Izinsimbi ze-tungsten eziphikisayo kanye nama-tungsten alloys anezinzuzo zokuzinza kwezinga lokushisa eliphezulu, ukumelana okuphezulu nokufuduka kwe-electron kanye ne-coefficient ephezulu yokukhishwa kwe-electron. Amathagethi we-high-purity tungsten kanye ne-tungsten alloy asetshenziswa ngokuyinhloko ukwenza ama-electrode esango, izintambo zokuxhuma, izendlalelo zesithiyo sokusabalalisa zamasekethe ahlanganisiwe we-semiconductor. Zinezidingo eziphakeme kakhulu zokuhlanzeka, okuqukethwe kwesici sokungcola, ukuminyana, usayizi wokusanhlamvu kanye nesakhiwo sokusanhlamvu esifanayo sezinto. Ake sibheke izici ezithonya ukulungiswa kwethagethi ye-tungsten ephezuluby Rich Special Material Co., Ltd.
I. Umphumela Wezinga Lokushisa Le-Sintering
Inqubo yokwenza i-tungsten target embryo ngokuvamile yenziwa ukucindezela okubandayo kwe-isostatic. Izinhlamvu ze-tungsten zizokhula ngesikhathi sokucwiliswa. Ukukhula kokusanhlamvu kwe-tungsten kuzovala igebe phakathi kwemingcele yekristalu, ngaleyo ndlela kwandise ukuminyana kwethagethi ye-tungsten. Ngokukhula kwezikhathi ze-sintering, ukwanda kokuminyana kwethagethi ye-tungsten kwehla kancane kancane. Isizathu esiyinhloko ukuthi ikhwalithi yezinto ezihlosiwe ze-tungsten ayikashintshi kakhulu ngemva kwezinqubo eziningana zokugcoba. Ngenxa yokuthi ama-void amaningi emngceleni wekristalu agcwaliswa amakristalu e-tungsten, izinga lokushintsha kosayizi lilonke lethagethi ye-tungsten lincane kakhulu ngemva kwenqubo ngayinye yokusinkilisa, okuholela esikhaleni esilinganiselwe sokwanda kwethagethi ye-tungsten. Njengoba i-sintering iqhubeka, izinhlamvu ezinkulu ze-tungsten zigcwaliswa ku-voids, okuholela ekuqondisweni okuminyene ngosayizi omncane.
2. Umphumela wehudle ukulondolozwa Isikhathi
Ngezinga lokushisa elifanayo le-sintering, ukubumbana kwethagethi ye-tungsten kuyathuthukiswa ngokunyuka kwesikhathi sokushisa. Ngokukhula kwesikhathi se-sintering, usayizi wokusanhlamvu we-tungsten uyakhula, futhi ngokwandiswa kwesikhathi sokucwilisa, usayizi wokusanhlamvu ukhula kancane kancane. Lokhu kubonisa ukuthi ukukhulisa isikhathi se-sintering nakho kungathuthukisa ukusebenza kwethagethi ye-tungsten.
3. Umthelela we-Rolling ku-Target Pukusebenza kahle
Ukuze kuthuthukiswe ukuminyana kwezinto ezihlosiwe ze-tungsten futhi uthole isakhiwo sokucubungula sezinto ezihlosiwe ze-tungsten, ukushisa okuphakathi kwezinto ezihlosiwe ze-tungsten kumele kwenziwe ngaphansi kwezinga lokushisa le-recrystallization. Uma izinga lokushisa eligoqayo lethagethi lingenalutho liphezulu, ukwakheka kwefayibha yethagethi engenalutho iba mkhulu, kuyilapho lokho okungenalutho kwethagethi kucolekile. Lapho isivuno se-hot rolling singaphezu kwama-95%. Nakuba umehluko wesakhiwo sefayibha obangelwa ukubola okusanhlamvu kwasekuqaleni okuhlukile noma izinga lokushisa eliginqikayo lizoqedwa, ukwakheka kwefayibha elinganayo kuzokwakhiwa ngaphakathi kokuhlosiwe, ngakho-ke uma liphezulu izinga lokucubungula lokuginqika okufudumele, kuba ngcono ukusebenza kwethagethi.
