keɓance igiyar tungsten mai ɗaure don shafe-shafe
Hanyar samar da waya ta tungsten don suturar ruwa yawanci ya haɗa da matakai masu zuwa:
Zaɓin ɗanyen abu: Zaɓi foda mai ingancin tungsten azaman albarkatun ƙasa don samar da wayar tungsten. Haɗin foda: Ana haɗa foda tungsten tare da masu ɗaure da sauran abubuwan ƙari don samar da cakuda mai kama da juna, wanda sai a danna shi cikin tsari mai ƙarfi ta amfani da fasahar latsawa. Sintering: A compacted tungsten cakuda yana ƙarƙashin yanayin zafi mai ƙarfi a cikin yanayi mai sarrafawa don karkatar da barbashi tare don samar da ingantacciyar waya ta tungsten. Zane: Ana zana waya ta tungsten da aka siya ta cikin jerin matattun don samun diamita da ake so da kuma ƙarewar ƙasa mai santsi. Annealing: Zane tungsten waya za a iya annealed (a zafi magani tsari) don ƙara ductility da kuma kawar da wani saura damuwa. Jiyya na Sama: Wayar Tungsten na iya samun ƙarin jiyya na saman ƙasa, kamar tsaftacewa, gogewa ko shafa, don haɓaka dacewa da aikace-aikacen rufewa.
Waɗannan matakan na iya bambanta dangane da takamaiman buƙatun tsarin rufewar injin da kuma abubuwan da ake so na filament tungsten.
Tungsten waya yawanci amfani da injin shafa matakai saboda da babban narkewar batu, da kyau thermal watsin, da kuma low tururi matsa lamba a high yanayin zafi. Lokacin amfani da matsayin dumama kashi ko filament a cikin injin shafi tsarin, tungsten filament iya yadda ya kamata samar zafi don ƙafe shafi kayan kamar karafa ko tukwane. Wannan tsari na evaporation yana sa kayan shafa su kasance a ko'ina a ajiye su a kan farfajiyar ƙasa, suna samar da suturar bakin ciki, iri ɗaya. Tungsten waya ta ikon kiyaye tsarin mutunci da kuma tsayayya nakasawa a high yanayin zafi sa shi manufa domin injin shafa aikace-aikace, inda zafin jiki kula da kwanciyar hankali ne da muhimmanci ga cimma daidaito shafi sakamakon. Bugu da ƙari, ƙarancin tururi na tungsten yana tabbatar da ƙarancin gurɓataccen yanayi yayin dumama da tururi.
Gabaɗaya, ƙaƙƙarfan lambobin waya mai ƙarfi da juriya da zazzabi suna sa shi zaɓi mai dogaro don tsarin ɗakunan ajiya, taimaka wajen samar da ingancin suttura, uniform a kan substrate iri.
