Kana zvasvika pazviumbwa zvesimbi zvesilicon carbide, kune mhando mbiri huru: reaction bonded ne sintered. Kunyange zvazvo mhando dzese dzeceramics dzichipa mwero wepamusoro wekugara kwenguva refu uye kuramba kupfeka, pane misiyano mikuru pakati pezviviri izvi.
Ngatitangei nesimbi dzesilicon carbide dzinobatanidzwa ne reaction bonded. Simba iri riri pakati pe85% ne90% silicon carbide uye rine silicon. Kudzivirira kwaro kupisa kwakanyanya i1380°C. Chimwe chezvakanakira zvikuru zvesimbi dzesilicon carbide dzinobatanidzwa ne reaction-bonded ndechekuti dzinogona kugadzirwa zvichienderana nehukuru hwakakura uye maumbirwo. Izvi zvinoita kuti zvive zvinhu zvakanaka zvekugadzira zvigadzirwa zvakasiyana uye zvehunyanzvi. Pamusoro pezvo, kuwedzera kwakaderera uye kuramba kupfeka kwakanaka kwesimbi idzi zvinoita kuti dzive sarudzo yakakurumbira muindasitiri yemigodhi.
Iyo silicon carbide isina kumanikidzwa ine huwandu hwakanyanya hwesilicon carbide, iyo inogona kusvika kupfuura 99%, uye kudzivirira kwakanyanya kupisa i1650°C. Imwe coefficient yekuwedzera inounzwa panguva yekupiswa, izvo zvinoita kuti SiC isina kumanikidzwa ive yakakodzera kugadzira zvikamu zveSiC zvakarurama. Nekuda kwekunyatsojeka kwayo, silicon carbide isina kumanikidzwa inowanzoshandiswa kugadzira maforoma uye zvikamu zvinodzivirira kupfeka.
Pamusoro pemaforoma akanyatsogadzirwa uye zvikamu zvekusakara, michina yemhando yepamusoro yeindasitiri yemakemikari inogona kushandisa mukana wekudzivirira kupisa kwakanyanya kwesilicon carbide isina kumanikidzwa. Kune avo vari kutsvaga machubhu ekupisa anoshanda zvakanaka emidziyo yavo yekugadzirisa makemikari, silicon carbide isina kumanikidzwa isarudzo yakanaka yezvinhu.
Kazhinji, reaction bonding uye SiC ceramics isingadzvinyiriri, kunyangwe imwe neimwe iine zvayakanakira nezvayakaipira, zvakakodzera kumaindasitiri akasiyana uye mashandisirwo ayo. Kana uchida chigadzirwa chakasiyana kana chikuru chinogona kutsungirira kusakara, reaction bonding silicon carbide ceramics inogona kunge iri sarudzo yakakunakira. Kune zvikamu zvakapfava zvinoda kutsungirira tembiricha yakakwira, silicon carbide isingadzvinyiriri inogona kunge iri sarudzo iri nani. Pasinei nerudzi rwesilicon carbide ceramic rwaunosarudza, unogona kuva nechokwadi chekuti ruchapa kugara kwenguva refu uye kuchengetedzeka kweprojekiti yako.
