Impembelelo yomxholo we-W kwisigaba se-tungsten carbide crystal bonding kumandla okuguquguquka kwe-alloy

Amandla okugoba yipropathi ebaluleke kakhulu yomzimba ye-carbide enesamente.Kwi-alloys ephezulu ye-cobalt, amandla ayo ayanda ngokunyuka komxholo we-W;ngelixa i-low-cobalt alloys, okuchaseneyo kuyinyaniso.

Oku kungenxa yokuba emva kwesigaba se-cobaltingxubevange ye-cobalt ephezulusisisombululo esiqinileyo esomelezwa yi-W, ukuxhathisa kweplastiki ye-deformation ye-alloy kuphuculwe, ngaloo ndlela kwandisa amandla;ngelixa iingxubevange ye-cobalt ephantsii-brittle ngokwendalo, kwaye emva kokuba isigaba se-cobalt siqinile-isisombululo esomelezwe ngu-W, amandla ayancipha.Amandla e-alloy.

Ubudlelwane phakathi kokuxhatshazwa kokugqoka kunye nomxholo we-W kufuneka kuchazwe ngokusebenza kwesigaba sokubambisana.Ukuphakama komxholo we-W, ngakumbi i-cobalt iqiniswa kwaye iphakamileyo ukuchasana nokugqoka;i-alloy inomlinganiselo omncinci wesigaba se-eta esingathinteli ukuxhatshazwa kokugqoka ngexesha lokusetyenziswa.Nangona kunjalo, xa ubungakanani besigaba se-eta sikhulu, i-alloy i-brittle kwaye ijwayele ukukrazula okanye ukuphuka, kubangela umonakalo kwizixhobo ze-alloy.
