Kugereranya inzira yo gushushanya karubide ya silikoni: inzira yo gusya n'ibyiza n'ibibi byayo

Ceramic ya silicon carbideKugereranya inzira yo gushushanya: inzira yo gusya n'ibyiza n'ibibi byayo

Mu gukora ibumba rya silicon carbide, gukora ni ikintu kimwe gusa mu gikorwa cyose. Gutunganya ni cyo gikorwa cy'ingenzi bigira ingaruka ku mikorere n'imikorere ya nyuma ya ceramic. Hari uburyo bwinshi butandukanye bwo gutunganya silicon carbide, buri bumwe bufite ibyiza n'ibibi byabwo. Muri iyi nyandiko ya blog, tuzasuzuma uburyo bwo gutunganya silicon carbide ceramics no kugereranya uburyo butandukanye.

1. Gutera ubwivumbure:
Uburyo bwo gusinya ibyuma bya silicon carbide buzwi cyane. Ubu buryo bworoshye kandi buhendutse cyane. Gusinya ibyuma bigerwaho hakoreshejwe uburyo bwo gusinya ibyuma ku bushyuhe buri hasi bwa 1450 ~ 1600 ° C n'igihe gito. Ubu buryo bushobora gukora ibice binini kandi bifite imiterere igoye. Ariko, bufite n'ibibi byabwo. Uburyo bwo gusinya ibyuma bya silicon butuma silicon idafite 8% ~ 12% muri silicon carbide, ibi bigabanya imiterere yayo mu bushyuhe bwinshi, kurwanya ingese, no kurwanya oxidation. Kandi ubushyuhe bwo gukoreshwa buri munsi ya 1350 ° C.

2. Gushyushya cyane:
Gushyushya no gushyushya ni ubundi buryo busanzwe bwo gushyushya ibintu bya silikoni. Muri ubu buryo, ifu ya silikoni yumye yuzura mu ibumba hanyuma igashyuha mu gihe ikoresha igitutu giturutse mu cyerekezo kimwe. Ubu buryo bwo gushyushya no gushyushya butuma ibice bikwirakwira, binyura, kandi bikwirakwira mu bwinshi, bigatuma silikoni ya silikoni ifite ibinyampeke bito, ubucucike bwinshi, n'imiterere myiza ya mekanike. Ariko, gushyushya no gushyushya bifite n'ibibi byabyo. Uburyo buragoye kandi busaba ibikoresho n'ibikoresho by'ibumba byiza. Umusaruro ni muto kandi igiciro ni kinini. Byongeye kandi, ubu buryo bukwiriye gusa ibicuruzwa bifite imiterere yoroshye.

3. Gushyushya gukanda isostatic:
Gushyushya imashini ikoresha HIP (Hot isostatic pressing - HIP) sintering ni uburyo bukoresha imbaraga zivanze z’umwuka ushyushye kandi ukoresha umuvuduko mwinshi. Ikoreshwa mu gushyushya no gukurura ifu ya silicon carbide ceramic, green body cyangwa body yashyizwemo sintering. Nubwo gushyushya imashini ikoresha HIP bishobora kunoza imikorere ya silicon carbide ceramics, ntabwo ikoreshwa cyane mu gukora ibintu byinshi bitewe n’uburyo ikorwamo bugoye kandi buhenze.

4. Gutera umwuka udashyushye:
Gutunganya ibintu bidakoresha umuvuduko ni uburyo bufite imikorere myiza cyane mu bushyuhe buri hejuru, uburyo bworoshye bwo gutunganya ibintu kandi buhendutse bwa silicon carbide ceramics. Bunatuma habaho uburyo bwinshi bwo kubikora, bigatuma biba byiza ku miterere igoye n'ibice binini. Ubu buryo burakwiriye cyane mu nganda nini zikora ibintu bya silicon ceramics.

Muri make, inzira yo gusya ni intambwe ikomeye mu gukora ibumba rya SiC. Guhitamo uburyo bwo gusya biterwa n'ibintu nk'imiterere yifuzwa ya ibumba, imiterere y'imiterere, ikiguzi cyo kuyikora n'ubushobozi bwayo. Buri buryo bufite ibyiza n'ibibi byabwo, kandi ni ngombwa gusuzuma neza ibi bintu kugira ngo hamenyekane inzira ikwiye yo gusya ikoreshwa mu buryo runaka.
