Hauv kev tsim hluav taws xob aerospace, kev xaiv cov khoom siv tsis yog qhov kev txiav txim siab thib ob - nws ncaj qha txhais cov kev txwv kev ua haujlwm, cov npoo kev nyab xeeb, thiab cov nqi ntawm lub neej. Ntawm cov kev qhia dav tshaj plaws siab - cov hlau ua tau zoo, titanium alloys thiab npib tsib xee-raws li superalloys xws li Inconel sawv tawm raws li ob txoj hauv kev sib txawv rau cov kev xav tau ua haujlwm hnyav. Kev xaiv ntawm lawv yuav tsum muaj kev nkag siab meej txog lawv tus cwj pwm kev siv tshuab, thermal muaj peev xwm, thiab kev tsim khoom.
Titanium, tshwj xeeb tshaj yog Ti-6Al-4V, tau dhau los ua cov khoom tseem ceeb rau cov qauv dav hlau niaj hnub no. Nws qhov txiaj ntsig txhais tau yog nyob rau hauv nws lub zog tshwj xeeb- rau qhov hnyav piv-xa lub zog tensile nyob ib ncig ntawm 900 MPa ntawm qhov ntom ntom ntawm kwv yees li 4.5 g / cm³. Qhov kev sib xyaw ua ke no tso cai rau cov neeg ua haujlwm kom txo qis qhov hnyav ntawm cov qauv yam tsis muaj kev cuam tshuam cov neeg kho tshuab kev ncaj ncees, yog ib qho tseem ceeb hauv kev txhim kho roj efficiency thiab lub peev xwm them. Yog li ntawd, titanium feem ntau siv rau hauv cov qauv airframe, tsaws iav brackets, thiab hydraulic system Cheebtsam, qhov twg siab zog thiab corrosion kuj yuav tsum tau nyob rau hauv nruab nrab kub tej yam kev mob.
Nyob rau hauv sib piv, Inconel alloys xws li 718 thiab 625 yog engineered rau ib puag ncig uas kub tsis kam ua qhov tseem ceeb yuav tsum tau. Cov npib tsib xee-raws li superalloys tuav lub zog txhua yam thiab oxidation tsis kam ntawm qhov kub nce mus txog 1000 degree, ua rau lawv tseem ceeb hauv kev siv dav hlau dav hlau. Turbine blades, combustion chambers, thiab cov tshuab tso pa cia siab rau Inconel lub peev xwm ua tau raws li kev kub ntxhov siab tsis muaj deformation lossis creep. Thaum hnyav dua li titanium, nws qhov ruaj khov nyob rau hauv huab cua ua rau nws hloov tsis tau hauv qhov kub siab - thaj tsam kub.
Los ntawm kev xav machining, ob qho tib si cov ntaub ntawv nthuav tawm cov teeb meem tseem ceeb, txawm tias yog vim li cas sib txawv. Titanium cov thermal conductivity tsawg ua rau kub siab rau ntawm qhov chaw txiav, ua rau muaj kev pheej hmoo ntawm cov cuab yeej hnav thiab ua haujlwm tawv. Qhov no yuav tsum muaj kev teeb tsa nruj, cov cuab yeej txiav ntse, thiab tswj kev txiav kom tswj tau qhov tseeb qhov tseeb. Inconel, ntawm qhov tod tes, yog qhov nyuaj thiab tiv taus ntau dua rau kev deformation, xav tau qeeb txiav nrawm thiab feem ntau siv cov khoom siv ceramic lossis coated carbide. Cov txheej txheem machining yog ntau lub sijhawm- hnyav, uas cuam tshuam ncaj qha rau cov nqi tsim khoom thiab lub sijhawm ua haujlwm.
Lub peev xwm kam rau siab yog lwm qhov kev xav tau rau cov tuam txhab aerospace. Nrog cov txheej txheem ua kom zoo, cov khoom siv titanium feem ntau tuaj yeem ua tiav qib siab ntawm ± 0.005 hli, ua rau lawv haum rau siab - qhov raug cov qauv. Inconel Cheebtsam, vim lawv cov machining complexity thiab cov khoom coj tus cwj pwm, feem ntau muaj nyob rau hauv ± 0.01 hli tolerances. Txawm hais tias tseem muaj tseeb, qhov sib txawv no tuaj yeem cuam tshuam rau kev xaiv cov khoom siv hauv cov rooj sib txoos uas qhov kev zam nruj yog qhov tseem ceeb.
Daim ntawv thov kev xav tau kawg txiav txim siab cov khoom tsim nyog. Rau cov khoom siv ua haujlwm hauv qab li ntawm 600 degree, qhov txo qhov hnyav thiab lub zog ntawm lub zog yog qhov tseem ceeb, titanium muab cov kev daws teeb meem zoo heev. Rau qhov chaw raug tshav kub heev, thermal cycling, thiab oxidative ib puag ncig, Inconel muab kev ntseeg siab tsis sib haum txawm tias muaj ntau dua qhov ntom ntom thiab cov nqi ua haujlwm.
Kev kho deg ntxiv txhim kho kev ua tau zoo ntawm ob qho khoom siv. Titanium Cheebtsam feem ntau yog anodized los txhim kho corrosion kuj thiab nto durability, thaum Inconel feem feem ntau undergo passivation los txhim kho oxidation tsis kam thiab nto stability nyob rau hauv ib tug nruj heev puag ncig. Cov ntawv tshaj tawm no - cov kauj ruam ua tiav yog qhov tseem ceeb hauv kev ua kom tau raws li kev lees paub ntawm aerospace thiab cov kev xav tau ntev.
Hauv kev ua haujlwm engineering, kev xaiv cov khoom siv tsis tshua muaj raws li ib qho kev ntsuas. Hloov chaw, nws suav nrog ntsuas qhov ntsuas qhov ntsuas kub, qhov xwm txheej thauj khoom, kev tsim khoom, thiab kev txwv tus nqi. Ntau lub tshuab aerospace suav nrog ob yam khoom siv tswv yim- siv titanium hauv thaj chaw ua haujlwm kom txo qhov hnyav, thiab Inconel nyob rau hauv cov cheeb tsam cua sov los xyuas kom muaj kev ruaj khov nyob rau hauv cov xwm txheej hnyav.
Rau aerospace engineers thiab cov tuam txhab tsim khoom, qhov kev txiav txim siab ntawm titanium thiab Inconel yog qhov kawg ntawm kev ua kom cov khoom ua tau zoo nrog lub hom phiaj xav tau. Ib qho zoo-cov ntaub ntawv xaiv tsis yog tsuas yog ua kom ua raws li cov qauv kev siv dav hlau nruj tab sis kuj tseem ua kom zoo tshaj qhov kev tsim khoom thiab kev ntseeg siab ntev ntev.
Raws li kev siv thev naus laus zis thev naus laus zis txuas ntxiv mus, lub peev xwm los ua lub tshuab thiab siv cov ntaub ntawv qib siab no tau dhau los ua qhov sib txawv tseem ceeb rau cov neeg siv khoom. Cov neeg tsim khoom muaj peev xwm xa cov kev ua siab ntev ntev, ruaj khov zoo, thiab cov txheej txheem muaj ntawv pov thawj yuav ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa cov tiam tom ntej ntawm siab -kev ua haujlwm aerospace.
