Cov tshuaj tiv thaiv Bonded Silicon Carbide
Cov khoom sib xyaw ua ke ntawm cov silicon carbide uas tau sib txuas ua ke tau tsim los kom muaj zog thiab tiv taus xeb zoo tshaj plaws. Cov txiaj ntsig ntawm kev siv cov silicon carbide uas tau sib txuas ua ke suav nrog: kev tiv taus hnav zoo heev, lub neej ntev vim nws tiv taus oxidation zoo heev, tiv taus thermal shock zoo heev, thiab muaj peev xwm ua cov duab loj lossis me.
Nitride Bonded Silicon Carbide
Silicon nitride bonded silicon carbide yog tsim los rau kev tiv taus kev hnav zoo heev. Nws tuaj yeem tsim ua cov duab zoo nkauj heev vim nws cov yam ntxwv castable thiab kuj muaj cov khoom refractory thiab tshuaj lom neeg zoo. Nws siv thawj zaug yuav yog qhov twg xav tau kev tiv taus kev hnav siab tshaj plaws lossis qhov twg cov duab nyuaj dhau los ua rau hauv lwm cov khoom sib xyaw. Ob chav hluav taws xob uas muaj qhov qhib porosity tsawg dua thiab txhim kho kev tiv thaiv oxidation kuj muaj.
Sintered Silicon Carbide
Cov sintered alpha silicon carbide yog tsim los ntawm kev sintering ultra-pure submicron hmoov. Cov hmoov no yog sib xyaw nrog cov khoom siv sintering uas tsis yog oxide, tom qab ntawd tsim ua cov duab nyuaj los ntawm ntau txoj kev thiab sib sau ua ke los ntawm kev sintering ntawm qhov kub siab tshaj 3632 ° F.
Cov txheej txheem sintering ua rau muaj ib theem silicon carbide zoo uas yog ntshiab thiab sib xws, tsis muaj porosity ua rau cov ntaub ntawv tiv taus cov chaw corrosive, abrasive ib puag ncig, thiab cov chaw ua haujlwm hauv qab qhov kub siab (2552 ° F). Cov khoom no ua rau sintered alpha silicon carbide zoo tagnrho rau cov ntawv thov xws li cov tshuaj lom neeg thiab cov twj tso kua mis slurry thiab bearings, nozzles, twj tso kua mis thiab valve trim, ntawv thiab textile Cheebtsam, thiab ntau ntxiv.
