Nickel Titanium Alloy e Pulverized

Motsoako oa nickel-titanium

Binary alloy ea nickel le titan, kapa nitinol (kapa nitinol), e tsejoa e le "shape memory alloy". Li-alloys tsa memori ea sebopeho ke li-alloys tse khethehileng tse khutlisetsang deformation ea tsona ea polasetiki ka bo eona sebopeho sa mantlha ha li futhumatsoa. E na le sekhahla se phahameng sa katoloso ho feta 20%. Bophelo ba eona ba mokhathala ke hoo e ka bang 1 * 107. E na le thepa e phophomang ka makhetlo a 10 ho feta selemo se tloaelehileng. Ha e khone ho bola ho feta tšepe ea bongaka. Sena se etsa hore e be lisebelisoa tse fapaneng tse ka sebeletsang likopo tse ngata tsa boenjiniere le tsa bongaka.

Mosebetsi o ikhethang oa memori ea alloy ha se eona feela ntho e etsang hore e khethehe. Ntle le ho hanyetsa ha eona ho apara, ho hanyetsa kutu, superelasticity, le damping e phahameng le tsona li ntle haholo.

Phetoho e itšetlehileng ka mocheso le liphetoho tsa khatello ea mochine li ka baka mekhahlelo e 'meli ea kristale ho Nitinol alloy, the austenite le martensite. Tatelano ea phetoho ea karolo ea Nitinol alloy ke: karolo ea austenite joalo ka motsoali, ebe R mme qetellong martensite. Haeba karolo ea R e le rhomboid joale austenite ka mocheso o phahameng (o moholo ho feta o lekanang: mocheso oa austenite o qalile ho), kapa ka mor'a hore mojaro o tlosoe ke cube. Sebopeho sena se tsitsitse haholo. Mehato ea Martensite e batla e le tlaase mocheso, ka tlase ho Mf, kapa ha ho roala ho etsoa ka ntle. Li ka ba hexagonal le ductile.

Thepa ea 'Mele ea Nickel Titanium Alloy Powder

1) memori ea sebopeho. 1. Mohopolo oa sebopeho. Ha karolo ea motsoali e futhumatsoa ka tlase ho Mf ho theha martensite ho tsoa sebopehong se itseng, e hatsetsoa ka tlase ho Af ho theha martensite. Phetoho ea mekhahlelo e khutlisetsang morao e lumella thepa hore e tsosolose sebopeho sa eona sa pele. Haele hantle, mohopolo oa sebopeho ke phetoho ea mohato oa inductive ho Nitinol.

2) Superelasticity. 2) Superelasticity. Mohlala o ka ba le khatello e kholo ho feta moeli oa eona oa elastic ha o tlas'a matla a kantle. Mathata a ka khutlisoa habonolo ka ho laolla. Phetoho ea martensitic e bakoang ke khatello ea kelello e etsahala linthong tsa motsoali 'me e baka phetoho boitšoarong ba mechine. Molao oa Hooke ha o sebetse ho motsoako ona, kaha moeli oa eona oa elastic o phahame haholo ho feta oa thepa e tloaelehileng. Superelasticity ha e amehe ke matla a mocheso, ho fapana le thepa ea mohopolo oa sebopeho. Hyperelasticity, ka mantsoe a mang, e bolela hore khatello ea kelello ha e eketsehe ka ho eketseha ha khatello ho feta mefuta e mengata ea ho senyeha. O ka arola hyperelasticity ho hyperelasticity e sa tsitsang le ea linear. Ho na le kamano e batlang e lekana lipakeng tsa khatello ea maikutlo le khatello ea maikutlo ho graph ea khale ea khatello ea maikutlo. Nonlinear Hyperelasticity e bua feela ka martensitic e bakoang ke khatello ea kelello le liphetoho tsa eona tse fapaneng tse etsahalang nakong ea ho kenya / ho laolla. E boetse e tsejoa e le pseudo-elasticity phase transformation. Nitinol alloy e na le pseudo-elasticity ho pota 8%. O ka fetola maemo a kalafo ea mocheso ho fetola boleng ba Nitinol. Haeba maemo a phekolo ea mocheso a fetoloa ho 400C, joale superelasticity e tla fokotseha.

(3) Bohloko ba mocheso oa molomo. Mocheso oa mocheso oa molomo ha o na phello ho terata ea tšepe e sa hloekang kapa CoCr alloy tooth orthotic wire force. Ho fapana ha mocheso ho ama matla a orthodontic a superelastic Nitinol orthodonticwire. Haeba sekhahla sa deformation se lula se le teng, se tla fokotseha. Ha mocheso o ntse o phahama, matla a orthodontic aa hōla. Sesebelisoa sena se ka etsa hore mali a phalle libakeng tseo mali a tsielehileng. E tla potlakisa motsamao oa meno. Leha ho le joalo, Orthodontist ha e khone ho lekanya ka nepo le ho laola matla a ho lokisa tikolohong ea molomo.

4) Corrosion resistance. Lipatlisiso li bontšitse hore terata ea nickel-titanium corrosion resistance e ka bapisoa le ea terata e sa hloekang.

5) Ho hanyetsa chefo: Nickel titanium sebopeho sa memori alloy e ka bang 50% nickel. Nickel e tsebahala ka ho baka litlamorao tsa carcinogenic le ho khothaletsa mofets'e. Hobane motsoako oa Ni-Ti o na le biocompatibility e ntle, e sebetsa e le tšitiso ka ho kopanya lera la titanium. E kanna ea thibeloa ke TiXOy/TixNiOy sebakeng se kaholimo.

6) Matla a bonolo a orthodontic. Cobalt chrome-nickel wire, cobalt chrome-nickel wire, nickel-chromium alloywire, Australian alloywire, gold wire, soft orthodontic force ke mehlala ea mehala ea meno e rekisoang. Li-curve tsa phalliso ea lithapo tsena li ile tsa lekoa tlas'a maemo a thata le a mararo a kobehileng. Sethala sa ho laolla curve sa Nitinol se tlase haholo ebile se bataletse ka ho fetesisa. E bontša hore Nitinol e fana ka matla a molemo ka ho fetisisa le a bonolo ka ho fetisisa a khalemelo.

7) Ho monya hantle ho ts'oenyeha Ho bohlokoa ho monya ho ts'oenyeha hantle. Liphetho tsa boithuto li bonts'itse hore ho thothomela ha terata ea archwire ho kholo ho feta ha hyperelastic ni-titanium silk le super-elastic ni-titanium arwire. Bophahamo ba pele ba ho sisinyeha bakeng sa terata ea tšepe ea archwire e ne e le halofo feela ea boholo ba terata e sa hloekang. Lintho tse ntle tsa ho sisinyeha le ho monya ho ts'oenyeha ha archwire li bohlokoa ho bophelo bo botle le bophelo bo botle ba meno. Li-archwires tsa setso, joalo ka tšepe e sa hloekang, li ka eketsa ho monya ha metso.
