Silver Contact Brazed Assemblies vam khom nyuaj rau kev koom nrog cov nyiaj alloy tiv tauj cov lus qhia nrog tooj liab lossis tooj liab alloy substrates. Kev sib koom ua ke zoo ntawm cov rooj sib txoos brazed feem ntau yog txiav txim siab los ntawm brazing muab tub lim hlau muaj pes tsawg leeg, melting kub ntau thiab deg oxide tshem tawm thaum lub sij hawm brazing. Kev xaiv tsis raug ntawm cov khoom siv brazing yuav ua rau cov pob qij txha nkig, nce kev tiv thaiv thiab kev ua tsis tiav thaum ntxov ntawm relays thiab contactors nyob rau hauv cyclic hluav taws xob load.
Brazing yog ib txoj kev sib koom ua ke mus tas li rau cov khoom sib xws lossis cov khoom sib txawv. Tsis zoo li fusion vuam thiab siab vuam, brazing ua haujlwm hauv qab lub melting point ntawm lub hauv paus hlau. Cov txheej txheem tsim cov pob qij txha du, txwv kev hloov pauv mus rau substrate microstructure thiab tswj workpiece qhov tseeb qhov tseeb. Cov yam ntxwv no ua rau brazing haum rau kev sib koom ua ke ntawm cov hlau- mus rau- hlau sib dhos, dav siv hauv aerospace, nuclear, instrumentation, electronics thiab hluav taws xob cov khoom tsim.
Brazing cov ntaub ntawv muaj xws li brazing muab tub lim hlau thiab brazing flux. Brazing muab tub lim hlau ua raws li cov khoom sib xyaw ua kom sib koom ua ke. Brazing flux tshem tawm oxides ntawm lub hauv paus hlau thiab muab tub lim hlau thiab tiv thaiv hlau substrates thaum cua sov. Filler hlau khoom thiab interfacial kev sib cuam tshuam nrog cov hlau hauv paus dominate zaum kawg kev sib koom ua haujlwm. Rau kev tswj hwm tus nqi, cov khoom siv hlau ua kom txo qis kev siv cov hlau muaj txiaj ntsig thaum ua tau raws li kev xav tau ntawm txhua yam, thermal thiab hluav taws xob.
Filler hlau yog categorized los ntawm alloy matrix. Cov qib feem ntau suav nrog tin-raws li, nyiaj-raws li, tooj liab-raws li, aluminium-raws li, npib tsib xee-raws li, manganese-raws li thiab muaj txiaj ntsig zoo hlau muab tub lim. Los ntawm melting kub, muab tub lim hlau muab faib ua mos solders nrog melting cov ntsiab lus hauv qab 450℃thiab hard brazing fillers saum toj no 450 degree. Hard brazing fillers tau muab faib ua qib siab - qib siab tshaj 900℃thiab nruab nrab- qib kub hauv qab 900℃. Filler hlau yog tsim rau hauv cov xov hlau, strips, rings, nplooj ntawv, foils, hmoov thiab muab tshuaj txhuam kom phim cov txheej txheem sib txawv. Muab tshuaj txhuam cov hlau ua ke cov hmoov hlau nrog cov nqa khoom xws li flux, hnyav thiab activators.
Silver-raws li brazing muab tub lim hlau yog siv dav siv tawv brazing alloy rau Brazed Silver Contact Assembly. Silver-raws li cov hlau muab tub lim muaj qhov nruab nrab melting ntau, zoo wettability, siab tensile zog, ductility, thermal conductivity, hluav taws xob conductivity thiab corrosion kuj. Nws tuaj yeem ua cov hlau me me, cov qauv hlau, cov hlau tsis muaj steel, siab - kub alloys, tooj liab alloys, Kovar alloys thiab refractory hlau. Copper, zinc, tin thiab cadmium yog ntxiv raws li cov ntsiab lus alloying. Tooj liab ua tus thawj additive los txo cov melting kub yam tsis tsim nkig intermetallic theem. Cov ntaub ntawv muaj xws li hlau, ntawv, nplhaib, ntawv ci sawb, muab tshuaj txhuam, preform, sandwich shim thiab cored hlau, txuam automated thiab phau ntawv brazing kab rau hluav taws xob tiv tauj ntau lawm.
Ntiaj teb no brazing khoom tso zis yog dominated los ntawm domestic ntau lawm. Ib pawg ntawm cov qib brazing ncav cuag cov qauv tsim khoom thoob ntiaj teb. Kev lag luam ntsib qhov tsis sib xws: qis- qib muab tub lim hlau muaj peev xwm tshaj li kev lag luam xav tau, thaum siab - cov khoom siv brazing kev ua tau zoo rau kev tsim khoom tsis txaus. Ntau qhov siab - kub muab tub lim hlau, active brazing alloys, automated brazing fillers, composite fillers, thiab paste brazing cov ntaub ntawv tseem cia siab rau imports. Cov khoom lag luam hauv tsev muaj nyob rau hauv melting thiab kev tswj xyuas. Feem ntau cov teeb meem muaj xws li cov tshuaj tsis sib xws, cov pa roj thiab cov ntsiab lus impurity, qhov seem tawm - ntawm - kev kam rau siab, thiab qhov chaw tsis zoo. Cov qauv kev lag luam sib txawv, thiab kev tswj hwm tsis sib haum, ua rau cov khoom tsis ruaj khov.
Rau cov ntawv siv hluav taws xob thiab cov khoom siv hluav taws xob, cov khoom siv hluav taws xob siv hluav taws xob siv titanium, zirconium, lossis niobium ua cov khoom siv. Cov hlau no cuam tshuam nrog cov chaw ceramic thiab tsim cov txheej txheem sib txuas ntawm cov ceramic thiab hlau substrates. Active brazing fillers yog tsim rau oxide ceramics, tsis yog -oxide ceramics, thiab inorganic dielectric cov ntaub ntawv. Tin-raws li cov muag muag muag tau dav siv rau kev sib txuas hauv hluav taws xob. Tin-raws li alloys muaj kub melting tsawg thiab ntau raw khoom reserves. Lawv tsim cov khoom siv hluav taws xob, thermal, thiab hluav taws xob sib txuas sib txuas rau tooj liab, tooj liab alloy, carbon steel, tin-plated, thiab zinc-plated substrates. Lead{11}}dawb thiab halogen{12}} dawb tin solder tau hloov cov hlau lead- uas muaj cov khoom siv rau kev ua raws li ib puag ncig, txawm hais tias kev ua tau zoo tag nrho tsis tuaj yeem ua tau raws li cov tsoos tins - txhuas txhuas.
