Kev Siv Osmium Hlau Hauv Kev Lag Luam Electronics
Osmium yog ib qho ntawm cov hlau tsis tshua muaj nyob hauv lub ntiaj teb lub plhaub thiab yog ib feem ntawm pawg hlau platinum (PGM), nrog rau platinum, iridium, ruthenium, rhodium, thiab palladium. Cov khoom no muaj tus lej atomic 76 thiab paub txog nws cov khoom siv lub cev tshwj xeeb: qhov ceev heev, qhov chaw yaj siab, thiab kev tiv taus kev hnav thiab xeb zoo nyob rau hauv qee qhov xwm txheej. Txawm hais tias osmium tsis siv dav li lwm cov hlau xws li tooj liab, nyiaj, lossis kub, nws tseem muaj cov ntawv thov nthuav - tshwj xeeb tshaj yog thaum kev lag luam xav tau cov ntaub ntawv uas muaj kev ruaj khov thiab kev ua haujlwm ruaj khov.
Hauv kev lag luam hluav taws xob, osmium tsis tshua siv ua cov khoom siv tseem ceeb vim nws muaj tsawg, tus nqi siab, thiab kev nyab xeeb (tshwj xeeb tshaj yog cuam tshuam nrog cov tshuaj osmium uas tuaj yeem tsim cov tshuaj lom osmium tetroxide). Txawm li cas los xij, hauv qee daim ntawv thov uas xav tau lub zog kho tshuab thiab cov khoom siv tshuaj tshwj xeeb, osmium tuaj yeem yog cov khoom siv muaj txiaj ntsig. Nov yog qee qhov kev siv osmium hauv kev lag luam hluav taws xob, nrog rau cov laj thawj vim li cas nws thiaj xaiv thiab txhua qhov kev txwv.
1. Cov Khoom Siv Alloy rau Cov Hluav Taws Xob Uas Tiv Thaiv Tau
Cov khoom siv hluav taws xob feem ntau vam khom cov khoom siv hluav taws xob - cov khoom uas kov kom xa hluav taws xob, xws li cov hloov pauv, cov relays, cov connectors, lossis cov khoom sib txuas. Cov teeb meem loj tshaj plaws nrog cov khoom sib txuas hluav taws xob yog kev hnav vim kev sib txhuam, cua sov los ntawm arcing, thiab oxidation lossis kev ua qias tuaj ntawm qhov chaw, uas ua rau muaj kev tiv thaiv ntau ntxiv.
Osmium, tshwj xeeb tshaj yog nyob rau hauv daim ntawv alloy nrog lwm cov hlau PGM xws li iridium lossis platinum, pab txhawb rau:
- Kev tawv tawv heev kom qhov chaw sib cuag tsis lwj sai.
- Kev tiv thaiv kev hnav hauv cov ntawv thov uas muaj kev txav mus los rov ua dua.

2. Ua kom muaj kev tiv thaiv rau kev tawg ntawm Arcing
Hauv ib lub voj voog hluav taws xob uas muaj qee qhov tam sim no lossis voltage, thaum lub qhov qhib lossis kaw, lub arc hluav taws xob tuaj yeem tshwm sim. Lub arc no tuaj yeem "erode" qhov chaw sib cuag thiab hloov nws cov yam ntxwv: qhov chaw ua ntxhib, oxides tsim, thiab kev tiv thaiv nce ntxiv.
Cov ntaub ntawv uas tuaj yeem tiv taus kev tawg ntawm arc yog qhov xav tau kom tswj tau qhov kev ntseeg tau. Osmium muaj qhov zoo hauv cov hlau sib xyaw vim tias:
- Txo qhov nrawm ntawm kev yaig ntawm qhov chaw sib cuag.
- Tswj tau qhov chaw ruaj khov tiv thaiv kev hnav ntau zaus.
Txawm hais tias nyob rau hauv kev lag luam niaj hnub no, cov hlau alloys uas yog nyiaj, tungsten, lossis ruthenium feem ntau siv rau ntau hom relays thiab switches, osmium tseem ceeb ua ib qho khoom siv rau cov xwm txheej hnyav, tshwj xeeb tshaj yog thaum kev tiv thaiv kev hnav thiab kev ruaj khov yog qhov tseem ceeb tshaj plaws.
3. Txheej rau Cov Cheebtsam Me Me uas Muaj Kev Ruaj Ntseg Siab
Hauv ntiaj teb ntawm cov khoom siv hluav taws xob precision—piv txwv li, hauv cov khoom siv microelectromechanical (Micro-Electro-Mechanical Systems / MEMS), qee cov khoom siv sensor, thiab cov txheej txheem me me uas txav mus los—cov txheej txheem saum npoo av yog qhov tseem ceeb los txo kev sib txhuam, kev hnav, thiab kev hloov pauv ntawm cov khoom vim yog ib puag ncig.
Hauv kev xav, osmium tuaj yeem siv ua cov khoom siv txheej vim tias:
- Nyuaj heev thiab tuaj yeem ua rau qhov tsis kam ntawm qhov chaw.
- Tiv taus kev txhuam, tsim rau cov khoom me me uas muaj kev sib cuag nrog tshuab.
Txawm li cas los xij, kev siv osmium ua ib txheej txheej tsis tshua muaj thiab feem ntau ua tau zoo dua los ntawm cov ntaub ntawv txheej txheej uas siv tau zoo dua xws li nitride (TiN), carbon xws li DLC (pob zeb diamond zoo li carbon), lossis lwm yam PGM alloys uas muaj kev nyab xeeb dua thiab yooj yim dua rau kev ua. Txawm li cas los xij, hauv kev tshawb fawb txog cov ntaub ntawv lossis cov ntawv thov tshwj xeeb, osmium yuav yog tus neeg sib tw vim nws cov khoom siv kho tshuab zoo dua.
4. Cov Cheebtsam ntawm Cov Cuab Yeej Hluav Taws Xob Precision thiab Cov Khoom Siv Tshwj Xeeb
Ua ntej txoj kev loj hlob sai ntawm cov thev naus laus zis semiconductor thiab cov khoom siv niaj hnub no, qee cov khoom siv precision siv cov hlau PGM rau cov khoom uas xav tau kev ruaj khov thiab kev ua haujlwm ntev. Osmium ib zaug tau paub txog nws siv rau hauv cov khoom uas muaj kev sib cuag zoo thiab cov txheej txheem precision.
Hauv kev siv hluav taws xob, cov kev siv xws li:

Ntau daim ntawv thov hluav taws xob tuaj yeem ua tau raws li cov lus qhia nrog lwm cov ntaub ntawv: kub rau kev ua hluav taws xob thiab kev tiv thaiv xeb, nyiaj rau kev ua hluav taws xob siab, tungsten rau kev tiv thaiv cua sov, thiab ruthenium / rhodium rau qee hom kev sib cuag. Yog li ntawd, osmium feem ntau tsuas yog siv thaum cov kev cai ua haujlwm tshwj xeeb tau ua tiav tiag tiag.
7. Kev cia siab rau Osmium hauv Cov Khoom Siv Hluav Taws Xob Niaj Hnub
Txij no mus, osmium yuav tseem yog ib yam khoom tshwj xeeb, tsis yog ib yam khoom tseem ceeb. Txawm li cas los xij, muaj peev xwm txuas ntxiv mus xav txog nws hauv:
- kev sib cuag alloy rau kev siv hnyav heev,
– kev tshawb fawb txog qhov chaw thiab tribology (kev tshawb fawb txog kev sib txhuam thiab kev hnav) ntawm cov khoom me me,
- cov ntawv thov niche uas xav tau qhov siab tshaj plaws mechanical durability.
Nrog rau qhov xav tau ntau ntxiv rau cov khoom siv ruaj khov, kev ua kom me me, thiab cov tshuab hluav taws xob ua haujlwm hauv cov chaw muaj kev nyuaj (piv txwv li, kev lag luam hnyav, kev tiv thaiv, lossis kev tshawb nrhiav), kev txaus siab rau cov ntaub ntawv ua tau zoo - suav nrog osmium - tej zaum yuav tseem ceeb, tshwj xeeb tshaj yog nyob rau hauv daim ntawv ntawm cov hlau lossis cov yeeb yaj kiab nyias.
Xaus
Osmium yog ib hom hlau tsis tshua muaj nrog cov khoom siv kho tshuab thiab thermal zoo heev, ua rau nws muaj txiaj ntsig zoo hauv kev lag luam hluav taws xob, tshwj xeeb tshaj yog rau cov ntawv thov uas xav tau kev tiv thaiv kev hnav, kev ruaj khov kub siab, thiab kev tiv thaiv kev tawg. Osmium ua rau muaj kev nkag siab zoo tshaj plaws hauv cov hlau sib xyaw rau kev sib cuag hluav taws xob, cov khoom siv precision, thiab ua kev txhawb nqa rau kev tshawb fawb txog cov ntaub ntawv.
Txawm li cas los xij, nws siv yog txwv los ntawm qhov tsis txaus, tus nqi, kev ua tiav nyuaj, thiab kev txhawj xeeb txog kev nyab xeeb cuam tshuam nrog cov tshuaj osmium tetroxide. Vim li no, osmium tsis tshua siv rau hauv cov khoom siv hluav taws xob loj, tab sis tseem ceeb ua qhov kev daws teeb meem tshwj xeeb rau cov kev xav tau kev ua tau zoo heev.
Yog tias koj xav tau, kuv tuaj yeem ntxiv ib ntu "piv txwv thov hauv cov khoom siv tiag tiag" (kev lag luam relays, precision switches, lossis cov connectors tshwj xeeb) lossis sau ua ke ib qho kev kawm ntxiv ntawm tsab xov xwm ua tiav nrog cov ntaub ntawv thiab cov lus hais.
