Nitinol Daim Ntawv Qhia
Nitinol yog cov duab-nco alloy nrog cov khoom zoo heev.
Koj tuaj yeem nqa ib daim ntawv ncaj nraim ntawm nitinol, khoov rau hauv lub voj voog ntawm koj txhais tes thiab yob nws hla lub rooj. Tom qab ntawd thaum koj khaws nws thiab pov rau hauv ib lub tais ntawm dej kub, nws yuav tam sim ntawd lub caij nplooj ntoos hlav rov qab mus rau nws qhov qub ncaj zoo nrog stunning ceev thiab quab yuam.
Nitinol tau pom thawj zaug hauv xyoo 1959 ntawm Naval Ordinance Laboratory uas cov kws ua haujlwm tau sib tw nrog kev tsim lub taub ntswg rau thawj submarine-launched nuclear ballistic missile. Ntawm lwm cov hlau uas tau raug tshuaj xyuas, nws tau pom tias cov khoom txias ntawm cov npib tsib xee-titanium alloy ua rau cov hlau lead zoo li lub suab nrov thaum lawv poob rau hauv av, tab sis cov pas tuav sov "zoo li lub tswb". Qhov no hinted ntawm ib yam dab tsi tshwm sim microscopically nyob rau hauv lub alloy nyob rau hauv ib tug tshwj xeeb txoj kev thiab ua rau lub discovery ntawm nws amazing pseudo-elasticity.
Qhov no tau muab nws txoj kev cia siab dav dav ntawm kev siv hluav taws xob zoo tshaj li lub qhov ntswg ntawm cov foob pob hluav taws nuclear, txawm tias nws lub npe hu ua harkens los ntawm lub hauv paus chiv keeb.
Nitinol yog qhov nyuaj heev los ua, vim qhov tshwj xeeb nruj kev sib xyaw ua ke yuav tsum tau ua, thiab qhov ua kom muaj zog ntawm titanium. Txhua lub atom ntawm titanium uas sib txuas nrog oxygen lossis carbon yog ib qho atom uas raug nyiag los ntawm NiTi lattice, yog li hloov cov muaj pes tsawg leeg thiab ua rau qhov kev hloov pauv kub qis dua. Muaj ob txoj hauv kev melting tseem ceeb siv niaj hnub no:
Nqus Arc Remelting (VAR)
Qhov no yog ua los ntawm kev tawm tsam hluav taws xob arc nruab nrab ntawm cov khoom siv raw thiab cov dej-txias tooj liab ntaus phaj. Melting yog ua tiav hauv lub tshuab nqus tsev siab, thiab cov pwm nws tus kheej yog dej-txias tooj liab.
Vacuum Induction Melting (VIM)
Qhov no yog ua los ntawm kev siv alternating magnetic teb kom sov cov ntaub ntawv raw hauv crucible (feem ntau carbon). Qhov no kuj ua tiav hauv lub tshuab nqus tsev siab.
Cov duab nco thiab superelasticity yog cov khoom tshwj xeeb tshaj plaws ntawm nitinol ntawv thiab phaj. Lub cim xeeb cov cuab yeej tso cai rau cov khoom siv "nco" nws cov duab qub thiab khaws nws thaum rhuab saum nws qhov kev hloov pauv-kub. Nws tshwm sim vim muaj cov qauv siv lead ua sib txawv ntawm nickel thiab titanium. Cov hlau pseudo-elastic no kuj qhia tau zoo kawg elasticity uas yog kwv yees li 10 mus rau 30 npaug ntau dua li cov hlau zoo tib yam.
Nitinol daim ntawv (los yog phaj) yog ib daim ntawv tshwj xeeb ntawm cov duab nco alloys vim nws cov duab tso cai rau kev tsim qauv ntxiv. Tsis zoo li cov xaim thiab lub raj, daim ntawv yog ob sab qauv, uas kov yeej cov txheej txheem tsim teeb meem. Ib daim ntawv tiaj tus nitnol ua rau cov neeg tsim qauv ua haujlwm uas tsis tuaj yeem ua tiav ntawm cov hlau lossis raj, xws li stamping, xuas nrig ntaus, thiab kos duab sib sib zog nqus. Nws kuj tseem muaj cov qauv tsim kom yooj yim tsis muaj nrog lwm cov ntaub ntawv - tsim cov khoom tiaj tus thiab tom qab ntawd tsim nws los ua cov khoom siv.
Peb cov ntawv nitinol thiab phaj tuaj yeem tsim nrog cov tuab tuab heev thiab cov tuab tuab tswj thoob plaws qhov chaw. Qhov kev muaj peev xwm ua tau zoo no tau txais txiaj ntsig zoo hauv cov txheej txheem kev ua kom zoo thiab automation - qhov pib tuab zoo ib yam, kev tswj xyuas tom qab ua tiav yuav ua rau qhov tseeb qhov ntev.
SSC muaj cov ntawv nitinol thiab phaj nrog cov ntsiab lus Af sib txawv, tso cai rau kev hloov kho ntawm cov hlau sib xyaw, kev kho cua sov, kev ua tiav saum npoo, thauj cov toj siab, thiab lub zog tensile.
Nitinol daim ntawv thiab phaj yog zoo tagnrho rau laser txiav, hluav taws xob paug machining (EDM), thiab yees duab etching, enabling cov creation ntawm cov ncauj lus kom ntxaws, me me scaled lug.
