Shape Memory Alloy Manufacturing E nolofalletsa Likopo tse fapaneng tsa indasteri

Thepa e ikhethang ea TiNi-02 nickel-titanium alloy terata etsa hore e be thepa e khahlang ea khetho bakeng sa lihlahisoa tsa tlhahiso le likarolo tsa indasteri tse fapaneng.

Aerospace Lefapheng la sepakapaka, li-alloys tsa mohopolo oa sebopeho li sebelisoa ho etsa meralo e bobebe, e khutsitseng le e sebetsang hantle: lintlha tsena tse tharo - ho otloloha ke ntlha ea moralo oa sefofane. Likarolo tse kang li-nozzles tsa fan tse feto-fetohang, li-shock absorber, le li-actuator li entsoe ka lisebelisoa tsa alloy memory. Lisebelisoa tsena li na le lithempereichara tse tloaelehileng 'me li fetoha ka matla (le sebopeho se lakatsehang) ha li pholile ka lebaka la liphetoho tsa mocheso tse bakoang ke moea o potolohileng sefofane kapa liphetoho tsa mocheso o potolohileng nakong ea sefofane se tloaelehileng. Liphetoho tsa mocheso tse bakang phetoho ea mohato li ka hlahisoa ka litsela tse fapaneng, ebang ke karolo ea elektronike e futhumatsang sesebelisoa sa SMA kapa ka moea o feteletseng likarolong tse ling tsa sefofane. Mohlala oa lisebelisoa tsa mohopolo oa sebopeho tse sebelisoang ho nts'etsopele ea lifofane.

Tlhahiso ea morao-rao ea theknoloji ea lisebelisoa tsa memori ea sebopeho ke theknoloji ea deformation ea mapheo. Li-alloys tsa memori tsa sebopeho li ne li sebelisoa ho hlahisa lepheo le feto-fetohang le fetohang le ho fetola sebopeho nakong ea sefofane.

Koloi:

Likoloi tse fatše li boetse li rua molemo ho li-alloys tsa memori ea sebopeho, empa ts'ebeliso ea tsona e bonolo ebile e bonolo ho e sebelisa ho feta ho e tšoara. Ka mohlala, likoloi tse ling li na le li-valve tsa motsoako oa memori bakeng sa mekotla ea moea litulong, 'me tlas'a khatello e itseng, tšehetso ea lumbar setulong e ka lekana hantle le thekeng la mokhanni kapa mopalami. Ho feta moo, li-alloys tsa memori ea sebopeho li sebelisetsoa ho etsa li-actuator tse etsang hore likutu tsa koloi li koalehe habonolo, hammoho le li-valve ho laola lerata le ho thothomela ka enjene (e leng letšoao la bohlokoa la ts'ebetso indastering ea likoloi), ho ntlafatsa lerata, ho thothomela le ho thothomela ha Acoustic.

Mekhoa ea ho haha:

Sebaka se seng sa ts'ebeliso ea li-alloys tsa memori ea sebopeho ke moralo oa meralo. Mohlala, lithupa tsa SMA ka maballo a konkreite li thusa ho hatella marokho kapa meaho. Ka tekanyo e nyane, terata ea nitinol ea TiNi-02 e ka sebelisoa ho matlafatsa ts'epahalo ea lisebelisoa tsa liphaephe lits'ebetsong tsa liphaephe.

Meriana:

Tšebeliso ea li-alloys tsa memori ea sebopeho ho biomedicine e ka fokotsa tlhokahalo ea litšebetso tsa bongaka bakeng sa bakuli. Ka mohlala, li-stents tsa bongaka li ka kenngoa methapong ho ntlafatsa phallo ea mali ho bakuli ba nang le lefu la pelo ka mokhoa o fokolang haholo. Li-microactuators le mesifa ea maiketsetso li itšetlehile ka li-alloys tsa memori ho theha litho tsa maiketsetso tse thusang batho ba khaotsoeng ho tsamaea ka bolokolohi. Li-stents tsa pelo ke mokhoa o fokolang oa kalafo ea pelo, hangata o entsoe ka lisebelisoa tsa mohopolo oa sebopeho. (Tlhokomeliso: Setšoantšo se nkiloe tabeng ea thuto ea deformation ea polasetiki nakong ea katoloso ea stent ea biomedical, e se nang li-alloys tsa memori ea sebopeho, 'me e mona feela ho bontša ts'ebeliso e boletsoeng ka holimo). Ka tekanyo e nyane, li-alloys tsa mohopolo oa sebopeho li boetse li sebelisoa ho orthodontics, joalo ka li-braces; le optometry, joalo ka likhalase. Haeba foreimi e entsoe ka thepa ea mohopolo oa sebopeho, ha e hloke ho nkeloa sebaka leha e ka kobeha, o ka futhumatsa foreimi ho e khutlisetsa sebopeho sa eona sa pele.

Khamphani ea Baoji Freelong e ikemiseditse ho hodisa tshebediso ya boleng bo phahameng ba terata ya alloy ya TiNi-02 nickel-titanium. TiNi-02 nickel-titanium alloy terata eo re e hlahisang e netefatsa boleng le ts'ebetso e ntle haholo. Rea u amohela ho sebelisana le uena.
