Bearings thiab li qub yog ob qho kev siv ntau tshaj plaws rau silicon nitride ceramic pob. Kev tsim cov pob silicon nitride siv cov txheej txheem uas ua ke nrog isostatic nias nrog roj siab sintering. Cov khoom siv raw rau cov txheej txheem no yog silicon nitride hmoov zoo nrog rau cov khoom siv sintering xws li txhuas oxide thiab yttrium oxide.
Txhawm rau ua tiav qhov xav tau loj ntawm silicon nitride pob, lub pob zeb diamond log yog siv hauv cov txheej txheem sib tsoo.
Kev nthuav dav ntawm silicon nitride npas kev lag luam feem ntau yog tsav los ntawm cov khoom zoo tshaj ntawm cov khoom no.
Cov pob no yog siv rau hauv cov kabmob, uas tso cai rau ob qhov chaw txav mus rau ib leeg thaum tseem txhawb nqa cov khoom thauj los ntawm ib feem kom nws nyob hauv qhov chaw. Bearings tuaj yeem xav tias yog kev sib koom ua ke ntawm kev sib koom ua ke thiab kev txhawb nqa cov kabmob. Nws muaj qhov ntom ntom tsawg thiab tsawg thermal nthuav tawm ntxiv rau muaj lub siab tiv taus qhov cuam tshuam ntawm thermal poob siab. Ntxiv rau qhov no, nws lub zog tsis cuam tshuam los ntawm qhov kub txog li ib txhiab degrees Celsius. Silicon nitride npas yog siv nyob rau hauv lub tshuab cuab tam spindles, kho hniav xyaum, kev sib tw lub cev muaj zog, aerospace, kev kub ceev cua turbine bearings, thiab biotechnology industries rau siab kub thiab siab ceev daim ntaub ntawv, feem.
Silicon nitride valve npas muab cov qauv kev ua haujlwm tsim nyog rau kev lag luam ntawm kev tshawb nrhiav roj thiab rov qab. Nws tseem yog tshuaj inert, muaj lub zog siab, thiab muaj kev tiv thaiv zoo heev rau kev puas tsuaj thiab corrosion. Tsis tas li ntawd, nws yog ib qho khoom siv hnyav. Nws muaj peev xwm tiv taus qhov kub thiab txias uas tam sim no nyob rau hauv cov dej sib sib zog nqus ua tsaug rau nws cov thermal shock tsis kam thiab nws cov coefficient tsawg ntawm thermal expansion.
Yog li ntawd, qhov nce hauv kev tshawb nrhiav roj thiab roj ua haujlwm tau ua lub zog tsav tom qab kev nthuav dav ntawm kev lag luam thaum lub sij hawm them los ntawm kev kwv yees. Qhov sib txawv tseem ceeb ntawm tus nqi ntawm silicon nitride pob bearings thiab steel pob bearings yog qhov tseem ceeb ua haujlwm tiv thaiv kev nthuav dav ntawm kev lag luam. Nws tau cia siab tias cov cib fim tshiab yuav dhau los muaj rau cov neeg ua si hauv kev ua lag luam vim tias muaj kev nce ntxiv hauv kev siv cov khoom siv silicon nitride hauv ntau qhov kev lag luam siv kawg, suav nrog cov tsheb, aerospace, kev kho mob, thiab tshuaj lom neeg, ntawm lwm tus.
