Mumunda weMetallurgy, nhoroondo yekugadzira yeSilicon carbide inowanzoitika yekusvina isiri-ferus simbi inogona kudzoserwa kumashure kuma1930s. Maitiro ayo akaomarara anosanganisira mbichana zvinhu zvinopwanya, kuraswa, ruoko rukova kana roll inoumba, kuomesa, kupfura, kuodza uye unyoro-kuratidzira. Zvinosanganiswa zvinoshandiswa zvinosanganisira graphite, ivhu, pyrophyllite clinker kana yepamusoro-alumina bauxite clinker, monoslica poda kana ferrosilica poda nemvura, yakasanganiswa mune imwe chikamu. Nekufamba kwenguva, silicon carbide yakabatanidzwa kuti ishandise iyo inobata yekuisa uye kugadzirisa hunhu. Nekudaro, iyi nzira yechinyakare ine yakakwirira simba rekushandisa, refu kugadzirwa kutenderera, uye kurasikirwa kukuru uye deformation mune imwe-yakapedza chigadzirwa chigadzirwa.
Mukupesana, nhasi ramangwana rakanyanya kujairika rekugadzira maitiro anoenderana nekumanikidza. Iyi tekinoroji inoshandisa graphite-silicon carbide inowanzoitika, ne phenool resin, tar kana asphalt seyemumiriri anosunga, uye graphite uye silicon carbide seyakavhurwa. Iyo inokonzerwa nekukonzeresa ine porosity yakaderera, yakanyanya density, yunifomu yekugadzirisa uye yakasimba kupesana. Pasinei nezvakanaka izvi, maitiro ekusimbisa anoburitsa utsi hunokuvadza neguruva, zvichikonzera kusvibiswa kwezvakatipoteredza.
Iko kushanduka kweSilicon Cardide kugadzirwa kwechibereki kunoratidza kuenderera mberi kwekutsvaga kweindasitiri kwekubudirira, mhando uye mutoro wemunharaunda uye mutoro wezvakatipoteredza. Semunhu tekinoroji inofambira mberi, iyo inotarisisa iri kukudziridza nzira dzekudzora simba rekushandisa simba, kupfupisa mitezo yekugadzira uye kuderedza mamiriro ekunze. Vagadziri vanoongorora vari kuongorora zvigadzirwa zvine mutsindo uye maitiro kuti uwane izvi zvinangwa, chinangwa chekurova chiyero pakati petsika uye chazvino. Sezvineiwo nekusvirwa kusiri-simbi simbi kunoramba kuchikura, kuitika mukugadzirwa kunoenderana kuchaita basa rakakosha mukuumba ramangwana reMetallurgy.
