Tantalum carbide hardness, siab melting point, siab kub kev ua tau zoo, feem ntau yog siv raws li ib tug hard alloy additive. Lub thermal hardness, thermal shock kuj thiab thermal oxidation kuj ntawm cemented carbide tuaj yeem txhim kho tau zoo los ntawm kev ua kom cov nplej loj ntawm tantalum carbide. Rau lub sijhawm ntev, ib qho tantalum carbide ntxiv rau tungsten carbide (los yog tungsten carbide thiab titanium carbide), thiab tus neeg sawv cev sib txuas cobalt hlau yog tov, tsim, sintered los tsim cov hlau alloy. Txhawm rau txo tus nqi ntawm cov tawv tawv, tantalum niobium compound carbide feem ntau siv. Tam sim no tus thawj siv ntawm tantalum niobium compound yog: TaC: NbC yog 80:20 thiab 60:40, thiab lub zog ntawm niobium carbide nyob rau hauv lub complex nce mus txog 40% (feem ntau tsis ntau tshaj 20% yog zoo dua).
