Aluminium qhov chaw
Aluminium alloy yog alloy uas aluminium (AL) yog cov hlau tseem ceeb.
Cov ntsiab lus tseem ceeb yog tooj liab, magnesium, manganess, silicon thiab zinc.
Muaj ob qhov kev faib tawm tseem ceeb, uas yog cov hlau nplaum thiab cov hlau tsis sib haum, ob qho tib si tau muab faib ntxiv rau hauv cov khoom siv hluav taws xob kho tau thiab tsis muaj cua sov kho.
Aluminium alloy muaj ntau heev nyob rau hauv peb lub neej, peb lub qhov rooj thiab qhov rais, txaj, ua noj ua haus tais diav, tais diav, tsheb kauj vab, tsheb thiab lwm yam. Muaj aluminium alloy.
Ordinary aluminium alloy nyob rau hauv daim ntawv thov ntawm lub neej.
Aluminium alloys nrog ntau yam ntawm cov khoom yog qhia txog engineering hauv structures.
Kev xaiv cov hlau zoo rau daim ntawv thov suav nrog kev txiav txim siab ntawm nws lub zog tensile, ntom, ductility, formability, workability, weldability thiab corrosion los tuav.
Aluminium alloy yog siv dav hauv cov dav hlau vim qhov siab zog rau qhov hnyav piv.
Aluminium alloys feem ntau muaj qhov elastic modulus txog 70GPa, uas yog kwv yees li ib feem peb ntawm elastic modulus ntawm feem ntau ntawm cov hlau thiab hlau alloys.
Yog li ntawd, rau ib tug muab load, ib tug tivthaiv los yog chav tsev ua los ntawm ib tug txhuas alloy yuav kim dua elastic deformation ntau dua li ib feem ntawm cov hlau zoo tib yam ntawm cov duab.
Lub teeb zoo, siab zog, corrosion, tsis kam, yooj yim sib sau, vuam.
Alloys muaj feem ntau ntawm txhuas tau tseem ceeb heev nyob rau hauv aerospace manufacturing txij thaum pib ntawm cov hlau skinned aircraft.Aluminium magnesium alloys yog ob qho tib si sib dua li lwm cov aluminium alloys thiab ntau tsawg flammable dua alloy uas muaj feem pua ntawm magnesium.
Feem ntau, cov hlau rhiab heev rau cov cua sov kuj tseem raug txiav txim siab, txawm tias cov txheej txheem ua haujlwm niaj hnub uas muaj cua sov yog qhov nyuaj los ntawm qhov tseeb tias txhuas, tsis zoo li cov hlau, yuav yaj yam tsis muaj thawj ci liab.
Aluminium alloy nto yuav ua kom lawv pom meej ci nyob rau hauv ib puag ncig qhuav vim yog tsim kom pom tseeb, tiv thaiv txheej ntawm aluminium oxide.Nyob rau hauv ib qho chaw ntub dej, galvanic corrosion tuaj yeem tshwm sim thaum aluminium alloy muab tso rau hauv hluav taws xob tiv tauj nrog lwm cov hlau uas muaj qhov tsis zoo corrosion ntau dua li txhuas.
Lub ntsiab alloying ntsiab yog tooj liab, silicon, magnesium, zinc, manganese, lwm yam alloying ntsiab yog nickle, hlau, titanium, chromium, lithium, thiab lwm yam.
Aluminium alloy yog siv dav hauv kev lag luam ntawm cov khoom siv hlau tsis muaj hlau nyob hauv aviation, aerospace, automotive, machinery manufacturing, shipping thiab tau siv dav hauv kev lag luam tshuaj.
Aluminium alloy ceev yog tsawg, tab sis qhov kev siv yog siab.
Cov alloys uas siv rau tuag casting yog tam sim no ua los ntawm txhuas alloy.Nws muaj lub cev lub zog ntawm lub teeb thiab zoo corrosion kuj thiab txhua yam khoom, thiab zoo thermal conduction.Aluminium alloy tuaj yeem muab faib ua cov khoom siv thiab casting, thiab tuaj yeem muab faib ua ob hom: kub-kho aluminium alloy thiab tsis kub kho aluminium alloy cov ntaub ntawv hauv cov ntaub ntawv ua.Tuag casting aluminium alloy yog cov khoom siv casting, thiab aluminium alloy uas siv feem ntau tsis haum rau kev kho cua sov vim nws tau ua tiav rau hauv cov khoom los ntawm kev tuag casting.
Aluminium silicon series
General aluminium alloy, xws li ADC1, siv rau cov phab ntsa loj, nyias thiab cov duab nyuaj.Cov ntsiab lus ntawm silicon ntsiab nyob ze eutectic taw tes thiab ua rau lub casting molten liquidity yog zoo, nws muaj zoo castability, corrosion kuj, siab thermal conductivity, thermal expansion thiab qhov feem ntawm tsawg 2.65g / cm3, thiab lwm yam.Txawm li cas los xij, nws tsis zoo rau nkig thiab nkig, thiab anodic oxidation tsis zoo.Yog hais tias cov txheej txheem casting tsis haum, cov kua molten qeeb.
Aluminium silicon tooj liab
ADC12 alloy yog nyob rau hauv Al-Si alloy ntxiv tooj liab alloy caij, yog cov feem ntau dav siv cov sawv cev ntawm cov tuag casting txhuas alloy, nws zoo heev castability thiab txhua yam khoom, tab sis tsis zoo corrosion kuj.
Aluminium-Silicon-Magnesium series
ADC3 aluminium alloy yog nyob rau hauv Al-Si alloy ntxiv cov hlau alloy xws li Mg, Fe, nrog cov khoom siv zoo heev, corrosion kuj zoo castability, tab sis thaum cov ntsiab lus ntawm cov hlau tsawg dua 1% yooj yim adhesion nrog cov hlau pwm, alloy yog dav siv.Lwm qhov ADC5 thiab ADC 6 alloys, tseem hu ua aluminium-magnesium alloys, muaj zog dua, corrision resistant thiab machined, thiab yog qhov zoo tshaj plaws hauv aluminium alloy.Txawm li cas los xij, vim qhov loj ntawm solidification thiab thermal expansion coefficient, cov hlau casting tsis zoo.Ib qho dej tsis zoo kuj tsis zoo, ua rau muaj qhov tshwm sim tsis zoo thiab poob ntawm cov hlau nplaum tom qab sib tsoo, yog li nws tsim nyog rau kev kho anodic oxidation, thiab lwm yam impurity xws li hlau, silicon thiab lwm yam cuam tshuam rau lub ntsej muag.
Ntau lub teb chaws muaj cov npe sib txawv rau cov txhuas txhuas tuag, xws li Axxx yog tus qauv Asmeskas, ADCxx yog tus qauv Japanese, LMxx yog tus qauv Askiv, YLxxx yog Suav qauv.
Kev kho deg ntawm tuag casting aluminium alloy qhov chaw
Cov anodic oxidation.
Nyob rau tib lub sijhawm, nws muaj qhov ua haujlwm zoo thiab zoo nkauj, thiab feem ntau anodized aluminium alloy yog li 2-25um.
High durability thiab anti-coj aluminium alloy castings muaj 25-75um nto thickness.Aluminium alloy oxide txheej tuaj yeem ua tiav thiab tsim.
Txhua yam xim tsis muaj hluav taws xob thaum nws raug oxidized, yog li lawv tuaj yeem siv nyab xeeb hauv ntau qhov chaw ntawm cov khoom siv hluav taws xob.
Phosphide / chromium.
Phosphatification yog ib qho tseem ceeb uas tsis yog hlau thiab nyias txheej uas tsim cov txheej txheem hloov ntawm cov hlau los ntawm cov phosphorus tebchaw.
Nws siv rau steel, zinc alloy, aluminium alloy thiab lwm yam khoom, uas tuaj yeem txhim kho corrosion kuj thiab hnav tsis kam.
Lub daim nyias nyias yog tam sim no qhov zoo tshaj plaws resistant rau txhuas hloov dua siab tshiab zaj duab xis, yog li nws muaj peev xwm yuav kho raws li ib tug txheej txheej ntawm aluminium alloy.
Micro-arc oxidation.
Siv high voltage ntawm txhuas qhov chaw los ua ceramic nto zaj duab xis, txheej hardness thiab abrasion kuj yog siab heev, thiab corrosion kuj thiab tshwj xeeb.
Cov npoo yog zoo dua li cov anode.
Lub microarc membrane yog tsim los ntawm peb pawg:
Thawj txheej yog nyias zaj duab xis txuas rau saum npoo ntawm txhuas, uas yog li ntawm 3 mus rau 5um.
Qhov thib ob txheej yog qhov tseem ceeb ntawm daim nyias nyias, uas yog li ntawm 150 txog 250um.Lub ntsiab txheej yog siab hardness thiab porosity yog me me thiab denser yog siab heev.
Qhov thib peb txheej yog txheej txheej kawg.Cov txheej no yog xoob thiab ntxhib, yog li nws feem ntau yuav ua tiav thiab tshem tawm siv ntawm lub ntsiab txheej.
Lub alunina microarc oxidation yog piv nrog anodic oxidation.
Kev siv ntawm microarc oxidation technology:
Aviation accessories: pneumatic Cheebtsam thiab sealing qhov chaw.
Auto qhov chaw: piston nozzle
Cov khoom siv hauv tsev: faucet, hluav taws xob hlau.
Cov cuab yeej hluav taws xob: ntsuas thiab hluav taws xob rwb thaiv tsev.
