GeneralTsananguro yeMaitiroAkasungwa sic
Reaction yakarongedzwa sic ine michina yezvivakwa uye oxidation kuramba. Mutengo wayo wakadzika. Munharaunda yaripo, inokwezva zvakanyanya uye nekuwedzera kwezviitiko mumaindasitiri akasiyana siyana.
SIC ndeye yakasimba kwazvo covent chisungo. Mukuchinjisa, iyo yakashata mwero yakaderera kwazvo. Panguva imwecheteyo, pamusoro pezvikamu zvevakangoita zvinovhara nzvimbo yakatetepa yehusiku iyo inotakura basa rezvishamiso. SIC yakachena haina kutenderwa uye compact pasina kutadza zvinowedzera. Kunyangwe kana maitiro ekutsvina anopisa-anopisa anoshandiswa, inofanirawo kusarudza yakakodzera yekuwedzera. PAMWE chete kupisa kwakanyanya, kunogona zvekushandisa zvakakodzera density density padhuze neiyo density inowanikwa iyo inofanirwa kunge iri mumhando kubva muna 1950】 kusvika ku28】. Kunyangwe manyorerwo ikagona kuwanikwa nemupovhe anogadzwa, inogumira kugadzirira yakaderera density kana zvinhu zvakaonda. Nekuda kwenguva yayo refu yakanyarara, mutengo wekugadzira uchawedzera.
Kuita kwakasungwa SIC kwakagadzirwa muna1950s ne popper. Nheyo yekutanga ndeye:
Pasi pechiito cheCapillary Simba, Liquidon kana Silicon Alloy nebasa rezvikamu zvakapinda muzvikamu zvepusoro zvine kabhoni uye yakaumbwa carbon silicon mukuita. Iyo ichangobva kuumbwa silicon carbide inosungirwa kune yekutanga silicon cardide muStu, uye iyo yakasara pores mu filler inozadzwa nemumiriri wekuzadzisa maitiro ekuzadzisa densation.
Kuenzaniswa nedzimwe nzira dzeSilicon Carbide Ceramics, maitiro ekuchinjisa ane hunhu hunotevera:
Kuderera kwekushongedza tembiricha, kwenguva pfupi yekugadzirisa, hapana chinodiwa chemidziyo yakakosha kana inodhura;
Maitiro akasungwa zvikamu zvisina kuderera kana kuchinja kwehukuru;
Diikaiti dzakasarudzika nzira dzekuumbwa (Extrussion, jekiseni, kudzvanya uye kudururira).
Kune dzimwe nzira dzekuveza. Panguva yekuchinjisa, kukura kwakakura uye zvigadzirwa zvakaoma zvinogona kugadzirwa pasina kudzvanywa. Kuita kwakasarudzika tekinoroji yeSilicon Carbide yakadzidzwa kwehafu yezana. Iyi tekinoroji yave imwe yeanotarisa maindasitiri akasiyana siyana nekuda kwezvakanaka zvaakaita.
