Cast Tungsten Carbide budada ah

1. Waa maxay budada kabka ee Tungsten Carbide?

Budada carbide tungsten ee kabka ah waxay ka kooban tahay qaybo cawl madow ah, kuwaas oo ay sameeyeen heerkul sare oo spheroidization ama habka atomization gaaska.

Qaab dhismeedka crystal Dendritic oo ka kooban WC iyo W2C: dhibic dhalaalaysa sare (2525 ℃), engegnaanta sare (HV0.1≥2700), qaab dhismeedka baalasha sare (content≥90%), kiimikaad deggan, qulquli heer sare ah, microhardness sare, iyo caabbinta xidho sare .

Alaabtan waxa loo isticmaalaa alaabta matrix birta daloolista saliidda dheeman, balaasma (PTA) alaabta dusha sare, alxanka buufiyo, iyo kororbide adkaysiga u adkaysta electrodes (silig).

2. Sidee loo soo saaraa?

Budada carbide tungsten wareegsan guud ahaan waxaa laga sameeyaa tungsten carbide quwada caadiga ah ama isku dhafka tungsten (W), tungsten carbide (WC), iyo carbon (C). Ugu horrayn waxaa jira laba hab oo wax-soo-saar: (1) isku darka budada tungsten ee lagu daray tungsten carbide iyo budada kaarboon ayaa marka hore dhalaali doonta. Isku darka dhalaalka ah ayaa markaa atomized lagu beddelaa atomizing wareeg ama heerkul aad u sarreeya oo dhalaalid & habka atomizing. Waxay spheroids gelisaa qaybo WC wareegsan inta lagu guda jiro habka adkeynta degdega ah sababtoo ah kacsanaanta dusha sare. (2) Nidaam kale ayaa ku salaysan wax ka beddelka budada carbide tungsten ee caadiga ah. Buufinta balaasmaha, soo saarista korantada, ama dhalaalidda foornada iska caabbinta korantada ayaa lagu dabaqaa inta lagu guda jiro habka spheroidization si loo helo qaybo qurux badan oo WC ah.

3. Sidee ku saabsan waxqabadkeeda jireed?

Wadarta kaarboonka la xakameyn karo;

Labbiska W2C iyo WC qaab-dhismeedka laba-waji;

Microhardness sare (HV0.1≥2700);

Nadiifin sare (≥99.9%);

Ogsajiinta hoose (≤100ppm);

Xajmiga sare (≥98%);

Dusha siman;

Ma jiraan kubbadaha dayax-gacmeedka;

Qaybinta cabbirka walxaha lebbiska ah;

Guryaha qulqulka wanaagsan (≤6.0s/50g);

cufnaanta cufnaanta sare (≥9.5g/cm3);

Cufnaanta tuubada (≥10.5g/cm3).

Budada carbide tungsten ee kabka ah waxay leedahay qaab-dhismeed-yar oo ah dendrites siman oo siman, sida ka muuqata sawirka kore. Sawirka SEM ee hoose wuxuu si cad u muujinayaa qaab-dhismeedkiisa qaybaha WC-ga ee isku cufan. Waxay ilaalisaa sifooyinka kiimikaad ee deggan, dabacsanaan iyo qallafsanaan wanaagsan, iyo caabbinta daalid/xiro aad u wanaagsan. Cabbirrada walxaha kabka budada WC ee kabka ah waa 0.025 mm ilaa 0.25 mm, kaas oo muujinaya dhalaal madow oo madow. Cufnaanta gaarka ah waa 15.8 ~ 16.7 g / cm3 oo leh qallafsanaan yar oo u dhexeeya 2700 ~ 3300 kg / mm2.

4. Maxay yihiin codsiyadoodu?

Budada carbide ee tungsten ee kabka ah ayaa si weyn loogu codsadaa adkeynta qashinka qodista iyo aaladaha qodista PDC, buufinta kuleylka HVOF ama PTA ee dusha sare ee kuraasta waalka ama marinnada gudaha, iyo dahaadhka alxanka ee meelaha u jeedda flange, iwm.
