Tungsten kunagwa kasakaniza wazitsulo

Mkulu osalimba, formability kwambiri ndi machinability, chabwino dzimbiri kukana, mkulu modulus wa elasticity, chidwi matenthedwe madutsidwe ndi otsika kuwonjezeka matenthedwe. Ife azipereka: tungsten wathu heavy metal kasakaniza wazitsulo.

Athu "heavyweights" ntchito Mwachitsanzo, ndege ndi Azamlengalenga mafakitale, mankhwala luso, ndi magalimoto ndi foundry mafakitale kapena mafuta ndi gasi pobowola. Ife mwachidule pano atatu awa pansipa:

tungsten wathu heavy metal kasakaniza wazitsulo W-Ni-Fe ndi W-Ni-Cu ndi osalimba makamaka mkulu (17.0 kuti 18,8 g / cm3) ndi kupereka kutetezedwa odalirika ndi X-ray ndi cheza Popanga madzi a gamma. Onse W-Ni-Fe ndipo sanali maginito zinthu zathu W-Ni-Cu ntchito kutetezedwa Mwachitsanzo mu ntchito zachipatala komanso mafuta ndi mpweya makampani. Monga collimators zipangizo cheza mankhwala iwo kuonetsetsa ndi kukhudzana zolondola. Mu kugwirizanitsa zolemera timagwiritsa ntchito osalimba makamaka mkulu wa tungsten heavy metal aloyi wathu. W-Ni-Fe ndi W-Ni-Cu kukuza yekha pang'ono kwambiri pa kutentha ndi dissipate kutentha makamaka bwino. Monga nkhungu oyika ntchito zotayidwa foundry, iwo akhoza mobwerezabwereza usavutike ndi utakhazikika popanda kukhala Chimaona.

Mu Magetsi kumaliseche Machining (EDM) ndondomeko, zitsulo ndi machined ku msinkhu kwambiri yolinganizika mwa kukha magetsi pakati pa workpiece ndi elekitirodi. Pamene mkuwa ndi graphite maelekitirodi si kuti ntchitoyo, kuvala zosagwira tungsten-copper- maelekitirodi amatha makina ngakhale zitsulo zolimba mosavuta. Mu madzi kutsitsi nozzles kwa makampani ❖ kuyanika, katundu zinthu tungsten ndi mkuwa kachiwiri amathandiza mwangwiro.

Walowerera zachitsulo tungsten zitsulo zigwirizana mwa zigawo ziwiri zakuthupi. Pa awiri gawo kupanga ndondomeko, ndi porous sintered m'munsi koyamba amapangidwa kuchokera mbali ndi mfundo apamwamba kusungunuka, mwachitsanzo zitsulo refractory, pamaso pa pores lotseguka ndiye walowerera ndi liquified chigawo ndi mfundo m'munsi kusungunuka. The katundu wa zigawo munthu kukhala sichinasinthe. Pamene anayendera pansi maso, ndi katundu aliyense wa zigawo zikuluzikulu kupitiriza kuonekera. Pa mlingo macroscopic Komabe, katundu zigawo zikuluzikulu munthu amaphatikizidwa. Monga wosakanizidwa zinthu zachitsulo, ndi zinthu zatsopano mwina Mwachitsanzo, adzalandira latsopano matenthedwe madutsidwe ndi mfundo matenthedwe kukula.

Madzi gawo-sintered tungsten-lolemera zitsulo amapangidwa kuchokera chisakanizo cha ufa zitsulo mu ndondomeko kupanga umodzi gawo imene zigawo ndi mfundo m'munsi limatsogolera ali anasungunuka kumtunda anthu mfundo apamwamba kusungunuka. Pa gawo binder, zigawo zikuluzikulu zimenezi kupanga kasakaniza wazitsulo ndi okhawo amene ali limatsogolera mfundo apamwamba. Ngakhale wambirimbiri tungsten, amene ali limatsogolera mfundo mkulu, uli kusungunuka pa gawo binder. Plansee a madzi gawo sintered gulu zipangizo kupindula kachulukidwe tungsten chigawo cha, modulus wa elasticity ndi luso kuyamwa X-ray ndi cheza Popanga madzi a gamma popanda kuvutika ndi aliyense wa zovuta kugwirizana ndi processing wa tungsten koyera Koma koyefishienti cha kuwonjezedwa matenthedwe ndi matenthedwe ndi magetsi madutsidwe wa madzi zigawo gawo-sintered zimadalira pamlingo kwambiri pa zikuchokera zinakhalira mu gawo binder.

Back-kuponya zipangizo imodzi kuphatikiza pa katundu chuma cha zigawo ziwiri zosiyana zakuthupi. Pa ndondomekoyi, zipangizo okha asungidwa mu chikhalidwe chawo choyamba ndipo sikumangidwa kokha pa mphambano woonda. zitsulo ndi zinaphatikizidwa mu nkhungu kupanga ubale wa micrometers ndi ochepa kukula. Mosiyana ndi njira kuwotcherera ndi soldering, njira imeneyi makamaka khola ndipo amaonetsetsa akadakwanitsira matenthedwe conduction.
