Khoom Qhia
Nqe lus piav qhia:
Silicon nitride ceramics yog superior rau lwm cov ntaub ntawv vim nws thermal shock kuj. Nws tsis deteriorate nyob rau hauv qhov kub thiab txias, yog li nws yog siv rau automotive xyaw thiab qhov chaw rau roj turbines, nrog rau cov turbocharger rotor.
Ortech muab tag nrho tsev neeg ntawm Silicon Nitride cov ntaub ntawv. Cov ntaub ntawv no muaj cov yam ntxwv tseem ceeb hauv qab no: Tsis muaj nplaum hnav tiv thaiv hlau, Ob zaug nyuaj li cov cuab yeej hlau, Cov tshuaj tiv thaiv zoo thiab 60% tsawg dua cov hlau.
Silicon nitrides (Si3N4) yog cov khoom siv hluav taws xob siab tshaj plaws uas muaj lub zog siab, tawv thiab tawv thiab zoo heev tshuaj lom neeg thiab thermal stability.
Silicon nitride tau pom nyob rau hauv nruab nrab-caij xyoo pua, tab sis tsis tau qiv nws tus kheej kom yooj yim ntawm fabrication, vim nws cov kev sib raug zoo sib raug zoo. Qhov no pib ua rau kev txhim kho ntawm ob hom silicon nitride, tshuaj tiv thaiv-bonded silicon nitride (RBSN) thiab kub nias silicon nitride (HPSN). Tom qab ntawd, txij li xyoo 1970s ob hom ntxiv tau tsim: sintered silicon nitride (SSN), uas suav nrog sialons, thiab sintered cov tshuaj tiv thaiv-bonded silicon nitride (SRBSN).
Qhov kev txaus siab tam sim no ntawm silicon nitride raws li engineering cov ntaub ntawv tseem ceeb tau tsim los ntawm kev tshawb fawb hauv xyoo 1980s rau hauv cov khoom siv ceramic rau roj turbine thiab piston xyaw. Nws tau pom tias lub cav, feem ntau yog ua los ntawm silicon nitride raws li qhov chaw, xws li sialon, yuav yog lub teeb yuag thiab muaj peev xwm ua haujlwm ntawm qhov kub siab dua li cov cav qub uas ua rau muaj kev ua tau zoo dua. Thaum kawg, txawm li cas los xij, lub hom phiaj no tsis tau pom zoo los ntawm ntau yam xws li tus nqi, qhov nyuaj ntawm kev txhim kho cov khoom thiab cov yam ntxwv ntawm cov khoom siv ceramics.
Txawm li cas los xij, txoj haujlwm no tau coj mus rau kev txhim kho ntawm ntau lwm cov ntawv thov kev lag luam rau cov khoom siv silicon nitride, xws li hauv kev tsim hlau, kev lag luam hnav thiab molten hlau tuav.
Qhov sib txawv ntawm silicon nitride, RBSN, HPSN, SRBSN thiab SSN, tshwm sim los ntawm lawv txoj kev tsim, uas tswj hwm lawv cov txiaj ntsig thiab kev siv.
