Nws yog qhov dav ntawm titanium alloys nyob rau hauv kev lag luam tsim kev lag luam vim yog lawv cov kev sib txawv-qhov hnyav ua piv txwv, thiab zoo tshaj qhov txhawm rau txhawm rau txhawm rau txhawm rau kom xeb. Muaj ntau cov tuam txhab tshaj li nyiam siv titanium alloy tc11 hloov chaw tsim khoom thiab muaj peev xwm ua haujlwm tau zoo nyob rau hauv lub sijhawm ntev. Titanium alloys yog cov khoom siv nyuaj-rau-tshuab nyuaj kom muaj lub zog siab thiab qhov kub thiab txias txiav kom muaj kev kub ntau. Rau qee qhov chaw txua Aero, xws li impellers, uas muaj cov chaw sib tw, nws yog qhov nyuaj rau kev ua haujlwm siab dua thiab siab dua li siv milling kev ua haujlwm.
Hauv kev siv tsheb sib txuas sab hauv lub cav, ib lub turbocharger rotor tau pab txhawb nqa cov hluav taws xob ua haujlwm thiab cov roj txo qis yam tsis muaj kev siv roj ntxiv. Txawm li cas los xij, lub turbocharger rotor muaj cov neeg tuag tsis zoo hu ua '' turbo-lags '' uas qeeb lub xeev ruaj khov ntawm turbocharger nyob rau hauv 2000 rpm. Titanium cathides tuaj yeem txo qhov hnyav rau ib nrab ntawm cov turbocharger. Dhau li, tial alloys muaj kev sib xyaw ua ke tsawg, muaj lub zog muaj zog, thiab cua sov zoo. Raws li, tial alloys tuaj yeem tshem tawm cov teeb meem kev lag luam turbo-lag. Txog tam sim no, rau kev tsim khoom ntawm turbocharger, hmoov metallurgy thiab casting cov txheej txheem tau sib xyaw. Txawm li cas los xij, nws yog ib qho nyuaj rau thov hmoov metallurgy process rau turbocharger tsim, vim nws lub suab tsis zoo thiab weldability.
Los ntawm qhov kev pom ntawm cov txheej txheem them nqi them nqi, peev txheej txheem tuaj yeem suav tias yog kev lag luam netolic net-puab thev naus laus zis rau kev lag luam tial alloys. Txawm li cas los xij, lub turbocharger muaj ob qho tib si curvature thiab nyias cov ntaub ntawv me, thiab tsis muaj fastability thiab fwv nrog pwm thiab kub thiab txias thiab centrifugal quab yuam. Tus qauv ntawm CASTING muaj lub zog thiab tus nqi-ua tau los kawm cov txiaj ntsig ntawm kev ua haujlwm ntau.
