motsoako oa Kovar 4j29

4J29 alloy e boetse e tsejoa e le motsoako oa Kovar.Alloy e na le coefficient ea katoloso e tšoanang le ea khalase e thata ea borosilicate ho 20 ~ 450 ℃, sebaka se phahameng sa Curie le botsitso bo botle ba mocheso o tlase oa microstructure.Filimi ea oxide ea alloy e teteaneng 'me e ka kenngoa hantle ka khalase.Hape ha e sebelisane le mercury, e loketseng ho sebelisoa sesebelisoa se nang le mercury discharge.Ke thepa ea mantlha ea ho tiisa ea sesebelisoa sa vacuum ea motlakase.E sebelisetsoa ho etsa mochini oa Fe-Ni-Co alloy strip, bar, plate le pipe e nang le tiiso ea khalase e thata / ceramic, e sebelisoang haholo ho vacuum electronics, motlakase oa motlakase le liindasteri tse ling.
4J29 Kakaretso ea kopo le litlhoko tse khethehileng
Alloy ke motsoako o tloaelehileng oa ho tiisa khalase e thata ea Fe-Ni-Co e sebelisoang haholo lefatšeng.E 'nile ea sebelisoa ke fektheri ea lifofane ka nako e telele' me tshebetso ea eona e tsitsitse.E sebelisoa haholo bakeng sa ho tiisa khalase ea likarolo tsa vacuum ea motlakase tse kang emission tube, oscillation tube, ignition tube, magnetron, transistor, sealing plug, relay, lead lead lead line, chassis, shell, bracket, joalo-joalo. Coefficient ea ho atolosa ea khalase e khethiloeng le motsoako o lokela ho bapisoa.Ho tsitsisa ha lisele tsa mocheso tse tlase ho lekoa ka thata ho latela mocheso oa tšebeliso.Phekolo e nepahetseng ea mocheso e lokela ho etsoa ts'ebetsong ea ts'ebetso ho netefatsa hore thepa e na le ts'ebetso e ntle ea ho taka e tebileng.Ha u sebelisa thepa ea forging, ho tiea ha moea ho lokela ho hlahlojoa ka thata.
Covar alloy ka lebaka la dikahare tsa cobalt, sehlahisoa se batla se sa sebetse.
E ka tiisoa habonolo ka khalase ea sehlopha sa molybdenum, 'me bokaholimo bo akaretsang ba sesebediswa se hloka ho penta ka khauta.
4J29 Formability:
Alloy e na le thepa e ntle ea ho sebetsa e batang le e chesang, 'me e ka etsoa ka libopeho tse fapaneng tse rarahaneng tsa likarolo.Leha ho le joalo, ho futhumatsa sebakeng se nang le sebabole ho lokela ho qojoa.Ha mocheso o batang, ha sekhahla sa sekhahla se batang se feta 70%, anisotropy ea polasetiki e tla susumetsoa ka mor'a hore e koalehe.Ha sekhahla sa serame se batang se le ka har'a 10% ~ 15%, lijo-thollo li tla hōla ka potlako ka mor'a ho kenngoa, 'me anisotropy ea polasetiki ea alloy le eona e tla hlahisoa.Anisotropy ea polasetiki e tlase ha sekhahla sa khatello ea ho qetela e le 60% ~ 65% mme boholo ba lijo-thollo ke 7 ~ 8.5.
Thepa ea 4J29 Welding:
The alloy e ka tšeloa ka koporo, tšepe, nickel le lisebelisoa tse ling ka brazing, fusion welding, resistance welding, joalo-joalo. petso ea weld.Pele motsoako o koaletsoe ka khalase, o lokela ho hloekisoa, o lateloe ke phekolo e phahameng ea mocheso oa metsi a hydrogen le phekolo ea pele ho oxidation.
Ts'ebetso ea kalafo ea 4J29: Phekolo ea holim'a metsi e ka ba ho phatloha ha lehlabathe, ho bentša, ho kha.
Ka mor'a hore likarolo li koaloe ka khalase, filimi ea oxide e hlahisoang nakong ea ho tiisa e lokela ho tlosoa bakeng sa ho chesehela habonolo.Likarolo li ka futhumatsoa hoo e ka bang 70 ℃ ka tharollo e nang le metsi a 10% hydrochloric acid + 10% nitric acid, 'me e kenngoa ka 2 ~ 5min.
Alloy e na le ts'ebetso e ntle ea electroplating, 'me bokaholimo bo ka beoa ka khauta, silevera, nickel, chromium le lisebelisoa tse ling.E le ho nolofatsa ho tjheseletsa kapa ho tjheseletsa maqhama pakeng tsa dikarolo, hangata ho kenngwa ka koporo, nickel, khauta le thini.E le ho ntlafatsa conductivity ea maqhubu a phahameng a hona joale le ho fokotsa ho hanyetsa ho kopana ho etsa bonnete ba hore litšobotsi tse tloaelehileng tsa ho ntša cathode, hangata khauta le silevera li pentiloe.E le ho ntlafatsa ho hanyetsa ha kutu ea sesebelisoa, nickel kapa khauta e ka kenngoa.
4J29 Ts'ebetso ea ho seha le ho sila:
Litšobotsi tsa ho itšeha tsa alloy li tšoana le tsa tšepe e sa hloekang ea austenitic.Ho sebetsa ka tšepe e phahameng kapa sesebelisoa sa carbide, ts'ebetso ea ho itšeha ka lebelo le tlase.Coolant e ka sebelisoa ha ho khaola.Alloy e na le ts'ebetso e ntle ea ho sila.
