Ndeupi musiyano uripo pakati pekuita bonded uye sintered silicon carbide?

Kana zvasvika kune silicon carbide ceramics, kune maviri makuru marudzi:reaction yakasungirirwa silicon carbideuye sintered silicon carbide. Nepo ese ari maviri marudzi emakeramiki achipa yakakwira nhanho yekusimba uye kupfeka kuramba, pane mimwe misiyano yakakosha pakati pezviviri.

Ngatitangei nekuita bonded silicon carbide ceramics. Aya maceramics ari pakati pe85% ne90% silicon carbide uye ane mamwe silicon. Kunyanya kupisa kwavo kunopesana ne1380 ° C. Imwe yemabhenefiti makuru ekuita-yakasungirirwa silicon carbide ceramics ndeyekuti inogona kugadzirwa kune yakakura saizi uye maumbirwo. Izvi zvinovaita zvinhu zvakanaka zvekugadzira zvigadzirwa zvakasarudzika uye zvehunyanzvi. Pamusoro pezvo, iyo yakaderera coefficient yekuwedzera uye yakanakisa kupfeka kuramba kweaya ceramics inoita kuti ive sarudzo yakakurumbira muindasitiri yemugodhi.

Iyo isina pressure sintered sintered silicon carbide ine yakakwira yesilicon carbide, inogona kusvika kupfuura 99%, uye yakanyanya tembiricha kuramba i1650 ° C. Imwe coefficient yekuwedzera inounzwa panguva yekuita sintering, izvo zvinoita kuti isina kudzvanywa sintered SiC yakanakira kugadzira chaiyo SiC zvikamu. Nekuda kwekurongeka kwayo, isina kudzvanywa sintered silicon carbide inowanzo shandiswa kugadzira mold uye kusapfeka-inodzivirira chaiyo zvikamu.

Kuwedzera kune chaiyo mold uye zvipfeko zvekupfeka, yakakwirira-yekupedzisira migodhi yeindasitiri yemakemikari inogona kutora mukana wepamusoro tembiricha kuramba kwekusamanikidzwa sintered silicon carbide. Kune avo vari kutsvaga anoshanda anoshanda kupisa machubhu emidziyo yavo yekugadzira makemikari, isina kumanikidzwa sintered silicon carbide zvirokwazvo isarudzo inoshanda.

Kazhinji, reaction bonding uye kusamanikidzwa sintering yeSiC ceramics, kunyangwe imwe neimwe iine zvayakanakira nezvayakaipira, inokodzera maindasitiri akasiyana uye maapplication. Kana iwe uchida yakasarudzika kana yakakura saizi chigadzirwa chinogona kumira kupfeka, reaction bonded silicon carbide ceramics inogona kunge iri sarudzo yakakunakira iwe. Kune zvimwe zvakatetepa zvikamu zvinoda kumira tembiricha yakakwira, isina pressure sintered silicon carbide inogona kunge iri sarudzo iri nani. Hazvina mhosva kuti ndeupi rudzi rwesilicon carbide ceramic yaunosarudza, unogona kuva nechivimbo kuti ichapa kusimba uye kusimba kwepurojekiti yako inoda.
