog siv rau hauv kev tsim cov capacitors, vim qhov no yuav tsum muaj qhov tshwj xeeb siab ntawm homogeneity hauv cov txheej.
