Ihe Ngwa Ngwá Ọrụ Carbide Simented Na-ahụkarị

Ịtinye TaC (NbC) na carbide cemented bụ ụzọ dị irè iji kwalite arụmọrụ ya. Na alloys TiC/Ni/Mo, iji carbide dị ka WC na TaC dochie akụkụ nke TiC, nke na-enye ike ka mma, na-eme ka arụmọrụ carbide simented dịkwuo mma ma gbasaa oke ngwa ya. Mgbakwunye WC na TaC na-akwalite:

● Isi ike
● Mgbanwe mgbanwe
● Iguzogide nrụrụ rọba
● Ike okpomọkụ dị elu

Ọ na-emeziwanye conductivity thermal na thermal shock resistance, na-eme ka ngwá ọrụ ahụ dịkwuo mma maka nkwụsị nkwụsị. Na WC-Co alloys, a pụrụ imeziwanye arụmọrụ site na ịgbakwunye 0.5% na 3% (oke akụkụ) nke carbide dị ka TaC, NbC, Cr3C2, VC, TiC, ma ọ bụ HfC. Ebumnuche ndị bụ isi gụnyere:

● Nnụcha ọka
● Ịkwado ihe owuwu kristal na-edoghị anya na-enweghị nnukwu recrystalization
● Ịbawanye isi ike na iyi ihe mgbochi n'emebighị isi ike

Ọzọkwa, ihe mgbakwunye ndị a na-abawanye:

● Isi ike nke okpomọkụ
● Ike okpomọkụ dị elu
● Nguzogide ikuku

N'oge ịkpụ, ihe nkiri oxide siri ike, nke na-akwụghachi onwe ya, nke na-eguzogide nrapado na nke na-agbasa mgbe ị na-eji ígwè ụfọdụ ma ọ bụ alloys. Nke a na-eme ka nguzogide ngwa ọrụ ahụ dịkwuo mma ma na-abawanye ikike ya iguzogide iyi akwa na iyi n'úkwù. Uru ndị a na-apụtawanye ìhè ka ọdịnaya cobalt dị na carbide cimented na-abawanye.

● Carbide cemented nwere 1% ruo 3% (oke irighiri ihe) TaC (NbC) nwere ike iji igwe nkedo dị iche iche, gụnyere ihe nkedo siri ike na ihe nkedo alloy.
● Alloys cobalt dị ala nke nwere 3% ruo 10% (irighiri oke) TaC (NbC), dị ka YG6A, YG8N, na YG813, na-agbanwe agbanwe. Ha nwere ike hazie:

Igwe nkedo oyi kpọnwụrụ
Ihe nkedo ductile
Ọla na-abụghị igwe
Ihe siri ike na igwe dị ka igwe anaghị agba nchara, nchara siri ike na alloys dị elu.

A na-akpọkarị ihe ndị a dị ka ihe ndị na-eme ihe n'ozuzu (YW) .Ịbawanye ọdịnaya nke cobalt n'ụzọ kwesịrị ekwesị na-eme ka ike na ịdị ike nke ụdị carbide cimented dị otú a, na-eme ka ọ dị mma maka ịrụ ọrụ siri ike na nkwụsịtụ nke ihe ndị na-esi ike na-arụ ọrụ. Ngwa gụnyere:

● Ịkpụ nnukwu ihe nkedo ígwè na akpụ akpụ
● Ntugharị, nhazi, na-egwe ọka nke ígwè austenitic na alloys na-eguzogide okpomọkụ
● Ịrụ ọrụ na nnukwu akụkụ rake, nnukwu akụkụ ịkpụ, na ọkara na obere ọsọ
● Mgbanwe siri ike na-agbanye akpaaka, ọkara akpaaka na lathes ọtụtụ ngwaọrụ
● Nrụpụta ihe nrụpụta, hobs gear, na ngwaọrụ ndị ọzọ nwere ike dị elu.

N'ime alloys WC-TiC-Co, ọdịnaya TiC karịrị akarị na-abawanye mmetụta na mgbawa ọkụ, na-eduga n'ịkụri akụ. Ịgbakwunye TaC na obere-TiC, nnukwu cobalt WC-Ti-Co alloys na-emeziwanye:

● Isi ike
● Nguzogide okpomọkụ
● Nguzogide ikuku

Ọ bụ ezie na TiC na-ebelata nkwụsị nke ọkụ ọkụ, TaC na-akwụ ụgwọ maka nke a, na-eme ka alloy dị mma maka ịrụ ọrụ igwe. Na alloys TiC-Ni-Mo, ịgbakwụnye TiN, WC na TaC n'otu oge na-abawanye nke ọma:

● Isi ike
● Ike mgbanwe
● Nguzogide ikuku
● Nrụpụta ọkụ
