Boima bo phahameng, sebopeho se setle le machinability, khanyetso e ikhethang ea kutu, modulus e phahameng ea elasticity, conductivity e tsotehang ea mocheso le katoloso e tlase ea mocheso.Re hlahisa: li-alloys tsa rona tsa tungsten heavy metal.
"Li-heavyweights" tsa rona li sebelisoa, mohlala, indastering ea lifofane le lifofane, theknoloji ea bongaka, indasteri ea likoloi le tsa motheo kapa bakeng sa ho cheka oli le khase.Ka bokhutšoanyane re hlahisa tse tharo tsa tsena ka tlase:
Li-alloys tsa rona tsa tungsten heavy metal W-Ni-Fe le W-Ni-Cu li na le sekhahla se phahameng haholo (17.0 ho 18.8 g/cm3) 'me se fana ka tšireletso e tšepahalang khahlanong le mahlaseli a X-ray le gamma.Ka bobeli W-Ni-Fe le thepa ea rona eo e seng ea makenete ea W-Ni-Cu e sebelisetsoa ho sireletsa ka mohlala ts'ebelisong ea bongaka empa hape le indastering ea oli le khase.E le li-collimator lisebelisoa tsa kalafo ea radiation li netefatsa ho pepeseha ho nepahetseng.Ha re leka-lekanya litšepe re sebelisa matla a phahameng haholo a alloy ea rona ea tungsten ea tšepe e boima.W-Ni-Fe le W-Ni-Cu li atoloha hanyane haholo mochesong o phahameng 'me li senya mocheso hantle haholo.Ha hlobo e kenngoa bakeng sa mosebetsi oa motheo oa aluminium, li ka futhumatsoa khafetsa le ho pholile ntle le ho senyeha.
Ts'ebetsong ea Motlakase oa Ts'ebetso ea Motlakase (EDM), litšepe li etsoa ka mokhoa o feteletseng oa ho nepahala ka mokhoa oa ho tsoa ha motlakase pakeng tsa workpiece le electrode.Ha li-electrode tsa koporo le tsa graphite li sa fihle mosebetsing, li-electrode tsa tungsten-copper tse sa sebetseng li khona ho mochini esita le litšepe tse thata ntle le bothata.Ho li-nozzles tsa plasma bakeng sa indasteri ea ho roala, thepa ea tungsten le koporo e boetse e tlatsana hantle.
Metako e boima e kentsoeng ea tungsten e na le likarolo tse peli tsa thepa.Nakong ea ts'ebetso ea mekhahlelo e 'meli, setsi sa porous sintered se qala ho hlahisoa ho tloha karolong e nang le ntlha e phahameng ea ho qhibiliha, ka mohlala tšepe e hanyetsang, pele li-pores tse bulehileng li kenngoa ka karolo e nang le metsi le ntlha e tlaase ea ho qhibiliha.Thepa ea likarolo tsa motho ka mong e lula e sa fetohe.Ha e hlahlojoa ka tlas'a microscope, thepa ea karolo ka 'ngoe ea likarolo e tsoela pele ho bonahala.Leha ho le joalo, boemong ba macroscopic, thepa ea likarolo tsa motho ka mong e kopantsoe.Joaloka lisebelisoa tsa tšepe tse nyalisitsoeng, thepa e ncha, mohlala, e ka ba le conductivity e ncha ea mocheso le boleng ba ho atolosa mocheso.
Limetale tsa tungsten tse boima tsa mokelikeli li entsoe ho tsoa motsoakong oa phofo ea tšepe ka mokhoa o le mong oa tlhahiso nakong eo likarolo tse nang le lintlha tse tlase tse qhibilihang li qhibilihang ho tse nang le lintlha tse phahameng tsa ho qhibiliha.Nakong ea mohato oa ho kopanya, likarolo tsena li etsa li-alloys tse nang le sebaka se phahameng sa ho qhibiliha.Esita le palo e kholo ea tungsten, e nang le ntlha e phahameng ea ho qhibiliha, e qhibiliha nakong ea karolo ea binder.Lisebelisoa tse kopaneng tsa karolo ea mokelikeli ea Plansee's sintered composite li rua molemo ho bongata ba karolo ea tungsten, modulus ea elasticity le bokhoni ba ho monya mahlaseli a X-ray le gamma ntle le mathata a amanang le ts'ebetso ea tungsten e hloekileng Ka lehlakoreng le leng, coefficient ea keketseho ea mocheso le mogote le motlakase conductivity ea mokelikeli phase-sintered likarolo itšetlehile haholo haholo ka sebopeho se amehang mokhahlelong o kopanyang.
Lisebelisoa tsa morao-rao ka nako e le 'ngoe li kopanya thepa ea lintho tse peli tse fapaneng.Nakong ea ts'ebetso ena, lisebelisoa ka botsona li bolokiloe boemong ba tsona ba pele 'me li tlameletsoe feela sebakeng se tšesaane.Litšepe li kopanngoa ka foromo ho etsa tlamo ea li-micrometer tse seng kae feela ka boholo.Ho fapana le mekhoa ea ho tjheseletsa le ho solder, mokhoa ona o tsitsitse ka ho khetheha 'me o tiisa hore ho tsamaisoa hantle ha mocheso.
