I-tungsten yensimbi, igama layo lisuselwa ku-Swedish - tung (esindayo) kanye ne-sten (itshe) isetshenziswa kakhulu ngesimo sama-tungsten carbides ayi-cemented. Ama-carbide anosimende noma izinsimbi eziqinile njengoba evame ukubizwa kanjalo ayikilasi lezinto ezenziwe 'ngokusimende' izinhlamvu ze-tungsten carbide ku-binder matrix ye-cobalt yensimbi ngenqubo ebizwa ngokuthi i-liquid phase sintering.
Namuhla osayizi bezinhlamvu ze-tungsten carbide bayahluka kusuka kumamicron angu-0.5 kuya kwangaphezu kwama-micron angu-5 ngokuqukethwe kwe-cobalt okungafika cishe ku-30% ngesisindo. Ngaphezu kwalokho, ukwengeza amanye ama-carbide nakho kungashintsha izakhiwo zokugcina.

Ngokushintsha usayizi wokusanhlamvu we-tungsten carbide kanye nokuqukethwe kwe-cobalt ku-matrix, kanye nokwengeza ezinye izinto, onjiniyela banokufinyelela ekilasini lezinto izakhiwo zazo ezingavunyelaniswa nezinhlelo zokusebenza ezihlukahlukene zobunjiniyela. Lokhu kuhlanganisa amathuluzi obuchwepheshe obuphezulu, izingxenye ezigqokwayo namathuluzi omkhakha wezimayini zokwakha kanye nowoyela negesi.
Imikhiqizo ye-Tungsten Carbide ingumphumela wenqubo ye-powder metallurgy esebenzisa ngokuyinhloko i-tungsten carbide nama-cobalt metal powders. Ngokuvamile, ukwakheka kwezingxube kuzohluka kusuka ku-4% ye-cobalt kuya ku-30% ye-cobalt.
Isizathu esiyinhloko sokukhetha ukusebenzisa i-tungsten carbide ukusizakala ngobulukhuni obuphakeme obuvezwa yilezi zinto, ngaleyo ndlela kubambezeleke izinga lokuguga lezingxenye ngazinye. Ngeshwa, inhlawulo exhunywe ebukhuni obuphezulu ukuntuleka kokuqina noma amandla. Ngenhlanhla, ngokukhetha izingoma ezinokuqukethwe okuphezulu kwe-cobalt, amandla angatholwa kanye nobunzima.
Khetha okuqukethwe kwe-cobalt ephansi kwezinhlelo zokusebenza lapho ingxenye ingeke ilindeleke ukuthi ibe nomthelela, ifinyelele ubulukhuni obuphezulu, ukumelana nokugqoka okuphezulu.
Khetha okuqukethwe okuphezulu kwe-cobalt uma uhlelo lokusebenza lubandakanya ukushaqeka noma umthelela futhi uzuze ukumelana nokuguga okukhulu kunezinye izinto eziningi ezinganikezwa, kuhlanganiswe nekhono lokumelana nomonakalo.
