Reaction Bonded Silicon Carbide
Reaction bonded silicon carbide nziyo dzakagadzirirwa kuti dzive dzakanyanya kusimba uye kusadzivirirwa nekuora. Zvakanakira kushandisa reaction bonded silicon carbide zvinosanganisira: kusarudzika kupfeka kuramba, hupenyu hurefu nekuda kwekupokana kwayo neoxidation, yakanakisa yekupisa kuvhunduka kwekurwisa, uye yakakura kana diki yakaoma chimiro kugona.
Nitride Bonded Silicon Carbide
Silicon nitride yakasungirirwa silicon carbide yakagadzirirwa kusarudzika kupfeka kuramba. Inogona kuumbwa kuita yakaomesesa zvimiro nekuda kwehunhu hwayo hwekukandwa uye zvakare ine inodiwa refractory uye makemikari zvimiro. Kunyanya kushandiswa kwayo kuchave uko kunonyanya kupfeka kuramba kunodiwa kana uko chimiro chakanyanya kuomarara kuita mune mamwe masanganiswa. Mavhezheni akadzimwa kaviri ane porosity yakavhurika uye yakagadziridzwa oxidation kuramba iripo zvakare.
Sintered Silicon Carbide
Sintered alpha silicon carbide inogadzirwa ne sintering ultra-pure submicron poda. Iyi poda inosanganiswa nenon-oxide sintering aids, yobva yaumbwa kuita maumbirwo akaomarara nenzira dzakasiyana siyana uye yakasanganiswa nekupisa patembiricha inopfuura 3632°F.
Iyo sintering process inokonzeresa imwe-phase fine-grained silicon carbide iyo yakachena kwazvo uye yakafanana, isina kana porosity inoita kuti zvinhu zvikwanise kumira munzvimbo dzinoita ngura, nharaunda dzinoputika, uye nharaunda dzinoshanda pasi pekupisa kwakanyanya (2552 ° F). Izvi zvivakwa zvinoita kuti sintered alpha silicon carbide yakanakira maapplication akadai semakemikari uye slurry pombi zvisimbiso uye mabhengi, nozzles, pombi uye valve trim, bepa uye machira zvinhu, nezvimwe.
