Tantalum carbide hardness, high melting point, high temperature performance, feem ntau yog siv los ua cemented carbide additive. Qhov thermal hardness, thermal shock resistance thiab thermal oxidation resistance ntawm cemented carbide tuaj yeem txhim kho tau zoo los ntawm kev nce qhov loj ntawm cov noob ntawm tantalum carbide. Tau ntev, ib qho tantalum carbide ntxiv rau tungsten carbide (lossis tungsten carbide thiab titanium carbide), thiab cov hlau cobalt uas yog binder yog sib xyaw, tsim, thiab sintered los ua cemented carbide. Yuav kom txo tus nqi ntawm cemented carbide, feem ntau siv tantalum niobium complex carbide, tam sim no tantalum niobium complex siv tseem ceeb yog: TaC:NbC yog 80:20 thiab 60:40, niobium carbide hauv complex zog ncav cuag 40% (feem ntau xav tias tsis pub tshaj 20% yog qhov zoo).
