Common classifications of cemented carbide

Carbiid sibidhku waxa uu leeyahay taxanayaal sifooyin aad u wanaagsan sida qallafsanaanta sare, xidhashada caabbinta, xoogga wanaagsan iyo adkaanta, caabbinta kulaylka, iyo iska caabinta daxalka. Gaar ahaan, adkeysigeeda sare iyo caabbinta xirashada ayaa ah mid aan isbeddelin xitaa heerkulka 500 ° C. , weli waxa uu leeyahay engegnaan sare oo ah 1000 ° C. Waxaa jira saddex nooc oo waaweyn oo carbide ah oo loogu talagalay qalabka wax lagu gooyo, carbide oo loogu talagalay aaladaha macdanta juqraafiyeed iyo carbide ee qaybaha u adkaysta.

1. Carbide qalabka wax lagu gooyo: Carbide qalabka wax lagu gooyo waxa loo qaybiyaa lix qaybood: P, M, K, N, S, iyo H iyadoo loo eegayo qaybaha kala duwan ee isticmaalka;

Nooca P: Alloy/dahab ku salaysan TiC iyo WC, oo leh Co (Ni+Mo, Ni+Co) xidhe ahaan. Inta badan waxaa loo isticmaalaa in lagu farsameeyo alaabta jilibka dheer, sida birta, birta la shubay, iyo birta shubka ah ee la jarjaray oo dheer. Habaynta; qaadashada darajada P10 tusaale ahaan, shuruudaha habaynta lagu dabaqi karo waa rogid, koobi rogid, dunta, iyo wax shiididda hoos xawaaraha goynta sare, dhexda iyo jajab yar xaaladaha iskutallaab ah;

Fasalka M: Alloy/daaha dahaarka ku salaysan WC, oo leh Co sida xidhe, iyo qadar yar oo TiC ah oo lagu daray. Waxaa caadi ahaan loo isticmaalaa in ka baaraandegidda birta ahama, birta shubka, birta manganese, birta kabka malleable, birta daawaha, Alloy cast birta, iwm .; darajada M01 Tusaale ahaan, waxay ku habboon tahay hagaajinta iyo caajisnimada wanaagsan ee xawaaraha sare ee jarida, culeyska yar, iyo xaaladaha gariirka.

Fasalka K: Alloy/daaha dahaarka ku salaysan WC, oo Co uu yahay xidheha, oo lagu daro qadar yar oo TaC iyo NbC ah. Inta badan waxaa loo isticmaalaa farsamaynta alaabta gaab-gaaban, sida birta shubka, birta qaboojiyay, birta kabka gaagaaban ee malleable, birta cawlan, iwm.

N-nooca: daawaha/daaha dahaarka ku salaysan WC, oo leh Co sida xidhe, iyo qadar yar oo TaC, NbC, ama CrC ah oo lagu daray. Waxaa inta badan loo isticmaalaa in lagu farsameeyo biraha aan birta ahayn iyo walxaha aan birta ahayn, sida aluminium, magnesium, balaastikada, alwaax, iwm.

Fasalka S: Alloy/daaha dahaarka ku salaysan WC, oo leh Co sida xidhe, iyo qadar yar oo TaC, NbC, ama TiC lagu daray. Waxaa guud ahaan loo isticmaalaa habaynta qalabka u adkaysta kulaylka iyo kuwa tayada sare leh, sida birta kulaylka u adkaysata, nikkel-iyo birta ka kooban kobalt. , ka baaraandegidda agabka aluminium titanium kala duwan;

Qaybta H: Alloys/daaha dahaarka ku salaysan WC, oo leh Co sida xidhaha, iyo qadar yar oo TaC, NbC, ama TiC lagu daray. Inta badan waxaa loo isticmaalaa habaynta alaabta adag, sida birta adag, birta la qaboojiyey, iyo walxo kale;

2. Carbide for Geological and Mining tools: Carbide for Geological and Mining tools waxa loo qaybiyaa qaybaha soo socda iyadoo loo eegayo qaybaha kala duwan ee isticmaalka:

A: Carbiid sibidh ah oo loogu talagalay qashinka qodista dhagaxyada; xaaladaha hawlgalka sida darajada GA05, oo ku habboon dhagax jilicsan ama dhagax adag dhexdhexaad ah oo leh quwad cufan oo uniaxial ah oo ka yar 60MPa, fasalka GA50/GA60 oo ku habboon xoogga cadaadiska uniaxial ee ka weyn 200MPa dhagax adag ama dhagax adag; marka tirada darajadu korodho, iska caabbinta xidhashada ayaa hoos u dhacda, adkaantana way korodhaa.

B: Carbide ee sahaminta juqraafiga;

C: Carbiid sibidh ah oo loogu talagalay qodista dhuxusha;

D: Carbide loogu talagalay qodista macdanta iyo saliidda goobta saliidda;

E: Kaarbiid sibidh ah oo loogu talagalay matrix xaashida isku dhafan;

F: Carbide majarafad barafka;

W: Carbide loogu talagalay qodista ilkaha;

Z: qaybaha kale;

Adkeysiga Rockwell ee daawaynta noocan ah waxay gaari kartaa HRA85 iyo wixii ka sareeya, xoog dabacsanaantuna waxay guud ahaan ka sareysaa 1800MPa.

3. Carbide ee qaybaha xidhashada u adkaysta: Qaybaha xidhashada u adkaysta ayaa loo qaybiyaa

S: Carbide lagu sawiro fiilooyinka birta ah, ulaha, iyo tuubooyinka, sida sawirista dhinta, xidhitaanka faraantiga, iwm.

T: Kaarbide ku shaabadeynta wuu dhintaa, sida nasashada shaambaynta xajiyeyaasha, kubbadda birta, iwm.

S: Kaarbide loogu talagalay qaybaha heerkulka sare iyo cadaadiska sare, sida dubbaha sare iyo dhululubada sariiraha ee dheeman synthetic.
