Muaj ob lub ntsiab lus ntawm tungsten alloy: dav tungsten alloy thiab nqaim tungsten alloy: Cov khoom siv hlau uas muaj tungsten yog sib sau ua ke hu ua tungsten alloys, xws li tungsten-hlau alloy, tungsten-copper alloy, tungsten-nickel alloy, thiab lwm yam. tungsten nqaim alloy: cov khoom siv alloy muaj li ntawm tungsten raws li cov khoom siv hauv paus (xws li 85% ~ 99% tungsten) thiab ib qho me me ntawm npib tsib xee (Ni), tooj liab (Cu), hlau (Fe), cobalt (Co), molybdenum ( Mo), chromium (Cr) thiab lwm yam hlau binders, tseem hu ua high-density tungsten alloy los yog high-density tungsten alloy los yog hnyav alloy [1]. Qhov ceev ntawm tungsten alloy tuaj yeem ncav cuag 16.5 ~ 19.0 g / cm^3. Feem ntau siv yog: W-Ni-Cu thiab W-Ni-Fe ob series. Cov khoom no muaj cov yam ntxwv tseem ceeb hauv lub cev xws li qhov ntom ntom, lub zog, hardness, ductility, hluav taws xob conductivity / thermal zog thiab yog li siv dav hauv kev tiv thaiv. Kev lag luam, kev lag luam aerospace, kev lag luam kho mob, kev lag luam hluav taws xob thiab lwm yam kev lag luam tuaj yeem muab faib ua ob lub ntsiab, W-Ni-Cu thiab W-Ni-Fe, nrog rau W-Ni-Cr, W-Ni-Mo. , W-Ni-Co thiab lwm yam alloys raws li lawv muaj pes tsawg leeg. Kev ua haujlwm ntawm tungsten alloys.
Lub cev thiab txhua yam khoom ntawm tungsten alloys yog cov nram qab no cuaj yam.
High density: Qhov ceev ntawm high-density tungsten alloys feem ntau yog 16.5 ~ 19.0 g / cm^3, uas yog ntau tshaj ob npaug ntawm cov hlau.
Lub zog tensile siab: Lub zog tensile ntawm high-density sintered W-Ni-Fe alloy yog 800 ~ 1000MPa, thiab nws lub zog tuaj yeem nce mus rau 1300 ~ 1500MPa tom qab kev kho cua sov thiab deformation ua.
Zoo ductility: W-Ni-Fe high-density alloy muaj zoo ductility thiab nws elongation nyob rau hauv sintered lub xeev muaj peev xwm ncav cuag 10% ~ 15%. Tom qab lub tshuab nqus tsev lossis cua dehydrogenation kho, qhov elongation tuaj yeem nce mus rau 20% ~ 30%.
Muaj peev xwm nqus tau hluav taws xob zoo: Lub peev xwm ntawm high-density alloy kom nqus tau hluav taws xob yog 30% mus rau 40% siab dua cov hlau lead, thiab nws qhov ruaj khov kuj zoo dua li cov hlau lead.
Cov khoom siv hluav taws xob zoo: High-density W-Ni-Cu thiab W-Ni-Fe alloys muaj cov khoom siv hluav taws xob zoo, xws li hluav taws xob zoo, kev tiv thaiv corrosion thiab siab voltage.
Zoo thermal conductivity thiab tsis tshua muaj linear expansion coefficient: Nws thermal conductivity yog 5 npaug ntawm stamped steel thiab nws linear expansion coefficient tsuas yog 1/2 ~ 1/3 ntawm hlau los yog hlau.
Zoo corrosion kuj thiab oxidation kuj.
Zoo weldability: High-density alloys tuaj yeem welded nrog tooj liab thiab nyiaj solders thiab tuaj yeem electroplated.
Zoo machining zog: Txij li thaum high-density W-Ni-Fe alloy muaj zoo ductility, nws yuav tsum machined los ntawm tig, milling, npaj, threading thiab threading, thiab kuj yuav raug rau loj deformation ntxiv dag zog rau kev kho mob xws li dov, teb forging. thiab Forging. Kev siv cov tungsten alloys.
Nws yog tsuas yog siv nyob rau hauv cov nram qab no yam ntawm tej-edge science thiab technology, xws li kev lag luam aerospace.
1. Gyroscope rotor khoom. Gyroscopes yog lub hlwb ntawm navigation thiab tswj systems ntawm aircraft, satellites, ntau yam missiles, spacecraft thiab nuclear submarines: lub stability ntawm gyroscopes nce nrog nce hnyav ntawm lub cev rotating. Txij li thaum gyroscope rotors tuaj yeem txhim kho koj txoj kev ruaj ntseg thiab tswj qhov tseeb.
2. Inertial rotating ntsiab ntawm aircraft.
3. Ntsuas cov khoom hnyav hauv ntau yam twj paj nruag thiab cav, xws li cov khoom hnyav uas siv hauv "Spey" cav thiab cov khoom hnyav uas tswj lub throttle thiab kho cov roj ntim ntawm kev kub ceev.
Tsis tas li ntawd, nws kuj tau siv dav rau qhov zoo li qub thiab muaj zog counterweights ntawm ob sab ntawm ailerons thiab rudders thiab counterweights rau rotating helicopter hniav.
Hauv kev ua tub rog, nws feem ntau yog siv hauv cov hauv qab no
1. High-density W-Ni-Fe alloy nrog qhov ceev heev, lub zog, plasticity thiab hardness yog ib qho tseem ceeb heev hauv kev lag luam tub rog. Nws yog siv los ua cov xub me me hauv cov mos txwv phom, hauv daim ntawv "hnab hmoov". foob pob hluav taws xob, foob pob hluav taws, foob pob hluav taws, foob pob hluav taws, foob pob foob pob thiab muaj kev tuag siab.
2. Nyob rau hauv missiles, nws yog siv raws li gyroscopic rotor ntawm missile seev, counterweight screws, hloov daim hlau thiab high-density alloy missile lub cev hnyav kaum kilograms.
3. Nyob rau hauv lub tank cav, nws yog siv los ua counterweight thaiv nyob rau hauv
