Chubhu yekudzivirira yeRBSiC
Ruzivo rweChigadzirwa
Machubhu ekudzivirira eSilicon carbidezvinhu zvakakosha zvemachubhu zvakagadzirwa nezvinhu zve silicon carbide (SiC) ceramic, zvinonyanya kushandiswa kuchengetedza zvinhu zvinonzwa (zvakadai se thermocouples) kana sezvikamu zvikuru mumidziyo yekufambisa mvura inopisa uye yekuchinjana kupisa.
Zvigadzirwa zvedu zvinogadzirwa zvakanyanya uchishandisa maitiro matatu:Kupisa kwemaitiro (RBSiC), Kugadziriswazve kwekristalo (RSiC), Silicon nitride yakasungirirwa silicon carbide (NSiC)
1. Machubhu ekudzivirira eRBSiC
Zvichishandisa SiC particles ne graphite sezvinhu zvakagadziriswa, zvinhu izvi zvinopinda mu silicon infiltration process. Liquid silicon inopinda mu pores, ichibatana ne graphite kuti igadzire SiC phase itsva, zvichizogadzira chimiro chakabatana che "SiC framework + free silicon".
Hunhu Hukuru:
Kuwanda kwakanyanya uye kuderera kwekuyerera kwemvura:Silikoni yemahara inozadza maburi, ichideredza maburi kusvika pasi pe1%, zvichiita kuti mhepo isapinde zvakanaka uye isapindike zvakanyanya, yakakodzera kushandiswa pakupisa kwakanyanya uye kupisa kwakanyanya.
mamiriro ekuvhara (senge machoto anopisira simba).
Hunhu hwakanaka hwemakanika:Simba rekuchinjika kwemukamuri rinosvika 250–400MPa, kusimba kwekutsemuka kwakanyanya, uye kuramba kusimba kwesimbi kupfuura silicon carbide yakadzokororwa.
Kudzivirira kupisa kwakanyanya zvine mwero:Tembiricha yekushanda kwenguva refu ndeye 1200℃. Pamusoro pe1350℃, silicon yakasununguka inonyorova, zvichikonzera kudzikira kwesimba uye kudzikamisa kushanda kwekupisa kwakanyanya.
Kugona kugadziriswa zvakanaka:Kuvapo kwesilicon yakasununguka kunoderedza kuputsika kwezvinhu, zvichiita kuti zvive nyore kugadzira maumbirwo akaomarara, zvichikonzera mitengo yakaderera yekugadzira.
Miganhu:
Kushanda kwekupisa kwakanyanya kunogumira pakushandiswa kwesilicon yakasununguka, zvichiita kuti isakodzere kushandiswa kwenguva refu pamusoro pe1350℃; silicon yakasununguka inokurumidza kushanda nealkalis yakasimba, aluminium yakanyungudutswa, nezvimwewo, zvichikonzera kuti isakwanise ngura zvakanyanya.
2. Machubhu ekudzivirira eRSiC
Uchishandisa upfu hweSiC micro hwakachena zvakanyanya sezvinhu zvisina kugadzirwa, hunopiswa pakupisa kwakanyanya (2000–2200℃). Chimiro chakasimba chinoumbwa kuburikidza nekusanganiswa kwezvimedu zveSiC pachazvo, pasina imwe nzira yekubatanidza.
Hunhu Hukuru:
Kuramba Kunopisa Zvikuru:Tembiricha yekushanda kwenguva refu inosvika 1600℃, kuramba kwenguva pfupi kusvika 1800℃, zvichiita kuti ive yakanakisa kana tichitarisa kuramba kupisa kwakanyanya pakati pemhando nhatu idzi, yakakodzera makiln anodziya zvakanyanya (senge makiln esimbi anodziya nesimbi uye makiln esimbi anoputika).
Kuramba Kuoxidation Kwakanaka:Pakupisa kwakanyanya, firimu rekudzivirira reSiO₂ rinoumbwa pamusoro, richidzivirira kuwedzera kwe oxidation yemukati meSiC, richiratidza kugadzikana kwakanyanya mumhepo inooxidating.
Kuwanda kweThermal kwakaderera zvikuru:Chiyero chekuwedzera kwekupisa i4.5 × 10⁻⁶ /℃ chete, zvichipa simba rakanaka rekudzivirira kupisa, kunyangwe zvakaderera zvishoma pane zvesilicon nitride-bonded silicon carbide.
Kuomarara kwakanyanya uye kuramba kupfeka kwakanyanya:Nekuomarara kweMohs kuri pedyo ne9, inoratidza kusimba kukuru pakukukurwa kwezvinhu, zvichiita kuti ikodzere kufamba kwemhepo inopisa uye kuyerera kwemvura ine zvidimbu zvakasimba.
Kugadzikana kwakasimba kwemakemikari:Haipindi muacids dzakasimba uye alkalis, uye haipindi musimbi dzakawanda dzakanyungudutswa.
Miganhu:
Kupisa kwakanyanya kwazvo, zvichikonzera kukwira zvishoma kwehuremu (inenge 5%–8%) uye kusimba kwesimba repamusoro-soro; kusimba kwakanyanya kwekupisa kwemukamuri, uye kusimba kwesimba hazvina kunaka sesilicon carbide ine silicon nitride.
3. Chubhu yekudzivirira yeNSiC
Chinhu chakabatanidzwa chinoumbwa nekubatanidza zvakasimba zvidimbu zveSiC musilicon carbide matrix nekugadzira Si₃N₄ sechikamu chinosunga kuburikidza ne nitriding reaction.
Zvinhu Zvikuru:
1. Kuramba Kupisa Kwekupisa Kwakanyanya:Kuwanda kwekupisa kwakaderera uye kusimba kwakanyanya kwechikamu chakabatanidzwa cheSi₃N₄ kunoita kuti chubhu inodzivirira ikwanise kutsungirira kupisa nekutonhora nekukurumidza pamusoro pe1000℃ isina kutsemuka nekuda kwekuchinja kwekushisa kamwe kamwe, zvichiita kuti ive yakakodzera mamiriro ekushanda ane kushanduka-shanduka kwekupisa kakawanda.
2. Kuramba Kura Kwakanaka Kwazvo:Yakasimba zvikuru pakurwisa maasidhi akasimba, maalkali akasimba, simbi dzakanyungudutswa (dzakadai searuminiyamu nemhangura), uye munyu wakanyungudutswa, zvichiita kuti ive yakakodzera zvakanyanya munzvimbo dzinopisa mumaindasitiri emakemikari nesimbi.
3. Simba reMichina Rakanyanya:Simba rekuchinjika kwemukamuri rinosvika 300–500 MPa, richichengetedza simba zviri nani pakupisa kwakanyanya kupfuura zvigadzirwa zveSiC yakachena, uye rinodzivirira kukuvadzwa kwakasimba.
4. Kupisa Kunoshanda:Tembiricha yekushanda kwenguva refu 1350℃, kugona kwenguva pfupi kutsungirira kusvika 1500℃.
5. Kudzivirira Kwakanaka:Inochengetedza kuvharwa kwemagetsi kwakanaka kunyangwe pakupisa kwakanyanya, ichidzivirira kukanganiswa kwechiratidzo che thermocouple.
Miganhu:
Kuramba kuoxidation kwakaderera zvishoma pane silicon carbide yakadzokororwa; kushandiswa kwenguva refu munzvimbo dzine oxidizing yakasimba kunogona kukonzera kudonha kweganda repamusoro pe oxide layer.
