Sintering-free sintering ya silicon carbide: nyengo yatsopano yokonzekera kutentha kwambiri

Zinthu zakuthupi pansi pa kukangana, kuvala komanso kutentha kwambiri zikuchulukirachulukira, ndipo kutuluka kwa zida za silicon carbide zopanda atolankhani zimatipatsa yankho lanzeru. Pressureless sintered silicon carbide ndi chinthu cha ceramic chomwe chimapangidwa ndi sintering silicon carbide powder pansi pa kupanikizika kochepa kapena kusakhala ndi zovuta.

Njira zachikhalidwe za sintering nthawi zambiri zimafuna kupanikizika kwambiri, zomwe zimawonjezera zovuta komanso mtengo wakukonzekera. Kutuluka kwa njira yosakhala yokakamiza ya silicon carbide kwasintha izi. Popanda kukakamizidwa, ufa wa silicon carbide umaphatikizidwa pa kutentha kwakukulu kudzera mu kufalikira kwa matenthedwe ndikuchitapo kanthu kuti apange chinthu chowundana cha ceramic.

Sintered silicon carbide popanda kukakamiza ili ndi zabwino zambiri. Choyamba, zinthu zomwe zakonzedwa ndi njirayi zimakhala ndi kachulukidwe kakang'ono kwambiri komanso kachulukidwe kakang'ono, komwe kamapangitsa kuti makinawo aziwoneka bwino komanso kukana kwa zinthuzo. Kachiwiri, palibe zida zowonjezera zokakamiza zomwe zimafunikira pakanthawi kochepa, zomwe zimathandizira kukonzekera ndikuchepetsa mtengo. Kuphatikiza apo, njira yopangira sintering yosakakamiza imatha kuzindikiranso kukonzekera kwa kukula kwakukulu ndi mawonekedwe ovuta azinthu za silicon carbide, ndikukulitsa gawo logwiritsira ntchito.

Zida za Sintered silicon carbide popanda kukakamizidwa zimakhala ndi kuthekera kosiyanasiyana pakugwiritsa ntchito kutentha kwakukulu. Zitha kugwiritsidwa ntchito mu masitovu otentha kwambiri, masensa otentha kwambiri, zida zamagetsi ndi zakuthambo. Chifukwa cha kukhazikika kwake kwa kutentha kwambiri, kukana kuvala komanso kutenthetsa kwamafuta, zida za sintered silicon carbide zopanda zosindikizira zimatha kupirira kutentha kwambiri komanso zovuta zogwirira ntchito.

Komabe, pali mavuto ena pokonzekera ndondomeko sanali kukakamiza sintering pakachitsulo carbide, monga kulamulira sintering kutentha ndi nthawi, ufa kubalalitsidwa ndi zina zotero. Ndi kuwongolera kwina kwaukadaulo ndi kafukufuku wozama, titha kuyembekezera kugwiritsa ntchito kwakukulu ndikusintha kwina kwa magwiridwe antchito a silicon carbide osagwiritsa ntchito mphamvu pazida zotentha kwambiri.

Mwachidule, non-pressure sintered silicon carbide imatsegula nthawi yatsopano yokonzekera zipangizo zotentha kwambiri pochepetsa njira yokonzekera, kukonzanso katundu ndi kukulitsa ntchito. Ndi chitukuko chaukadaulo, zinthu zosagwiritsa ntchito sintered silicon carbide zidzawonetsa kuthekera kwakukulu pakutentha kwambiri ndikubweretsa ntchito zatsopano kumakampani osiyanasiyana.
