Qhov kev tiv taus oxidation ntawm cov khoom siv ceramic precision yog dab tsi? Qhov no tseem ceeb heev rau hauv qhov xwm txheej twg?

Kev tsis kam ntawm oxidation ntawm cov khoom siv ceramic precision thiab nws qhov chaw siv
Cov khoom siv ceramic precision yog cov khoom siv ua tau zoo tshaj plaws hauv kev lag luam niaj hnub no, thiab lawv cov khoom siv lub cev thiab tshuaj lom neeg tshwj xeeb tau coj kev hloov pauv tshiab rau ntau qhov chaw. Ntawm lawv, kev tiv taus oxidation yog ib qho ntawm cov yam ntxwv tseem ceeb tshaj plaws ntawm cov khoom siv ceramic precision, uas yog qhov tseem ceeb tshwj xeeb hauv qhov chaw ib puag ncig hnyav.
Kev tsis kam oxidation ntawm cov khoom siv ceramic precision
Cov khoom siv ceramic precision, xws li alumina, silicon nitride, silicon carbide, thiab lwm yam, paub txog lawv cov khoom zoo heev antioxidant. Cov ntaub ntawv no tuaj yeem tswj tau cov tshuaj lom neeg ruaj khov nyob rau hauv qhov kub thiab txias siab thiab qhov chaw oxidation siab, thiab tsis yooj yim rau kev cuam tshuam nrog oxygen, yog li zam kev oxidation, corrosion thiab kev ua haujlwm poob qis ntawm cov khoom. Qhov kev tiv thaiv oxidation zoo heev no feem ntau yog vim cov qauv siv lead ua ruaj khov thiab lub zog ntawm cov tshuaj sib txuas hauv cov khoom siv ceramic, uas ua rau nws muaj peev xwm tswj tau lub sijhawm ntev thiab kev ntseeg siab hauv qhov chaw nyuaj.

1. Kev Tsim Kho Dav Hlau
Hauv kev lag luam aerospace, qhov tsis kam ntawm cov khoom siv ceramic precision yog qhov tseem ceeb heev. Cov cav dav hlau thiab cov dav hlau spacecraft yuav tsum tiv taus qhov kub thiab txias heev thiab cov pa oxidizing thaum lub sijhawm ya ceev. Cov khoom xws li cov chav sib xyaw, cov nozzles thiab turbines ua los ntawm cov khoom siv ceramic precision tuaj yeem tswj tau qhov ua tau zoo ntawm qhov kub thiab txias, tiv thaiv kev oxidation thiab corrosion, thiab xyuas kom meej tias lub cav thiab spacecraft ua haujlwm ib txwm.
2. Kev lag luam hluav taws xob
Hauv kev lag luam ntawm lub zog, qhov kev tiv thaiv oxidation ntawm cov khoom siv ceramic precision kuj ua lub luag haujlwm tseem ceeb. Piv txwv li, hauv cov khoom siv kub siab xws li cov roj turbines thiab cov thee-fired boilers, cov khoom xws li cov txheej rwb thaiv tsev thermal thiab cov lim dej ua los ntawm cov khoom siv ceramic tuaj yeem tiv taus kev yaig ntawm cov pa luam yeeb kub siab, tiv thaiv cov qauv sab hauv ntawm cov khoom siv thiab txhim kho kev siv hluav taws xob. Tsis tas li ntawd, hauv kev lag luam ntawm lub zog nuclear, cov khoom siv ceramic precision kuj tseem siv dav hauv cov txheej rwb thaiv tsev thermal thiab txheej tiv thaiv ntawm cov reactors nuclear kom ntseeg tau tias kev siv lub zog nuclear muaj kev nyab xeeb.
3. Kev lag luam tshuaj lom neeg
Hauv kev lag luam tshuaj lom neeg, ntau yam tshuaj lom neeg thiab cov txheej txheem yuav tsum tau ua nyob rau hauv qhov kub thiab txias, siab siab thiab muaj zog corrosive ib puag ncig. Precision ceramic Cheebtsam, nrog lawv cov oxidation zoo heev thiab corrosion tsis kam, yog cov khoom tseem ceeb hauv cov ib puag ncig no. Piv txwv li, hauv cov khoom siv tshuaj lom neeg nrog acid thiab alkali corrosion hnyav, cov khoom xws li cov kav dej, li qub thiab twj tso kua mis ua los ntawm cov khoom siv ceramic tuaj yeem tiv thaiv corrosion thiab to, kom ntseeg tau tias muaj kev nyab xeeb thiab ruaj khov ntawm kev tsim tshuaj.
