Cov tooj liab-nickel{1}}titanium sputtering lub hom phiaj yog tsim los ntawm kev tswj cov alloying ntawm tooj liab, npib tsib xee, thiab titanium. Cov alloy ua rau cov khoom siv hluav taws xob zoo, zoo corrosion kuj, thiab muaj zog txhua yam. Vim hais tias ntawm cov khoom no, cov hom phiaj yog siv nyob rau hauv ntau yam kev lag luam, nrog rau optics, qhov twg nyias zaj duab xis coatings yuav tsum tau, electronics, qhov twg conductive txheej yuav tsum tau, cov ntaub ntawv kho kom zoo nkauj, qhov twg ib tug tiav yog muab, thiab nyob rau hauv mechanical qhov twg check thiab hnav - tiv taus coatings yog xav tau.
Cov kauj ruam ntawm Kev Npaj Copper -Nickel-Titanium Alloy Target
Kev npaj cov ntaub ntawv nkag: Siv tooj liab thiab npib tsib xee hauv daim ntawv phaj thiab titanium hauv daim txhuam cev, muaj purities ntau dua 99.9%. Tom qab ntawd, coj cov ntaub ntawv thiab ntsuas lawv raws li qhov xav tau ntawm cov hlau alloy, uas tuaj yeem ua tau (Cu: 50-70%, Ni: 20-30%, Ti: 10-20%, piv txwv li, Cu-30Ni-5Ti wt%).
Nqus Melting Txheej Txheem: Muab cov ntaub ntawv pib ntawm tooj liab, npib tsib xee thiab titanium rau hauv lub crucible nyob rau hauv cov piv txwv hais saum toj no. Txhawm rau kom ua tiav cov txiaj ntsig zoo dua, tso cov npib tsib xee thiab titanium (uas muaj cov ntsiab lus melting ntau dua) hauv qab no thiab muab tooj liab tso rau sab saum toj kom muaj peev xwm txawm tias melting. Tom qab ntawd, koj yuav tsum khiav tawm ntawm lub qhov cub kom ua tiav lub tshuab nqus tsev ntawm 10^-3 txog 10^-4 Pa, thiab tom qab ntawd rov ua dua nrog cov purity argon kom ua tiav qhov chaw tiv thaiv. Thaum kawg, qhov kub tau nce mus rau thaj tsam ntawm 1600-1800 degree. Txij li qhov no yog saum toj no lub melting point ntawm titanium (1668 degree), tag nrho cov hlau yuav molten tag. stirring yog nqa tawm ntawm electromagnetic los yog mechanical txhais tau tias kom homogenise yaj. Qhov kub yog tuav rau 10-20 feeb kom txo tau kev sib cais. Thaum kawg, cov hlau molten yog poured rau hauv preheated graphite los yog tooj liab pwm thiab tso cai rau txias, tsim ib tug khoom alloy ingot.
Homogeneous kev kho mob: Lub alloy ingot yog muab tso rau hauv ib lub thawv - hom kuj rauv thiab tuav ntawm 800-950℃(uas yog qis dua lub solidus kub ntawm lub alloy) rau 2-4 teev ntawm lub cub txias.
Kub ua haujlwm: Nws cov txheej txheem suav nrog cua sov homogenised alloy ingot mus rau qhov kub ntawm 700 txog 900 degrees Celsius. Nyob rau ntawm qhov kub ntawd, cov hlau yuav dhau los ntawm lub tshuab unidirectional forging los yog lub tshuab dov kom plastically deformed rau hauv lub hom phiaj billet.
Annealing kev kho mob: Nws cov txheej txheem ntawm cov billet muaj qhov sib npaug ntawm qhov kub ntawm 600 mus rau 750 degrees Celsius rau 1-2 teev, tom qab ntawd lub billet tuaj yeem ua cua sov lossis cua sov.
Machining: Lub hom phiaj billet mus dhau cov txheej txheem xws li ua, tig, thiab nto sib tsoo kom tau lub hom phiaj qhov ntev thiab qhov chaw tiav.
Kev siv tooj liab-nickel-titanium alloy phiaj
Electronics: Siv los ua txheej txheej txheej hauv cov yeeb yaj kiab nyias rau cov khoom siv hluav taws xob thiab cov khoom siv.
Optical coatings: siv rau ib feem ntawm kev tsim cov iav tsom iav thiab cov ntxaij lim dej.
Abrasion-cov tshuaj tiv thaiv: siv rau ntawm qhov chaw ntawm cov cuab yeej thiab pwm los muab cov txheej tiv thaiv tawv.
Decorative coatings: siv los txhim kho cov xov tooj ntawm tes, cov hniav nyiaj hniav kub thiab lwm yam khoom siv zoo nkauj nrog cov txheej tiv thaiv tawv.
Aerospace: Siv los muab cov txheej txheem ua haujlwm uas tiv taus oxidation siab thiab kub siab.
