Cermets yog siv nyob rau hauv kev tsim cov resistors (tshwj xeeb tshaj yog potentiometers), capacitors, thiab lwm yam hluav taws xob Cheebtsam uas tej zaum yuav muaj kub. Cermets yog siv los hloov tungsten carbide nyob rau hauv saws thiab lwm yam brazed cov cuab yeej vim lawv superior hnav thiab corrosion zog.
Yim hu ua cermet?
A cermet yog cov khoom sib xyaw ua ke ntawm cov khoom siv ceramic suav nrog titanium carbide (TiC), titanium nitride (TiN), thiab titanium carbonitride (TiCN) sib koom nrog hlau. Lub npe "cermet" muab cov lus ceramic (cer) thiab hlau (metal).
YYuav ua li cas cov khoom sib xyaw yog cermets?
A cermet yog cov khoom siv sib xyaw suav nrog ceramic (cer) thiab hlau (metallic) cov ntaub ntawv. Cov ceramic feem ntau muaj qhov kub thiab txias tsis kam, thiab cov hlau muaj peev xwm ua rau cov yas deformation. Lub cermet yog tsim los kom muaj kev sib koom ua ke zoo ntawm cov ceramic thiab hlau.
Cermet ua li cas?
Muaj ntau txoj hauv kev los tsim cov cermets. Ib qho kev xaiv muaj nyob ntawm no. DU dioxide thiab steel hmoov sib tov, qhov sib tov yog muab tso rau ntawm cov nplooj ntawv huv ntawm cov hlau, "sandwich" yog rhuab, thiab cov qhaub cij yog dov. Qhov tshwm sim yog ib qho khoom cermet, uas muaj cov hlau huv sab nrauv.
Qhov txawv ntawm cermet thiab ceramic yog dab tsi?
yog tias ceramic yog (tsis suav tau) cov khoom siv tawv tawv uas tsim tawmlos ntawm kev kub nyhiab ntawm cov khoom siv hlau tsis zoo ntawm qhov kub thiab txias thaum cermet yogcov khoom sib xyaw cov khoom siv los ntawm cov khoom siv ceramic thiab hlau, siv rau hauv cov ntawv thov xws li kev lag luam saws thiab turbine hniav.
