Jiilka cusub ee SiC walxaha koritaanka crystal

Iyada oo si tartiib tartiib ah loo soo saaro tiro badan oo ah substrates SiC, shuruudo sare ayaa loo soo bandhigay xasiloonida iyo ku celcelinta habka. Gaar ahaan, xakamaynta cilladaha, hagaajinta yar ama qulqulka goobta kulaylka ee foornada, waxay keeni doontaa isbeddello crystal ama kororka cilladaha. Muddada dambe, waa in aan wajahnaa caqabada ah "si dhakhso ah u koraan, dheer iyo dhumuc weyn, iyo koraya", marka lagu daro hagaajinta aragtida iyo injineernimada, waxaan sidoo kale u baahanahay qalab heerkul sare oo heer sare ah oo taageero ah. Isticmaal walxo horumarsan, koraa crystals horumarsan.

Isticmaalka aan habboonayn ee walxaha la isku qurxiyo, sida graphite, graphite porous, tantalum carbide budada, iwm ee goobta kulul waxay u horseedi doontaa cillado sida kordhinta kaarboonka. Intaa waxaa dheer, codsiyada qaarkood, qulqulka graphite dalool kuma filna, godadka dheeraadka ah ayaa loo baahan yahay si loo kordhiyo qulqulka. Garaafiga daloolsan ee leh daloolin sare ayaa wajahaya caqabadaha habaynta, saarista budada, xoqidda iyo wixii la mid ah.

VET waxay soo bandhigaysaa jiil cusub oo ah SiC crystal walxaha koraya ee kulaylka, carbide tantalum dalool ah. Bilawga aduunka

Xoogga iyo adayga tantalum carbide aad bay u sarreeyaan, ka dhigista dalool waa caqabad. Samaynta tantalum carbide dalool leh oo leh porosity weyn iyo nadiif sare waa caqabad weyn. Tiknoolajiyada Hengpu waxay soo saartay tantalum carbide dalool leh oo leh porosity weyn, oo leh ugu badnaan 75%, oo hogaaminaya adduunka.

Sifeynta qaybta gaaska, hagaajinta heerkulka deegaanka, jihada socodka walxaha, xakamaynta daadinta, iwm, ayaa la isticmaali karaa. Waxaa loo isticmaali karaa mid kale oo adag tantalum carbide (compact) ama tantalum carbide daahan ka Hengpu Technology si ay u sameeyaan qaybaha maxaliga ah oo leh hab socodka kala duwan.

Qaybaha qaar ayaa dib loo isticmaali karaa.
