I-refractory tungsten metals kunye nee-alloys ze-tungsten zineenzuzo zokuzinza kobushushu obuphezulu, ukuchasana nokuhamba kwe-electron kunye ne-coefficient ephezulu yokukhutshwa kwe-electron. Iithagethi ze-tungsten eziphakamileyo kunye ne-tungsten alloy zisetyenziselwa ikakhulu ukwenza i-electrode yesango, i-wiring yokudibanisa, i-diffusion barrier layers yeesekethe ezidibeneyo ze-semiconductor. Zineemfuno eziphezulu kakhulu malunga nococeko, umxholo wento engcolileyo, ubuninzi, ubungakanani beenkozo kunye nesakhiwo esifanayo sezinto eziziinkozo. Makhe sijonge izinto ezichaphazela ukulungiswa kwethagethi ye-tungsten ephezuluby Rich Special Material Co.,Ltd.
I. Impembelelo yeSintering Temperature
Inkqubo yokwenziwa kwe-embryo ekujoliswe kuyo ye-tungsten ngokuqhelekileyo yenziwa luxinzelelo olubandayo lwe-isostatic. Ingqolowa ye-tungsten iya kukhula ngexesha lokutshisa. Ukukhula kwengqolowa ye-tungsten kuya kugcwalisa isithuba phakathi kwemida ye-crystal, ngaloo ndlela kwandisa ubuninzi bethagethi ye-tungsten. Ngokunyuka kwamaxesha e-sintering, ukunyuka koxinzelelo lwethagethi ye-tungsten kuncipha kancinci kancinci. Isizathu esona sizathu kukuba umgangatho wezinto ezijoliswe kuyo ze-tungsten awuzange utshintshe kakhulu emva kweenkqubo ezininzi ze-sintering. Ngenxa yokuba ininzi ye-voids kumda we-crystal izaliswe ngamakristali e-tungsten, ubungakanani bezinga lokutshintsha ubungakanani bethagethi ye-tungsten incinci kakhulu emva kwenkqubo nganye ye-sintering, ebangela ukuba kubekho indawo encinci ye-tungsten ekujoliswe kuyo ukwandisa. Njengoko i-sintering iqhubela phambili, iinkozo ezinkulu ze-tungsten zizaliswe kwi-voids, okukhokelela ekujoliswe kuyo okuxineneyo kunye nobukhulu obuncinci.
2. Isiphumo sehidla ugcino Ixesha
Kwiqondo lokushisa elifanayo le-sintering, ukubumbana kwezinto ezijoliswe kuzo i-tungsten kuphuculwe ngokunyuka kwexesha lokutshisa. Ngokunyuka kwexesha le-sintering, ubungakanani bengqolowa ye-tungsten buyanda, kwaye kunye nokwandiswa kwexesha le-sintering, ubungakanani bokukhula okuziinkozo buyancipha kancinci kancinci. Oku kubonisa ukuba ukwandisa ixesha le-sintering kunokuphucula ukusebenza kwethagethi ye-tungsten.
3. Isiphumo sokuRolling kwiThagethi Pukusebenza
Ukuze kuphuculwe ubuninzi bezinto ezijoliswe kuyo ze-tungsten kunye nokufumana isakhiwo sokulungiswa kwezinto ezijoliswe kuzo, ukuhanjiswa kweqondo lokushisa eliphakathi kwezinto ezijoliswe kuyo kufuneka zenziwe ngaphantsi kweqondo lokushisa lokuhlaziya. Xa iqondo lobushushu eliqengqelekayo ekujoliswe kulo liphezulu, ulwakhiwo losinga lwethagethi engenanto lutyebe ngakumbi, kanti olo lwethagethi olungenanto lucolekile. Xa isivuno esishushu singaphezulu kwama-95%. Nangona umahluko wesakhiwo sefayibha obangelwa kukutya okuziinkozo okuziinkozo okwahlukeneyo okanye ubushushu obuqengqelekayo buya kupheliswa, ulwakhiwo lwefayibha engaphezulu kwe-homogeneous luya kwenziwa ngaphakathi koko kujoliswe kuko, ngoko okukhona uphezulu umlinganiselo wokusetyenzwa kokuqengqeleka okufudumeleyo, kokukhona ukusebenza ngcono koko kujoliswe kuko.
