Ngenxa yozinzo lobushushu obuphezulu, ukuchasana nokufuduka kwe-electron ephezulu kunye ne-electron ephezulu yokukhutshwa komlinganiso we-refractory tungsten kunye ne-tungsten alloys, i-high-purity tungsten kunye ne-tungsten alloy targets zisetyenziselwa ubukhulu becala ukwenza ii-electrodes zamasango, i-wiring yokudibanisa, i-diffusion barrier layers, njl. iisekethe ezihlanganisiweyo, kwaye zineemfuno eziphezulu zococeko, umxholo wento engacocekanga, ingxinano, ubungakanani obuziinkozo kunye nokufana kwesakhiwo senkozo zemathiriyeli. Ngoku makhe sijonge izinto ezichaphazela ukulungiswa kwethagethi ye-tungsten ephezulu.
1、 Isiphumo sobushushu be-sintering
Inkqubo yokwenza i-embryo ekujoliswe kuyo ye-tungsten yenziwa ngokubanzi ngokucinezela kwe-isostatic ebandayo. Ingqolowa ye-tungsten iya kukhula ngexesha lenkqubo ye-sintering. Ukukhula kwengqolowa ye-tungsten kuya kugcwalisa i-gap phakathi kwemida yeenkozo, ngaloo ndlela kuphuculwe ubuninzi bethagethi ye-tungsten. Ngokunyuka kwamaxesha e-sintering, ukwanda kwe-tungsten ekujoliswe kuyo kuyehla kancinci. Esona sizathu siphambili kukuba emva kokucofa okuninzi, umgangatho wethagethi ye-tungsten awutshintshanga kakhulu. Ngenxa yokuba ininzi ye-voids kumda weenkozo zizaliswe ngeekristale ze-tungsten, emva kokuhlambalaza ngalunye, ubungakanani bezinga lokutshintsha ubungakanani bethagethi ye-tungsten iye yancinci kakhulu, ibangele indawo encinci yokwandisa ubuninzi bethagethi ye-tungsten. Ngenkqubo ye-sintering, iinkozo ze-tungsten ezikhulile zizaliswe kwi-voids, okubangelwa ukuxinana okuphezulu kokujoliswe kuyo kunye nobukhulu bamancinci amancinci.
2. Isiphumo sokubamba ixesha
Kwiqondo lokushisa elifanayo le-sintering, ukudibanisa kwethagethi ye-tungsten kuya kuphuculwa kunye nokwandiswa kwexesha lokubamba i-sintering. Ngokwandiswa kwexesha lokubamba, ubungakanani bengqolowa ye-tungsten buya kunyuka, kwaye kunye nokwandiswa kwexesha lokubamba, amaxesha okukhula kobungakanani beenkozo aya kuthi chu kancinci, oku kuthetha ukuba ukwandisa ixesha lokubamba kunokuphucula ukusebenza kwe Ithagethi ye-tungsten.
3. Isiphumo sokuqengqeleka kwiipropati ekujoliswe kuzo
Ukuze kuphuculwe ubuninzi bezinto ezijoliswe kuyo ze-tungsten kunye nokufumana isakhiwo sokulungiswa kwezinto ezijoliswe kuyo, ukufudumala okuphakathi kwezinto ezijoliswe kuyo kufuneka kuqhutywe ngaphantsi kweqondo lokushisa kwakhona. Ukuba iqondo lokushisa elijikelezayo le-billet ekujoliswe kuyo liphezulu, i-fiber structure ye-billet ekujoliswe kuyo iya kuba rhabaxa, kwaye ngokuchaseneyo. Xa izinga lokufudumala lifikelela ngaphezu kwe-95%. Nangona umahluko kulwakhiwo lwefayibha obangelwa ziinkozo ezahlukeneyo zantlandlolo okanye amaqondo obushushu ahlukeneyo aqengqelekayo aya kupheliswa, ubume bangaphakathi bokujoliswe kuko kuyakwenza ulwakhiwo lwefayibha elinganayo, ngoko okukhona uphezulu izinga lokwenziwa kokuqengqeleka okufudumeleyo, kokukhona ukusebenza koko kujoliswe kuko kubhetele.
