Carbide ya tantalum

Tantalum karbide (TaC)ni ultra-high temperature ceramic material hamwe nubushyuhe bwo hejuru, ubukana bwinshi, ubwinshi; isuku ryinshi, ibirimo umwanda <5PPM; nubushakashatsi bwimiti kuri ammonia na hydrogen mubushyuhe bwinshi, hamwe nubushyuhe bwiza.

Ibyo bita ultra-high temperature ceramics (UHTCs) mubisanzwe bivuga icyiciro cyibikoresho bya ceramic bifite aho bishonga birenga 3000 ℃ kandi bigakoreshwa mubushyuhe bwinshi hamwe nibidukikije byangirika (nkibidukikije bya ogisijeni) hejuru ya 2000 ℃, nka ZrC, HfC, TaC, HfB2, ZrB2, HfN, nibindi

Tantalum karbideifite aho ishonga igera kuri 3880 ℃, ifite ubukana bwinshi (ubukana bwa Mohs 9-10), ubwinshi bwumuriro (22W · m-1 · K-1), imbaraga nini zunama (340-400MPa), hamwe na coefficient ntoya yo kwagura ubushyuhe . Ifite imiti ihuza imiti hamwe nubukanishi hamwe na grafite na C / C. Kubwibyo,Ibikoresho bya TaCzikoreshwa cyane mukurinda ubushyuhe bwikirere, gukura kristu imwe, ibikoresho bya elegitoroniki, nibikoresho byubuvuzi.

Tantalum karbide (TaC)ni umunyamuryango wa ultra-high temperature ceramic family!

Mugihe indege zigezweho nkibinyabiziga byo mu kirere, roketi, na misile bitera imbere bigana ku muvuduko mwinshi, umuvuduko mwinshi, hamwe n’ubutumburuke buri hejuru, ibisabwa kugira ngo birusheho guhangana n’ubushyuhe bwo hejuru no kurwanya okiside y’ibikoresho byo hejuru mu bihe bikabije bigenda byiyongera. Iyo indege yinjiye mu kirere, ihura n’ibidukikije bikabije nk’ubushyuhe bwinshi bw’umuvuduko mwinshi, umuvuduko ukabije w’umuvuduko mwinshi, hamwe n’umuvuduko ukabije w’umuyaga, ndetse no gukuraho imiti biterwa no kwitwara hamwe na ogisijeni, umwuka w’amazi, na dioxyde de carbone. Iyo indege igurutse hanze ikajya mu kirere, umwuka uzengurutse izuru ryayo n'amababa bizagabanuka cyane kandi bitere ubushyamirane bukabije hejuru y’indege, bigatuma ubuso bwayo bushyuha n’umwuka. Usibye gushyukwa mu kirere mu gihe cy'indege, ubuso bw'indege buzanagira ingaruka ku mirasire y'izuba, imirasire y'ibidukikije, n'ibindi mu gihe cyo guhaguruka, bigatuma ubushyuhe bwo hejuru bw'indege bukomeza kwiyongera. Ihinduka rizagira ingaruka zikomeye kumiterere yindege.

Ifu ya Tantalum karbide ni umwe mubagize umuryango wa ceramic ukabije cyane. Ikibanza cyayo cyo gushonga hamwe nubushyuhe buhebuje bwa termodinamike ituma TaC ikoreshwa cyane mumpera zishyushye zindege, kurugero, irashobora kurinda hejuru yubuso bwa moteri ya roketi nozzle.
