Hauv thaj chaw loj ntawm cov ntaub ntawv science,cov khoom siv silicon carbidemaj mam dhau los ua "darling" ntawm ntau lub lag luam vim lawv cov khoom tshwj xeeb. Tshwj xeeb tshaj yog nws zoo heev hnav kuj ua rau nws ci nyob rau hauv ntau yam kev siv. Niaj hnub no, cia peb delve rau hauv kev hnav tsis kam ntawm silicon carbide khoom ua ke.
Silicon carbide, los ntawm cov tshuaj muaj pes tsawg leeg foundations, yog ib qho kev sib xyaw ua ke los ntawm ob lub ntsiab lus, silicon thiab carbon, ntawm qhov kub thiab txias. Nws cov qauv siv lead ua yog qhov tshwj xeeb heev, uas tso cai rau silicon carbide nrog cov khoom zoo heev, thiab qhov nyuaj siab yog lub hauv paus tseem ceeb rau nws hnav tsis kam. Lub hardness ntawm silicon carbide yog heev siab, nrog ib tug Mohs hardness ntawm ib ncig ntawm 9.5, tsuas yog me ntsis inferior rau lub hardest pob zeb diamond nyob rau hauv cov xwm. Cov tawv tawv zoo li no txhais tau hais tias nws tuaj yeem tiv thaiv kev sib txhuam sab nraud thiab hnav, thiab tseem tuav nws txoj kev ncaj ncees thiab kev ua haujlwm ruaj khov nyob rau hauv lub ntsej muag ntawm ntau yam kev siv hnyav.
Los ntawm qhov kev xav ntawm microscopic, microstructure ntawm silicon carbide cov khoom yog tuab heev. Yuav luag tsis muaj qhov pores loj lossis qhov tsis xws luag hauv, uas ua rau nws tsis tshua muaj kev puas tsuaj ntawm cov khoom thiab cov khoom siv thaum raug kev sib txhuam. Nws zoo li lub tsev fuabtais ruaj khov, nrog cov phab ntsa txuas nrog nruj uas nyuaj rau cov yeeb ncuab tawg. Thaum muaj kev sib txhuam ntawm cov khoom sab nraud thiab qhov chaw ntawm silicon carbide, nws cov qauv ntom ntom tuaj yeem cuam tshuam cov kev sib txhuam quab yuam, zam kev hnav hauv zos los ntawm kev ntxhov siab, thiab txhim kho tag nrho cov hnav tsis kam.
Kev ruaj ntseg tshuaj kuj yog ib qho cuab yeej tseem ceeb rau kev hnav tsis kam ntawm silicon carbide. Hauv ntau qhov xwm txheej siv tau, cov khoom siv tsis yog tsuas yog yuav tsum tau tiv thaiv kev siv tshuab, tab sis kuj tuaj yeem ntsib cov tshuaj yaig. Silicon carbide muaj tshuaj lom neeg ruaj khov zoo, thiab nws tsis yooj yim rau cov tshuaj tiv thaiv nrog lwm yam tshuaj uas tuaj yeem ua rau kev ua haujlwm tsis zoo, txawm tias nyob rau hauv ib puag ncig corrosive chemical lossis nyob rau hauv huab cua txias xws li kub. Txawm tias nyob rau hauv qhov hnyav ntawm qhov kub thiab txias thiab corrosion mus ntev, cov khoom siv silicon carbide tseem tuaj yeem tuav lawv cov hardness thiab cov qauv kev ncaj ncees, thiab txuas ntxiv ua kom pom kev hnav zoo.
Hauv kev siv tswv yim, qhov hnav tsis kam zoo ntawm cov khoom siv silicon carbide tau ua kom pom tseeb. Hauv kev lag luam mining, silicon carbide feem ntau yog siv los tsim cov cuab yeej mining xws li laum cov khoom, cov cuab yeej txiav, thiab lwm yam. Cov cuab yeej no yuav tsum tau tiv taus cov neeg kho tshuab kev ntxhov siab thiab kev sib txhuam tsis tu ncua thaum lub sij hawm cov txheej txheem mining hard ores, thaum silicon carbide, nrog rau nws cov hnav tsis kam, muaj peev xwm txuas tau lub neej kev pab cuam ntawm cov cuab yeej, txo cov cuab yeej hloov min zaus. Silicon carbide kuj tau siv dav hauv sealing Cheebtsam, bearings, thiab lwm qhov chaw ntawm kev lag luam machinery. Nws tuaj yeem txo qhov hnav ntawm cov khoom siv no thaum lub sijhawm ua haujlwm siab thiab kev sib txhuam tsis tu ncua, txhim kho kev ua haujlwm zoo thiab ruaj khov ntawm cov khoom siv, thiab txo cov nqi tu.
Kev hnav tsis kam ntawm cov khoom siv silicon carbide yog txiav txim siab los ntawm lawv cov tshuaj muaj pes tsawg leeg, cov qauv siv lead ua, thiab cov yam ntxwv ntawm microscopic. Nrog kev nce qib ntawm kev siv thev naus laus zis thiab kev tshawb fawb tob tob ntawm silicon carbide, peb ntseeg tias cov khoom siv silicon carbide yuav raug siv rau hauv ntau lub teb, coj cov cib fim tshiab thiab kev hloov pauv rau kev txhim kho ntawm ntau yam kev lag luam.
