Siab hardness thiab siab zog
Lub hardness ntawm silicon nitride ntawm mohs nplai ncav cuag 9 thiab saum toj no, thiab lub hardness} hv, uas yog ze rau cov khoom tawv ntawm qee cov ntaub ntawv superhard. Lub zog compressive ntawm silicon nitride kuj yog siab heev, feem ntau ncav ntau dua 1 GPA, cia nws ua kom pom kev zoo hnav thiab cuam tshuam rau hauv cov khoom siv tshuab. Hauv ntau qhov kev kub ceev thiab siab dua qub, cov kev pabcuam lub neej ntawm silicon nitride seem yog qhov yooj yim los hnav lossis tawg tshwj xeeb, uas yog qhov tsim nyog rau cov khoom tseem ceeb uas yuav tsum tau nyob ruaj khov rau lub sijhawm ntev.
Txhais tau tias zoo heev
Tause Hydraulic tawv yog qhov muaj peev xwm ntawm cov khoom siv kom tiv taus pob txha lossis chaw thau khoom nrawm. Cov ntaub ntawv sib xyaws feem ntau yog nkawv, tab sis cov pob txha lov ntawm silicon nitride mus txog ntawm cov khoom sib xyaw ua ke xws li Alumina (txog 3 MPA-m¹ / ²). Cov xeeb ceem no muab silicon nitride ruaj khov nyob rau hauv cov xwm txheej huab, cia nws tiv thaiv cov khoom zoo rau kev tsim cov cuab yeej thiab cov khoom siv hnyav.
Compressive thiab Flexural
Lub zog lub zog ntawm silicon nitride tuaj yeem ncav cuag 3000mpa, thiab lub zog flexural yog} MPa ntau dua li cov ntaub ntawv ceramic. Kev sib xyaw ua ke ntawm compressive thiab Flexural zog tso cai rau Silicon Nitride nyob rau hauv kev tsim cov kabmob hauv qab, yog li nws muaj cov kabmob thiab lwm yam khoom uas yuav tsum tau tiv thaiv siab. Piv nrog tsoos hlau bearings, silicon nitride bearings tuaj yeem tswj tau kev ua tau zoo thiab muaj kev ua haujlwm hnyav, thiab ncua kev pabcuam lub neej ntawm cov cuab yeej siv.
