Ngaba ngokwenene itungsten carbide ayinakonakala?

I-carbide enesamenteinobunzima obuphezulu kakhulu, ngokuqhelekileyo phakathi kwe-HRA80 kunye ne-HRA95 (ubunzima be-Rockwell A).Oku kungenxa yokuba inxalenye ethile ye-cobalt, i-nickel, i-tungsten kunye nezinye izinto zongezwa kwi-carbide ene-cemented, eyenza ibe nokumelana okuphezulu kakhulu kunye nobunzima.Izigaba eziphambili ezinzima kwi-cemented carbide yi-tungsten carbide (WC) kunye ne-tungsten carbide cobalt (WC-Co), phakathi kwayo ukuqina kwe-WC kuphezulu kakhulu, nokuba nzima kunedayimane.I-cobalt kwi-WC-Co imathiriyeli inokunyusa ukuqina kunye nokumelana nokubola kwezinto.Kufuneka kuqatshelwe ukuba ubunzima be-carbide ene-cemented buhambelana nokubunjwa kweekhemikhali, inkqubo yokulungiselela, ukuxinana kwebhloko kunye nezinye izinto, kunye nobunzima beentlobo ezahlukeneyo ze-carbide ene-cemented zingahluka.

I-carbide ene-cemented inobunzima obuphezulu kunye nokumelana nokugqoka, kwaye ihlala isetyenziselwa ukusika izinto kunye nokwenza izixhobo.Kodwa akuzona zonke izinto ezinokuthi zinqunywe ngokulula okanye zicutshungulwe nge-carbide, kwaye kukho imida.Umzekelo, ukusika ukusebenza kweizixhobo carbidezinokwahluka xa usikwa iintlobo ezahlukeneyo zentsimbi.

Xa usika iintsimbi ezinzima, izixhobo ze-carbide zihlala zifuna iingubo ezikhethekileyo okanye i-geometric designs ukugcina ukusebenza kwazo.Kwangaxeshanye, izixhobo ze-carbide zesamente azikwazi ukusika izinto ezinqabileyo kakhulu, njengeglasi kunye neekeramics.Ngoko ke, i-carbide ene-cemented ayikho ngokupheleleyo ngaphandle kwemida.Kufuneka isetyenziswe kwiimeko ezithile zesicelo kwaye kufuneka iphuculwe ngokudibanisa nezinye izinto okanye iindlela zokuyila.
