Lub hom phiaj yog cov khoom siv hauv kev sim kev tshawb fawb, kev ua lag luam lossis lwm yam kev siv, feem ntau los nqus, cuam tshuam lossis hloov cov kev taw qhia thiab cov khoom ntawm cov khoom ntws, rays lossis electromagnetic tsis. Hom hom muaj xws li cov hom phiaj hlau, cov hom phiaj ceramic, cov hom phiaj alloy thiab cov hom phiaj sib xyaw. Txhua hom muaj nws tus kheej tshwj xeeb lub cev thiab tshuaj lom neeg thiab tsim nyog rau cov xwm txheej sib txawv.
1.Kab cais
(1) Cov hom phiaj hlau
Nws yog dav siv vim nws zoo heev hluav taws xob thiab thermal conductivity. Xws li tooj liab, txhuas, titanium, thiab lwm yam, feem ntau siv hauv electron beam evaporation thiab sputtering txheej tshuab.
(2) Cov khoom siv ceramic
Ceramic lub hom phiaj yog nyiam rau lawv qhov siab melting point, corrosion kuj thiab tshuaj stability. Xws li alumina, silicon nitride, dav siv nyob rau hauv kub kub thiab corrosive ib puag ncig.
(3) Cov khoom siv alloy
Los ntawm kev sib txuas cov ntsiab lus hlau sib txawv, cov hom phiaj alloy ua ke cov txiaj ntsig zoo ntawm ntau yam hlau. Xws li stainless hlau, tooj dag, rau kev siv hluav taws xob lossis kho qhov muag.
(4) Cov khoom siv sib xyaw ua ke
Hom phiaj no ua tiav cov khoom zoo tag nrho los ntawm kev sib txuas ob lossis ntau cov ntaub ntawv. Piv txwv li, carbon nanotube-reinforced composites, yog siv nyob rau hauv high-strength, lub teeb yuag daim ntaub ntawv.
(5) Lub ntiaj teb tsis tshua muaj thiab cov khoom siv tshwj xeeb lub hom phiaj:
Cov hom phiaj no yog siv rau kev siv tshwj xeeb vim lawv lub cev thiab tshuaj lom neeg tshwj xeeb. Xws li lub ntiaj teb tsis tshua muaj caij neodymium, siv hauv kev tsim cov alloys tshwj xeeb thiab cov khoom sib nqus muaj zog.
2. Cov txheej txheem npaj

Daim ntawv thov: Feem ntau yog siv rau kev npaj cov hom phiaj hlau, xws li tooj liab, txhuas thiab lwm yam.
Cov txheej txheem: suav nrog cua sov cov khoom siv saum toj no lub melting point thiab ces txias nws raws li ib tug tshwj xeeb txias txheej txheem los tsim tus yam siv lead ua qauv.
Nta: Cov khoom loj tuaj yeem ua tiav, tab sis qhov txias ceev thiab ib puag ncig yuav tsum tau tswj nruj me ntsis kom tiv thaiv cov khoom tsis xws luag.
(3) Chemical Vapor Deposition (CVD)
Daim ntawv thov: Siv los npaj cov phiaj xwm nyias, xws li silicon zaj duab xis, hlau oxide zaj duab xis, thiab lwm yam.
Cov txheej txheem: Ib zaj duab xis homogeneous yog tsim rau ntawm substrate los ntawm cov tshuaj tiv thaiv.
Nta: Lub thickness thiab muaj pes tsawg leeg ntawm cov zaj duab xis yuav raug tswj kom raug, tab sis cov cuab yeej thiab cov txheej txheem yog complex.
(4) Lub cev Vapor Deposition (PVD)
Daim ntawv thov: Nws kuj yog tsim rau kev npaj ntawm nyias zaj duab xis lub hom phiaj, tshwj xeeb tshaj yog hlau thiab alloy films.
Txheej txheem: Lub cev txoj kev (xws li sputtering los yog evaporation) tsim ib zaj duab xis nyias ntawm lub substrate.
Qhov zoo: Haum rau kev npaj cov khoom siv purity siab, tuaj yeem ua tiav cov yeeb yaj kiab zoo tswj tau zoo.
(5) Laser txoj kev siv tshuab
Innovation: Kev npaj cov hom phiaj rau cov duab thiab cov qauv, tshwj xeeb tshaj yog nyob rau hauv prototyping thiab me me series ntau lawm.
Qhov zoo: Siab precision thiab yoog raws los tsim cov hom phiaj ncaj qha los ntawm cov qauv hauv computer.
(6) Electrochemical txoj kev
Daim ntawv thov: Haum rau lub hom phiaj npaj ntawm cov hlau tshwj xeeb thiab alloys.
Nta: Cov khoom yog tso los ntawm cov txheej txheem electrolytic, uas tuaj yeem nqa tawm ntawm qhov kub thiab txias, uas yog qhov tsim nyog rau kev tswj cov tshuaj purity ntawm cov khoom.
Kev xaiv lub hom phiaj zoo yuav tsum tau xav txog ntawm daim ntawv thov scenario, qhov yuav tsum tau muaj lub cev thiab tshuaj lom neeg lub cev, thiab tus nqi siv tau. Cov qauv tam sim no yog txhawm rau txhim kho qhov purity thiab uniformity ntawm lub hom phiaj cov khoom, txo qhov kev tsim khoom tsis xws luag, thiab txhim kho ntau tus phooj ywg ib puag ncig thiab kev npaj cov nqi. Peb lub tuam txhab tuaj yeem muab cov hom phiaj siab purity hlau lossis lwm lub hom phiaj alloy, yog tias koj xav tau, thov xa email rau peb.
