Inkcazo
I-Niobium Carbide NbC,umgubo omdaka okhanyayo, kunye ne-sodium chloride uhlobo lwe-cubic crystal system, indawo yokunyibilika i-3490 ° C, indawo yokubilisa i-4300 ° C, ubuninzi be-7.56g / cm3, ayinyibiliki emanzini kunye ne-asidi ye-inorganic, kodwa i-soluble kwi-asidi edibeneyo ye-hydrofluoric acid kunye ne-nitric acid kwaye inokubola.I-Niobium Carbide ayinakusetyenziswa kuphela njengesongezo sokuthintela ukukhula kweenkozo ze-alloy ukucoca i-cemented carbide crystalline grain ekuveliseni i-carbide enesamente, kodwa kwakhona yenza isigaba sesithathu esisasazwayo kunye nezinye i-carbides ngaphandle kwe-WC kunye ne-Co, enokuphucula kakhulu. ukuqina kwe-thermal, ukuxhathisa ukothuka kwe-thermal, ukunyanzeliswa koxinzelelo olushushu kunye nokumelana ne-oxidation ye-carbide enesamente.Ngeenzuzo zokuphucula ukuqina kunye nokuqina kwe-fracture ye-alloy, ingasetyenziselwa ukulungiselela izixhobo ze-carbide ze-cemented isixhobo kunye nokusebenza okugqwesileyo kokusika.Ngaphandle koko, iyindawo ephezulu yokunyibilika, ubunzima obuphezulu kunye nokuzinza kweekhemikhali, i-NbC ikwasetyenziswa njengezinto zokumelana nobushushu obuphezulu kunye nezixhobo zokutshiza kwishishini le-aerospace.
Ukuhanjiswa
I-Niobium Carbide NbC kunye ne-Tantalum Carbide TaC e-Western Minmetals (SC) Corporation inokuhanjiswa ngokobungakanani bomgubo oyi-0.5-500 micron okanye i-5-400 mesh okanye njengoko kuchaziwe ngokwezifiso, ipakethe ye-25kg, 50kg kwingxowa yeplastiki enegubu lentsimbi ngaphandle.
