Reaction-sintered silicon carbide ceramic, inozivikanwawo seRS-SiC, ndeyemhando yepamusoro ceramic zvinhu zvakakwezva kutarisisa kwakapararira nekuda kwekuita kwayo kwakanaka uye kuwanda kwekushandisa. Aya maceramics anogadzirwa kuburikidza nemaitiro anonzi reactive sintering, ayo anosanganisira kabhoni uye silicon ichiita pakudziya kwakanyanya kuumba silicon carbide. Iyo inokonzeresa zvinhu ine yakanakisa mechaniki, inopisa uye makemikari zvimiro, zvichiita kuti ive yakakodzera kune akasiyana siyana maindasitiri ekushandisa.
Imwe yemabhenefiti makuru ekuita-sintered silicon carbide ceramics ndiko kuomarara kwayo kwakasiyana uye kupfeka kuramba. Zvivakwa izvi zvinoita kuti zvive zvakanaka kuti zvishandiswe munzvimbo dzinonetsa dzakaita semigodhi, uko michina inosakara uye nekukukurwa. RS-SiC zvikamu zvakadai semapfekero-anodzivirira liner, nozzles uye impellers anoshandiswa zvakanyanya mukuita migodhi kuvandudza kusimba uye kushanda kwemidziyo yakafumurwa kune yakaoma zvinhu uye mamiriro. Kunyanya kupfeka kuramba kweRS-SiC ceramics kunobatsira kuderedza nguva yekudzikira uye mari yekugadzirisa, zvichiita kuti ive sarudzo yekutanga yekushandiswa kwemigodhi.
Pamusoro pemigodhi, reaction-sintered silicon carbide ceramics inoshandiswa zvakanyanya muindasitiri yemagetsi. RS-SiC's yakanakisa yekupisa conductivity uye yakanyanya kugadzikana tembiricha inoita kuti ive yakanakira zvinhu zvezvikamu mukugadzira magetsi uye kugovera masisitimu. Aya maceramics anoshandiswa mumashandisirwo akadai seyepamusoro-tembiricha yekudziya zvinhu, thermocouple ekudzivirira machubhu, uye insulating zvikamu zvemagetsi ekudzivirira. RS-SiC inokwanisa kumirisana nekupisa kwakanyanya uye kuvhunduka kwemafuta, zvichiita kuti ive sarudzo yakavimbika yezvikamu zvakakosha mumagetsi emagetsi uye masisitimu emagetsi.
Uyezve, iyo kemikari inertness ye reaction-sintered silicon carbide ceramics inoita kuti ive yakakodzera kushandiswa munzvimbo dzinoparadza. Iwo anopokana nekurwiswa kwemakemikari uye oxidation uye anoshandiswa mukugadzirwa kwemakemikari, metallurgical uye semiconductor kugadzira maindasitiri. Zvikamu zveRS-SiC zvinoshandiswa mumaitiro anosanganisira makemikari anoparadza, simbi dzakanyungudutswa uye magasi ekupisa kwepamusoro apo zvinhu zvakajairwa zvinogona kukanganisa kana kutadza. Iyo corrosion kuramba uye kugadzikana kweRS-SiC ceramics inobatsira kuwedzera michina hupenyu uye kuvimbika munzvimbo idzi dzakaoma.
Semugadziri mukuru weakagadziridzwa silicon carbide ceramic akakosha-akaumbwa zvikamu muChina, kambani yedu yakazvipira kupa-yakagadzirwa emhando yepamusoro RS-SiC zvikamu kuti isangane nezvinodiwa chaizvo zvemaindasitiri akasiyana. Isu tinopa akasiyana-akanyatso-engineered ceramic zvikamu, zvinosanganisira yakaoma geometries uye akaomarara madhizaini, kusangana nevatengi vedu zvakasiyana zvinodiwa. Unyanzvi hwedu mune reactive sintering tekinoroji inotibvumira kuburitsa maumbirwo akaomarara ane kushivirira kwakasimba, kuve nechokwadi chekuita kwakaringana uye hupenyu hwesevhisi yezvikamu zveceramic mumhando dzakasiyana dzekushandisa.
Iko kuita kwakasiyana-siyana kwekuita-sintered silicon carbide ceramics inopfuurira kupfuura iyo mechanic uye makemikari zvimiro. Aya maceramics anoratidzawo yakanakisa kuvharwa kwemagetsi, kuderera kwekuwedzera kwemafuta uye kuomarara kwepamusoro, zvichiita kuti ive yakakodzera kushandiswa mumainjiniya epamberi. Kugona kwavo kuchengetedza kudzikama pakupisa kwakanyanya uye nharaunda dzine hutsinye kunowedzera kukwirisa kwavo muaerospace, maindasitiri ezvemotokari nekudzivirira. RS-SiC zvikamu zvinoshandiswa mune aerospace propulsion system, mota mabhureki masisitimu uye zvombo zvekushandisa, uko hukuru hwavo hunobatsira hunobatsira kuvandudza mashandiro uye kuvimbika.
Muchidimbu, reaction-sintered silicon carbide ceramics inopa musanganiswa unomanikidza wezvivakwa izvo zvinoita kuti zvive zvakakosha mumhando dzakasiyana dzemaindasitiri ekushandisa. Kuomarara kwayo kwakasarudzika, kusamira kwekupfeka, kupisa kwemafuta uye kusagadzikana kwemakemikari kunoita kuti ive sarudzo yekutanga kune inodiwa nharaunda mumigodhi, kugadzirwa kwemagetsi, kugadzira makemikari uye mamwe maindasitiri. Semugadziri anotungamira weakagadziridzwa silicon carbide ceramic akasarudzika-akaumbwa zvikamu, kambani yedu yakazvipira kupa zvigadziriso zvinosimudzira zvakasarudzika mabhenefiti eRS-SiC kuzadzisa zvinogara zvichichinja zvinodiwa nevatengi vedu. Isu tinotarisa pamhando, kurongeka uye kugadzirisa, uye takazvipira kusimudzira mashandisirwo-sintered silicon carbide ceramics munzvimbo dzakasiyana siyana, zvichibatsira mukuvandudza mashandiro, kugona uye kuvimbika kweakakosha maindasitiri maitiro.
