Sharaxaada Alaabta

Tantalum carbide (TaC) waa walxo dhoobo ah oo aad u adag (Mohs hardess 9-10).Adayga waxa kaliya dhaafa dheeman.Waa budo bunni ah oo culus, sida caadiga ah waxaa lagu farsameeyaa sintering, iyo walxo cermet ah oo muhiim ah.Waxaa mararka qaarkood loo isticmaalaa sidii wax lagu daro ganaax-crystal ah oo loogu talagalay daawaha carbide tungsten.Tantalum carbide waxay leedahay farqiga u ahaanshaha iskudhafka binary stoichiometric ee leh barta dhalaalka ee ugu sareysa, at 4150 K (3880 ° C).Xarunta substoichiometric TaC0.89 waxay leedahay bar dhalaalaysa sare, oo u dhaw 4270 K (4000°C)

Codsiga

1) Tantalum carbide waxaa inta badan lagu daraa tungsten carbide / cobalt (WC / Co) budada attritions si kor loogu qaado sifooyinka jirka ee qaab-dhismeedka sintered.Waxa kale oo ay u shaqeysaa sidii horjoogayaasha korriinka hadhuudhka ee ka hortagaya samaynta miro waaweyn, sidaas darteed soo saarida alaabta adag ee ugu fiican.

2) Waxa kale oo loo isticmaalaa sida dahaarka loogu talagalay caaryada birta ee qaabaynta duritaanka ee aluminium aluminium.Iyadoo la siinayo dusha adag, xidho dusha iska caabbinta, waxay sidoo kale bixisaa dusha caaryada jilicsan oo hooseeya.

3) Tantalum carbide waxaa sidoo kale loo isticmaalaa soo saarista qalab fiiqan oo leh iska caabin farsamo oo aad u daran iyo qallafsanaan.

4) Waxa kale oo loo isticmaalaa qashin-qubka qalabka wax lagu gooyo.
