Hauv kev tswj hluav taws xob niaj hnub thiab lub zog xa hluav taws xob, kev sib cuag hluav taws xob ua lub luag haujlwm tseem ceeb hauv kev tsim thiab tawg circuits; yog li ntawd, lawv qhov kev ua tau zoo ncaj qha txiav txim siab tag nrho kev ntseeg siab thiab kev pabcuam lub neej ntawm tag nrho cov cuab yeej. Kev Sib Txuas Sib Txuas tau tshwm sim los ua kom tau raws li qhov xav tau tseem ceeb no; nws yog ib lub cermet los yog hmoov metallurgy los ua ke ua los ntawm kev sib txuas ob lossis ntau cov khoom sib txawv ua ke los ntawm cov txheej txheem tsim khoom tshwj xeeb. Qhov kev tsim kho tshiab no dhau qhov kev txwv lub cev ntawm ib leeg - cov khoom siv hlau, tsis yog tsuas yog txhim kho kev ua tau zoo ntawm - xws li kev tiv thaiv arc yaig thiab hluav taws xob conductivity -tab sis kuj txo qis kev noj cov khoom muaj txiaj ntsig zoo. Piv txwv li, Composite Contact Rivets rau Relays- tau siv dav thoob plaws ntau yam kev tswj cov cuab yeej siv hluav taws xob- ua piv txwv zoo tshaj qhov kev ruaj ntseg tshwj xeeb uas pom los ntawm cov ntaub ntawv sib xyaw nyob rau hauv siab - zaus hloov pauv.
Kev sib txawv ntawm cov txheej txheem npaj yog qhov tseem ceeb hauv kev txiav txim siab qhov kawg ntawm kev sib cuag hluav taws xob. Tam sim no, cov txheej txheem kev npaj tseem ceeb suav nrog cov hmoov hlau metallurgy, sab hauv oxidation, thiab thermal spraying. Ntawm cov no, hmoov metallurgy- uas suav nrog kev ua cov ntaub ntawv tsis raug rau hauv cov hmoov thiab sintering rau hauv cov khoom sib xyaw ua ke- ua cov txheej txheem hauv paus rau kev tsim cov khoom siv refractory pseudo- alloys xws li tooj liab -tungsten thiab nyiaj-tungsten. Hauv qhov sib piv, cov nyiaj ib txwm muaj -cadmium hluav taws xob tiv tauj feem ntau yog tsim los ntawm txoj kev oxidation sab hauv. Txawm hais tias cov khoom no muaj kev tiv thaiv zoo heev rau arc yaig, kev txhawj xeeb txog kev ua qias tuaj ib puag ncig ua rau kev lag luam maj mam hloov mus rau qhov tshiab, ntau dua eco-tus phooj ywg oxide systems.
Raws li kev cai ib puag ncig dhau los ua nruj zuj zus, kev tshem tawm cadmium tau tshwm sim los ua ib qho tseem ceeb hauv kev lag luam. Ib zaug - tseem ceeb nyiaj- cadmium oxide (AgCdO) cov hluav taws xob tiv tauj tau maj mam hloov los ntawm eco- lwm txoj kev phooj ywg xws li nyiaj- tin oxide (AgSnO₂) thiab nyiaj - tooj liab oxide. Txawm li cas los xij, hauv kev sib zog los txo cov nqi tsim khoom thiab txuag cov peev txheej nyiaj, ntau lub tuam txhab tseem cog lus los txhim kho cov qauv bimetallic. Piv txwv li, AgCdO bimetal silver rivet tiv tauj uas tsim los siv cov khoom txias siab heev-kev siv tshuab taub hau ua tiav qhov sib npaug ntawm kev ua tau zoo thiab tus nqi- kev ua tau zoo los ntawm kev sib koom ua ke siab heev -kev ua haujlwm txheej txheem mus rau qis- tus nqi tooj liab substrate.
Ntawm ntau cov bimetallic sib xyaw ua ke, kev sib koom ua ke ntawm cov nyiaj thiab tooj liab yog qhov nyiam heev vim lawv cov khoom zoo sib xws. Copper muaj superior hluav taws xob conductivity thiab formability, muab tus contactor nrog ib tug ruaj khov tam sim no txoj kev thiab cov qauv kev them nyiaj yug, thaum lub silver alloy txheej yog lub luag hauj lwm rau xa tshwj xeeb kuj rau arc yaig. Cov nyiaj zoo ib yam- tooj liab sib xyaw rivet tiv tauj feem ntau pom nyob rau hauv riveted los yog laminated configurations; metallurgical bonding- feem ntau ua tiav los ntawm cov txheej txheem xws li diffusion vuam- ua kom muaj kev sib cuag ruaj khov nyob rau hauv siab - cov xwm txheej tam sim no. Tsis tas li ntawd, cov nyiaj no -cadmium oxide bimetal contact rivets tseem ua lub luag haujlwm tseem ceeb hauv cov ntawv thov hloov pauv tshwj xeeb.
Tshaj li qhov yuav tsum tau muaj rau hluav taws xob conductivity, tus qauv tsim ntawm cov hluav taws xob tiv tauj yuav tsum tau hais txog qhov xav tau ntawm kev hnav tsis kam thiab corrosion kuj. Nyob rau hauv cov ntaub ntawv siv tau-txawm yog nyob rau hauv ib puag ncig ntub los yog kev lag luam chaw raug corrosive gases- siab- zoo bimetal hu rivets tsis tu ncua tuav tsis tshua muaj kev tiv thaiv thiab xyuas kom ruaj ntseg teeb liab kis tau tus mob. Nyob rau tib lub sijhawm, rau cov ntawv thov uas cuam tshuam nrog kev sib cuag nrog kev sib txhuam tsis tu ncua, engineers feem ntau xaiv rau AgNi bi-hlau hluav taws xob nyiaj tiv tauj-tshwj xeeb yog cov alloyed nrog npib tsib xee- los txhim kho cov khoom hnav tsis kam thiab lub zog txhua yam.
Nyob rau hauv cov txheej txheem tsim tshwj xeeb, precision riveting cov txheej txheem yog qhov tseem ceeb tshaj plaws. Kev paub tab bi-hlau Ag/Cu nyiaj sib cuag riveting txheej txheem tsis tsuas yog ua kom cov khoom sib xws tab sis kuj ua tau raws li qhov xav tau ntawm loj- nplai automated los ua ke. Tsis tas li ntawd, nyob rau hauv lub tshuab nqus tsev hloov uas yuav tsum tau tshwj xeeb arc siab heev - tawg peev xwm, tus tsim ntawm bi-hlau nyiaj tiv tauj feem ntau xav tau kev koom ua ke ntawm magnetic teb tswj technologies tsav lub arc mus rau hauv siab -kev sib hloov ceev, yog li txo kev sib cuag yaig.
Rau cov neeg siv kawg, xaiv cov ntsiab lus hluav taws xob tsim nyog rau cov keyboards yog qhov yuav tsum tau ua ua ntej kom ntseeg tau lub sijhawm ntev -, kev saib xyuas- ua haujlwm dawb ntawm lawv cov khoom siv. Tsis tas li ntawd, nyob rau hauv lub realm ntawm miniaturized thiab siab -precision electronic control systems, lub compact tab sis sophisticated khawm bimetal rivet hluav taws xob hu ua lub luag hauj lwm tseem ceeb nyob rau hauv lub meej kis tau tus mob ntawm hluav taws xob teeb liab. Hauv cov ntsiab lus, kev paub txog cov khoom siv thev naus laus zis sib xyaw ua ke thiab cov txheej txheem tsim khoom yog nyob ntawm qhov tseem ceeb ntawm kev tsim cov qib siab - zoo bimetal hluav taws xob rivet hu.
Yog tias koj muaj lus nug txog kev xaiv cov khoom siv raubimetal hluav taws xob rivet tiv tauj, los yog koj xav tau kev txhim kho kev daws teeb meem, thov tsis txhob yig tiv tauj peb; peb npaj txhij los muab koj nrog cov kws tshaj lij kev txhawb nqa thiab kev daws teeb meem.
