Thaum tsim cov iav ib leeg lossis cov txheej txheem iav, kev xaiv cov khoom siv yog lub hauv paus tseem ceeb uas txiav txim siab qhov geometry ntawm lub iav, lossis kev ua tau zoo ntawm lub iav txiav txim siab xaiv cov khoom siv raug rau lub iav. Muaj ntau ntau yam khoom siv raw siv hauv kev tsim iav, thiab txhua cov khoom siv raw muaj qhov kev xaiv zoo, thiab nws cov khoom siv tshuab yog qhov zoo tagnrho. Cov ntaub ntawv tseem ceeb ntawm cov khoom yog tooj liab tooj liab, hlau hlau thiab txhuas txhuas.
Los ntawm kev sib xyaw ua kom raug thiab ua tiav, aluminium alloy zog tuaj yeem tau txais ntau yam zoo. Cov khoom siv txhuas txhuas feem ntau yog siv los tsim lub sijhawm siv log, racks thiab lwm yam khoom siv qis. Kev ua haujlwm thev naus laus zis ntawm aluminium alloy zog yog tib yam li ntawm cov hlau alloy zog (xws li milling, iav hobbing, iav shaping, thiab lwm yam).
Aluminium alloy tuaj yeem hais tau tias yog ib qho ntawm peb cov hlau feem ntau. Lub cev nyhav thiab lub zog siab ntawm aluminium alloy ua rau nws yog qhov kev xaiv zoo tshaj plaws rau ntau daim ntawv thov. Tom qab cov hlau, aluminium alloys tau qhuas rau lawv qhov kev txhim kho corrosion thiab lub cev hnyav. Cov yam ntxwv ntawm txhuas ua rau nws tshwj xeeb tsim rau ntau yam kev siv hluav taws xob thiab hluav taws xob, xws li cov khoom siv hluav taws xob muaj zog, cov iav ua haujlwm, cov kav hlau txais xov parabolic, lub tshuab computer, thiab lwm yam.
Dab tsi yog cov yam ntxwv ntawm aluminium alloy zog
Aluminium alloy yog lwm txoj hauv kev zoo dua rau cov hlau hlau thiab tsim nyog rau daim ntawv thov nrog lub zog siab rau qhov hnyav piv. Qhov hnyav ntawm aluminium alloy yog ib feem peb hnyav dua li cov hlau hlau ntawm tib qhov loj. Aluminium alloy zog muaj cov yam ntxwv ntawm corrosion kuj thiab lub cev hnyav. Qhov saum npoo tuaj yeem tiv thaiv lub zog txhuas hlau los ntawm oxidation thiab corrosion. Qhov no zoo ib yam li xeb ntawm cov hlau hlau, nws yuav npog saum npoo thiab tiv thaiv nws los ntawm kev puas tsuaj ntxiv. Aluminium alloy yog kim dua li cov pa roj carbon, tab sis pheej yig dua li cov hlau tsis huv. Txawm li cas los xij, lawv yooj yim rau txheej txheem, uas txo qhov nce ntawm cov nqi khoom.
Txhuas iav
Aluminium tau ua pov thawj tias muaj ntau yam zoo hauv keeb kwm, thiab nws tseem niaj hnub no. Kev lag luam aerospace txuas ntxiv tau txais txiaj ntsig los ntawm cov yam ntxwv ntawm cov khoom siv los tsim kev nyab xeeb, txhim khu kev qha thiab pheej yig dua cov khoom siv tshuab. Aluminium alloy khoom pib hloov pauv ntawm 400 ° F, yog li nws tsis tuaj yeem siv rau hauv qhov kub thiab txias ib puag ncig. Muaj ntau hom sib txawv ntawm cov khoom siv txhuas txhuas, thiab feem ntau siv cov khoom siv txhuas txhuas rau kev ua cov txheej txheem aluminium alloy yog 2024, 6061 thiab 7075.
Ntawm cov ntaub ntawv no, 2024 txhuas hlau tuaj yeem hais tau tias yog tus txheeb ze ze ntawm txhuas tooj liab, thiab nws tseem yog hlau txhuas thiab tooj liab. Lub ntsiab alloying tseem ceeb hauv 2024 txhuas hlau yog tooj liab. Thaum xav tau lub zog siab-rau-hnyav piv, 2024 txhuas tuaj yeem siv tau. Txawm li cas los xij, hauv qhov no, qhov sib piv tau thim rov qab. Cov tooj liab hauv xyoo 2024 muab cov hlau no ua kom muaj zog, tab sis txo qis nws qhov kev txhim kho corrosion. 7075 txhuas sib xyaw ua ke zinc thiab magnesium nrog txhuas los ua lub zog muaj zog uas tiv taus kev nyuab siab. 6061 txhuas hlau yog ib qho hlau ntawm txhuas, silicon thiab magnesium. Qhov no yog nruab nrab-lub zog aluminium alloy nrog kev txhim kho corrosion zoo thiab weldability. Peb lub aluminium alloy zog saum toj no tuaj yeem kho cua sov kom nce lawv cov tawv. Aluminium alloy zog suav nrog spur zog thiab helical zog.
Qhov zoo thiab qhov tsis zoo ntawm aluminium alloy zog
Aluminium alloy khoom hauv aluminium alloy zog yog suav tias yog cov khoom siv tau ruaj khov. Ib qho tseem ceeb yog tias nws tuaj yeem siv tau dua thaum tseem khaws nws cov yam ntxwv qub. Qhov no yog qhov txiaj ntsig zoo heev, tsis yog tsuas yog siv tus nqi, tab sis kuj zoo rau ib puag ncig. Ib qho ntxiv, aluminium alloy zog kuj muaj qhov zoo ntawm kev tiv thaiv corrosion. Thaum aluminium alloy raug nthuav tawm rau saum huab cua, txheej nyias ntawm aluminium oxide yuav tsim rau ntawm nws saum npoo. Cov txheej no tiv thaiv aluminium alloy los ntawm kev xeb thaum raug.
Aluminium alloy zog muaj lub zog tensile siab dua thiab hnyav dua, yog li txo qhov hnyav ntawm tag nrho cov qauv, yog li txo nqi roj. Thaum aluminium alloy raug nthuav tawm rau huab cua, txheej oxide zoo yuav tsim rau ntawm nws saum npoo, ua rau nws tiv taus xeb. Ib qho ntxiv, aluminium alloy zog kuj muaj qhov zoo ntawm lub zog siab. Lub zog ntawm aluminium alloy tso cai rau nws hloov cov hlau hnyav dua yam tsis tau poob lub zog cuam tshuam nrog lwm cov hlau, thaum tau txais txiaj ntsig los ntawm nws qhov hnyav dua.
Txhuas iav
Qhov tsis zoo ntawm aluminium alloy zog yog tias tag nrho lub zog ntawm aluminium alloy zog tsis zoo dua li ntawm cov hlau alloy zog: txawm hais tias tau qhuas rau nws cov yas, qhov tshwj xeeb tus yam ntxwv ntawm txhuas kuj tseem yuav muaj qhov tsis zoo. Piv nrog hlau, nws yooj yim dua rau txhuam thiab khawb. Hlau muaj zog thiab tsis zoo li yuav warp, deform lossis khoov hauv qab qhov hnyav, quab yuam lossis cua sov.
