I-tungsten yensimbi, egama layo lisuselwa ku-Swedish - tung (esindayo) kanye ne-sten (itshe) isetshenziswa kakhulu ngendlela yama-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 ukusuka kuma-micron angu-0.5 ukuya 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.
