Hlau Ua Npuas Ncauj - hlau ua pa

Vim nws cov qauv tshwj xeeb, nws muaj cov khoom tshwj xeeb hauv ntau yam. Raws li cov khoom siv, nws yog tus yam ntxwv ntawm lub teeb yuag thiab lub zog tshwj xeeb; Raws li cov khoom siv ua haujlwm, nws muaj ntau yam khoom siv lub cev xws li ntxeem tau, kev co damping, damping, suab-absorbing, suab rwb thaiv tsev, tshav kub dissipation, cuam tshuam lub zog nqus, electromagnetic shielding thiab lwm yam.
Ua npuas ncauj hlauyog npaj los ntawm hmoov metallurgy txoj kev thiab electroplating txoj kev, tus qub los ntawm kev ntxiv foaming tus neeg sawv cev rau molten hlau los ua npuas ncauj hlau; tom kawg los ntawm cov txheej txheem electrodeposition ntawm polyurethane ua npuas ncauj skeleton replicated rau hauv npaus hlau.
Hmoov metallurgy txoj kev los ua npuas hlau, yog ntxiv rau cov hmoov tshuab tshuab (xws li NH4Cl), sintering tus neeg sawv cev volatilization, tawm hauv pores. Ua npuas ncauj hlau nrog cov pores zoo li niaj zaus thiab porosity siab li 95% tuaj yeem ua los ntawm electrochemical deposition, nrog rau cov ntaub ntawv ua npuas ncauj nrog cov hlau thiab alloys xws li Cu, Ni, NiCrFe, ZnCu, NiCu, NiCrW, NiFe, thiab lwm yam hlau thiab alloys li cov cev pob txha. Cov hlau electrochemically tso rau ntawm lub cev ntxeem tau yog sintered kom cov khoom tso tawm tau txuas nrog tag nrho, thiab lub zog yog mus txog qhov yuav tsum tau ua npuas dej ua npuas hlau nrog siab porosity, uas tuaj yeem ntim nrog ntau yam khoom xws li catalysts thiab electrolytes hauv. siv.
Txhuas, npib tsib xee thiab lawv cov alloys tau siv ua npuas ncauj hlau, ntxiv rau, ua npuas ncauj tooj liab kuj muaj qee qhov chaw rau kev txhim kho.
Ua npuas ncauj aluminiumthiab nws cov alloys yog lub teeb yuag, nrog lub suab nqus, rwb thaiv tsev kub, kev co damping, nqus ntawm qhov cuam tshuam lub zog thiab electromagnetic tsis thiab lwm yam ntxwv, haum rau cov cuaj luaj, dav hlau thiab nws qhov chaw rov qab los ntawm kev cuam tshuam ntawm txheej tiv thaiv, tsheb buffers, hluav taws xob machinery kev co. damping li, mem tes zog electromagnetic yoj tiv thaiv npog.
Nickel ua npuas ncaujmuaj cov roj permeability siab, siab tshwj xeeb thaj chaw thiab capillary quab yuam vim nws txoj kev sib txuas pore qauv thiab porosity siab, thiab feem ntau yog siv los ua cov khoom siv ua kua lim dej, atomizers, catalytic converters, roj teeb electrode daim hlau thiab kub exchangers.
Tooj liab ua npuas ncaujconductivity thiab ductility yog qhov zoo, thiab tus nqi npaj qis dua nickel ua npuas ncauj, zoo conductivity, tuaj yeem siv rau kev npaj cov roj teeb tsis zoo electrode (carrier) cov ntaub ntawv, catalyst carriers thiab electromagnetic shielding cov ntaub ntawv. Hauv particular, tooj liab ua npuas ncauj rau roj teeb raws li cov khoom siv electrode substrate, muaj qee qhov zoo, tab sis vim qhov corrosion kuj ntawm tooj liab tsis zoo li npib tsib xee, yog li kuj txwv qee qhov ntawm nws daim ntawv thov.
Cov khoom no tau ntev tau siv los ua cov khoom tseem ceeb rau cov khoom siv dav hlau clamping. Hauv kev lag luam aerospace thiab foob pob hluav taws, tuaj yeem ua rau hauv cov khoom siv sandwich bearing, xws li rau lub tis hlau plhaub ntawm lub cev kev txhawb nqa, missile qhov ntswg lub khob hliav qab ntawm lub plhaub ntawm qhov kub thiab txias ntawm lub cev kev txhawb nqa (vim nws cov thermal zoo. conductivity) thiab tsaws iav ntawm lub spacecraft. Nyob rau hauv kev tsim kho, ua npuas ncauj hlau yog xav tau los ua lub teeb, tawv, hluav taws-resistant ntsiab, railings los yog txhawb lub cev rau cov khoom no. Lub high-frequency, high-ceev acceleration thiab deceleration ntawm niaj hnub elevators kuj yuav tsum tau lub teeb yuag nrog ob lub zog-absorbing thiab load-nqa cov khoom los txo lub zog noj. Cushioning kuj yog ib qho tseem ceeb ntawm kev siv cov hlau ua npuas ncauj, uas yuav tsum muaj peev xwm nqus tau lub zog thaum ua kom lub zog siab tshaj plaws ua rau cov khoom tiv thaiv qis dua qhov kev txwv ntawm kev puas tsuaj.
