Silicon carbide ceramickuumbwa process yekuenzanisa: kutadza maitiro uye zvakanakira uye zvakashata
Mukugadzirwa kweiyo silicon carbide ceramics, kuumbwa inongova imwe chete yekubatanidza mune yese maitiro. Kuchinjisa ndiyo nzira yepakati iyo inokanganisa zvakananga kuita kwekupedzisira uye kuita kwe ceramics. Pane nzira dzakawanda dzakasiyana dzekutadza silicon cardide cardics, imwe neimwe ine zvayo zvakanakira uye zvakaipa. Mune ino blog post, isu tichaongorora maitiro ekutadza weSilicon Cardide carerics carerics uye enzanisa nzira dzakasiyana siyana.
1. Kuita kuchinjisa:
Kuita kwekuchinjisa inzira yakakurumbira maitiro eiyo silicon carbide ceramics. Ichi chiitiko chakareruka uye chinoshanda-chinoshanda padhuze nepakati-kusvika-saizi maitiro. Kuchinjisa kunowanikwa neiyo silicidation reaction pane yekudziya tembiricha ye1450 ~ 1600 ° C uye nguva ipfupi. Iyi nzira inogona kuburitsa zvikamu zvehukuru hwakakura uye chimiro chakaoma. Nekudaro, zvakare zvine zvazvakanganisa. Iyo siliconezitizing maitiro inotungamira kune 8% ~ 12% yemahara silicon muSilicon muchinda, iyo inoderedza michero yakakwira, iyo corrostion kuramba, uye oxidation kuramba. Uye tembiricha yekushandisa inogumira pazasi 1350 ° c.
2. Kupisa kudzvanya kuchinjisa:
Kupisa kutsvuka kuchinjisa ndeimwezve yakajairika nzira yekutadza silicon carbide cardics. Nenzira iyi, yakaoma silicon carbide poda inozadzwa muumbi uye kupisa paunenge uchishandisa kumanikidza kubva kune unixicial nhungamiro. Uku kuhwina kuomeswa uye kudzvanywa kunosimudzira chidimbu chakashata, kuyerera, uye kukonzerwa neSilicon Carbide neZvakakura zvakanaka, huwandu hwakanyanya hwekuwedzera, uye zvakanakisa michina. Nekudaro, kudzvanya kupisa kuchitadzawo kune izvo zvakaringana. Maitiro acho anonyanya kuomesa uye anoda yakakwirira-mhando mold zvinhu nemidziyo. Kubudirira kwekugadzira kwakaderera uye mutengo wakakwira. Uye zvakare, iyi nzira yakakwana chete kune zvigadzirwa zvine maumbirwo akareruka.
3. Hot isostatic kumanikidza kuchinjisa:
Hot Isoostatic Purning (HIP) Kuchinjisa inzira inosanganisira chiitiko chakasanganiswa chekupisa kwakanyanya uye isotropically zvine musoro-kudzvinyirira gasi. Iyo inoshandiswa pakutadza uye inogadziriswa yeSilicon carbide caramic poda, muviri wegirini kana muviri wakambotumirwa. Kunyangwe hip hwokuchinjira inogona kuvandudza mashandiro eSilicon Carbide Ceramics, haina kushandiswa zvakanyanya mukugadzirwa kukuru nekuda kweiyo yakaoma maitiro uye mutengo wakanyanya.
4. Asina simba kutadza:
Asina simba kutadza inzira ine yakanaka kwazvo tembiricha yekushisa, iri nyore kutadza maitiro uye mutengo wakaderera weSilicon Carbide carbide. Izvo zvakare zvinobvumira nzira dzakawanda dzekugadzira, zvichiita kuti zviite zvakakodzera maumbirwo akaoma uye zvikamu zvakakora. Iyi nzira yakakodzera kwazvo kune yakakura-nhanho maindasitiri kugadzirwa kweiyo silicon ceramics.
Mukupfupikisa, maitiro ekutadza chikamu chakakosha mukugadzirwa kweSIC ceramics. Sarudzo yezvinhu zvekutadza zvinoenderana nezvinhu zvakadai sezvinhu zvaunoda zvivakwa zveCeramic, kuomarara kwechimiro, kugadzirwa kwemutengo uye kushanda zvakanaka. Maitiro ega ega ane zvaakaraira uye zvakashata, uye zvakakosha kuti afunge izvi zvinhu kuti uone maitiro akakodzera ekutadza ekutadza kwechimwe chinhu chaicho.
