Izikhephe zeTungsten ezisetyenziselwa ukuphuphuma komphunga zihlala ziveliswa kusetyenziswa iinkqubo zesinyithi somgubo.La manyathelo alandelayo ngamanyathelo ngokubanzi okuvelisa isikhephe se-tungsten ukuze sibe ngumphunga:

Ukukhetha izinto ezikrwada: Khetha i-tungsten yensimbi ephezulu ecocekileyo, ngokuqhelekileyo ngococeko lwe-99.95%, njengeyona nto iphambili kwimveliso yeenqanawa ze-tungsten.Ukucoceka okuphezulu kuqinisekisa ukungcoliseka okuncinci ngexesha lokuphuma kwamanzi.Ukuxuba: Xuba ngononophelo i-tungsten powder usebenzisa izixhobo ezikhethekileyo ukuphumeza umxube we-homogeneous kunye neempawu zezinto eziphathekayo.I-Compaction: I-tungsten powder edibeneyo ifakwe kwi-mold kunye noxinzelelo oluphezulu lusetyenziswa, ngokuqhelekileyo ngokucinezela kwe-isostatic ebandayo (CIP) okanye i-uniaxial pressing.Inkqubo idibanisa umgubo kwimilo eshinyeneyo kwaye ehambelanayo efana nejometri yesikhephe esifunwayo.I-pre-sintering: Amacandelo e-tungsten adibeneyo afakwe ngaphambili kwiqondo lokushisa eliphezulu kwi-atmospheric elawulwayo, evumela ukuba iinqununu ze powder zidibanise kwaye zenze isakhiwo esiqinileyo sokwandisa amandla.I-Sintering: Iindawo ezisele zifakwe ngaphambili ziphantsi kobushushu obuphezulu be-sintering kwi-vacuum okanye umoya we-hydrogen.Le nkqubo igxininisa ngakumbi izinto, isusa ii-pores ezishiyekileyo, kwaye ikhuthaza ukukhula okuziinkozo, okukhokelela kwisikhephe esinamandla kunye esixineneyo se-tungsten.Ukucoca kunye nokugqiba: Emva kokucwina, isikhephe se-tungsten sinokungena kwimisebenzi ye-machining efana nokugaya, ukujika okanye ukugaya ukufezekisa imilinganiselo yokugqibela, i-grooves kunye nokugqiba umphezulu ofunekayo ukwenzela ukuba kubekho ukufudumala kwezinto eziphathekayo ngexesha lenkqubo yokuguquka.Ulawulo loMgangatho: Izikhephe ze-tungsten ezigqityiweyo zihlolwe ukuchaneka kobukhulu, imfezeko yomphezulu kunye nokucoceka kwempahla ukuqinisekisa ukuba ziyahlangabezana neemfuno ezichaziweyo zokusetyenziswa kwamanzi okuba ngumphunga.

Kuyo yonke inkqubo yokuvelisa, imilinganiselo engqongqo yolawulo lomgangatho kunye nokujongwa kwenkqubo kubalulekile ukuqinisekisa ukuba isikhephe se-tungsten sihlangabezana neemfuno ezingqongqo zenkqubo yokufunxa.Isikhephe esinesiphumo se-tungsten siyakwazi ukumelana namaqondo obushushu aphezulu kunye nemekobume eyonakalisayo, isenza ukuba silungele iinkqubo ezahlukeneyo zokufunxa umphunga kuwo wonke amashishini.
