Rau Nitride ua ke Silicon Carbide s, lawv cov khoom ua ntej yuav zoo li thermal poob siab thiab siab kub creep kuj. Silicon carbide muaj cov thermal conductivity zoo, thaum silicon nitride muaj cov thermal expansion tsawg. Thaum ob leeg muaj kev sib xyaw ua ke los ua ib qho Nitride bonded Silicon Carbide , cov khoom ua tau zoo thermal poob siab.
Yog hais tias qhov loj me me thaum lub sij hawm kub thiab txias txias, thaum lub ntsuas kub txias li ntawm 1300 ° C mus rau 20 ° C, nws yuav siv sij hawm ntau pua cua kub cua, tab sis qhov no yuav tsis ua rau cov khoom siv thiab ua kom tsawg lub sij hawm tua hluav taws. Tsis tas li ntawd, nyob rau hauv kev tsim cov txheej txheem ntawm Nitride ua ke Silicon Carbide s, qhov sib txawv me ntsis yog tsawg tshaj li 1%, thiab vim tsis muaj iav theem, cov khoom tsis tshuam deformed nyob rau hauv high school tej yam kev mob, yog li ntawd lub deformation ntawm pov tseg khoom thiab cov khoom tseem yuav tsis tshwm sim.
Secondly, Nitride bonded Silicon Carbide s kuj tau zoo oxidation kuj, hnav ua haujlwm thiab corrosion kuj. Lub microhardness ntawm silicon carbide thiab silicon nitride yog ib qho me me piv rau cov khoom xws li boron carbide, cubic boron nitride, thiab pob zeb diamond, thiab silicon nitride muaj ib qho coefficient ntawm kev sib txhuam thiab kev tswj tus kheej zoo. Yog li, Nitride bonded Silicon Carbide muaj cov tshuaj lom neeg zoo, tuaj yeem feem ntau ntawm alkali corrosion thiab inorganic acid corrosion, muaj oxidation kuj zoo tuaj, tuaj yeem tawm tsam cov hmoov txhuas txhuas thiab aluminium alloy yaj, thiab cov hlau non-ferrous Erosion, kub qhov taw qhia rwb thaiv tsev zoo yog qhov zoo.
Nitride bonded Silicon Carbide s muaj zog zuj zus yooj yim tshaj li av nplaum silicon carbide khoom, thiab lawv cov chav nyob hauv cov khoom kub qhov ob lub zog yog ob zaug uas cov av nplaum silicon carbide khoom. Yog tias cov txheej txheem tsis muaj teeb meem, cov chav nyob hauv chav nyob yog nyob ntawm 1200 ° C mus txog 1400 ° C, thiab lub zog ntawm cov khoom siv tiv thaiv hnyav tuaj ntxiv rau 9 npaug ntawm qhov av nplaum silicon carbide product.www.hshightec .com
