Igishushanyo hamwe na TaC

I. Gutunganya ibipimo byubushakashatsi

1. Sisitemu ya TaCl5-C3H6-H2-Ar

2. Ubushyuhe bwo kubitsa:

Ukurikije formula ya thermodynamic, ibarwa ko iyo ubushyuhe burenze 1273K, Gibbs imbaraga zubusa za reaction iba nkeya cyane kandi reaction iba yuzuye. Imyitwarire ihoraho KP nini cyane kuri 1273K kandi yiyongera vuba hamwe nubushyuhe, kandi umuvuduko wo gukura ugenda gahoro gahoro kuri 1773K.

Ingaruka ku buso bwa morphologie yubuso: Iyo ubushyuhe budakwiriye (hejuru cyane cyangwa hasi cyane), hejuru yerekana imyuka ya karubone yubusa cyangwa imyenge irekuye.

.

(2) Hariho itandukaniro riri hagati yikigereranyo cya pyrolysis ya alkane nigipimo cyo kugabanuka kwa tantalum pentachloride. Karubone ya pyrolysis irakabije kandi ntishobora guhuzwa na tantalum mugihe, bigatuma ubuso buzengurutswe na karubone.

Iyo ubushyuhe bukwiye, ubuso bwaIgikoresho cya TaCni Ubucucike.

TaCibice bishonga kandi byegeranya hamwe, uburyo bwa kristu bwuzuye, kandi imbibi zimbibi zigenda neza.

3. Ikigereranyo cya hydrogen:

Mubyongeyeho, hari ibintu byinshi bigira ingaruka kumiterere yo gutwikira:

-Garagaza ubuziranenge bwubuso

-Umurima wa gaze

-Urwego rwuburinganire bwo kuvanga gaze reaction

II. Inenge zisanzwe zatantalum karbide

1. Gupfundikanya ibice no gukuramo

Umurongo wo kwagura ubushyuhe bwa coefficient umurongo CTE:

2. Isesengura ryuzuye:

(1) Impamvu:

(2) Uburyo bwo kuranga

① Koresha X-ray itandukanya tekinoroji kugirango upime ibisigisigi.

② Koresha amategeko ya Hu Ke kugirango ugereranye imihangayiko isigaye.

(3) Inzira zifitanye isano

3.Gutezimbere guhuza imashini ya coating na substrate

(1) Ubuso muburyo bwo gukura

Ubushyuhe bwo kubitsa no gukwirakwiza ikoranabuhanga TRD

Uburyo bwo gushonga umunyu

Koroshya inzira yo gukora

Gabanya ubushyuhe bwa reaction

Ugereranije igiciro gito

Ibidukikije byangiza ibidukikije

Birakwiye kubyara umusaruro munini winganda

(2) Guteranya inzibacyuho

Igikorwa cyo gufatanya

CVDinzira

Ibice byinshi

Gukomatanya ibyiza bya buri kintu

Hindura byoroshye guhinduranya ibice hamwe nuburinganire

4. Gutanga ubushyuhe bwumuriro no gukwirakwiza ikoranabuhanga TRD

(1) Uburyo bwo Kwitwara

Ubuhanga bwa TRD nabwo bwitwa uburyo bwo gushira, bukoresha aside ya boric-tantalum pentoxide-sodium fluoride-boron oxyde-boron sisitemu yo guteguratantalum karbide.

Acide Amashanyarazi ya boric ashonga tantalum pentoxide;

Ent Tantalum pentoxide yagabanutse kuri atome ya tantalum ikora kandi ikwirakwira hejuru ya grafite;

At Atome ikora ya tantalum yamamajwe hejuru ya grafite kandi igakora na atome ya karubone kugirango ikoretantalum karbide.

(2) Urufunguzo rwo Kwitabira

Ubwoko bwa karbide bugomba kuba bujuje ibyangombwa bisabwa kugirango okiside itangwe imbaraga zubusa bwibintu bigize karbide iruta iya oxyde ya boron.

Gibbs imbaraga zubusa za karbide ni nkeya bihagije (bitabaye ibyo, boron cyangwa boride irashobora gushingwa).

Tantalum pentoxide ni oxyde idafite aho ibogamiye. Muri borax yubushyuhe bwo hejuru cyane, irashobora kwitwara hamwe na oxyde ya alkaline oxyde ya sodium oxyde kugirango ikore sodium tantalate, bityo igabanye ubushyuhe bwambere.
