Dab tsi yog daim ntawv thov ntawm TB8 siab kub titanium alloy?

Kev tshawb fawb thiab kev loj hlob ntawm TB8 siab kub titanium alloy txheem qhov chaw yog tsuas yog tsom rau kub kub titanium alloys ntawm 600 degree. Cov txheej txheem hauv tsev ntawm titanium alloys yog tsim los ntawm lub koom haum ntawm Metallurgy ntawm Suav Academy ntawm Sciences.Cov khoom xyaw ntawm Ti60 titanium alloy yog ze-alpha-type heat-strengthened titanium alloy txhim kho raws li Ti-5 .5Al-4Sn-2Zr-1Mo-0.3Si-1ND-0.05CTI55, thiab nws cov kev ua tau zoo tau raug txhim kho los ntawm ND ntxiv dag zog. Qhov kub ua haujlwm ntev ntawm cov hlau no tuaj yeem ncav cuag 600 degree, uas yog tsim rau compressor disks, nruas thiab hniav nyob rau hauv lub siab siab seem ntawm aircraft transmitters. Kev tshawb fawb hauv tsev ntawm lub zog muaj zog titanium alloys feem ntau yog tsom rau TB8TC21 thiab lwm hom ntawm titanium alloys (tsim los ntawm Northwest Nonferrous Institute) TB8 titanium alloy muaj cov ntsiab lus ntawm Ti-15Mo-3Al{{24 }}.7Nb-0.2Si nruab nrab-stabilized-type titanium alloy. TB8 titanium alloy tuaj yeem siv tau ntxiv rau kev noj cov ntawv thiab sawb, tab sis kuj tseem foils, filaments, hlab, rods thiab forgings. Lub phaj yog tsuas yog siv nyob rau hauv kev tsim khoom ntawm nruab nrab complexity ntawm aircraft txias forming sheet hlau qhov chaw, tuaj yeem hloov qhov siv theem ntawm 30CrMnSiA cov qauv hlau. Lub TC21 titanium alloy tshiab tsim muaj cov khoom siv ruaj khov thiab sib tw cov ntsuas lub zog, plasticity, tawg toughness, tawg txuas ntxiv tus nqi, thiab lwm yam. Nyob rau hauv cov nqe lus ntawm nplaim taws retardant titanium alloy, Northwest Nonferrous hlau lub koom haum tau tsim Ti40 nplaim retardant titanium alloy nrog Suav yam ntxwv ntawm tus nqi qis. Ti-V-Cr system Ti-25V-15Cr-0.2Si siab alloying muaj pes tsawg leeg ntawm Ti-V-Cr system ntawm tag nrho beta titanium alloy, nrog zoo tsis kam mus quenching kev ua tau zoo thiab kev ua haujlwm kub kub. ti40 titanium alloy yuav haum rau lub dav hlau launchers cov khoom tseem ceeb ntawm cov ntawv xov xwm thiab cov hniav.

Ntau pua hom tau koom nrog, thiab nws tau nkag siab tias cov txheej txheem siab hauv paus titanium fasteners tsim los ntawm Aerospace Precision, ib lub koom haum ntawm Aerospace Science thiab Kev Lag Luam, yog cov hlau txuas txuas cov khoom ntawm manned spaceflight engineering. Cov kws tshaj lij koom nrog hauv kev txhim kho tau ua tiav daws teeb meem ntawm cov teeb meem tseem ceeb xws li titanium alloy upsetting, pwm tsim, thiab lwm yam, uas muab cov neeg siv nrog kev ruaj ntseg.

Yog li ntawd, galvanic coupling corrosion thiab crevice corrosion tau dhau los ua kev puas tsuaj tseem ceeb rau cov qauv aviation. Standard crevice corrosion test, standard galvanic coupling corrosion test, electrochemical polarization test, neutral salt spray test thiab cyclic immersion corrosion test yog siv vim muaj ntau yam ntaub ntawv hauv cov qauv aviation nquag hu thiab siv. Daim ntawv no tham txog kev tiv thaiv corrosion ntawm aerospace titanium alloy fasteners thiab lawv cov qauv sib txuas hauv ib puag ncig marine simulated. Cov titanium raj tau soj ntsuam rau kev txhim kho corrosion los ntawm kev tshuaj ntsuam xyuas electron microscopy thiab x-ray diffraction, thiab kev sib cuag tiv thaiv corrosion schemes tau npaj.

Cov txiaj ntsig tau pom tias carbon fiber epoxy composites co-kho iav ntaub ntawm lub fastener ntsia hlau pob qij txha tuaj yeem tswj kev sib cuag corrosion ntawm carbon fiber epoxy composites thiab titanium fasteners, thiab kev sib txuas ua ke ntawm carbon fiber epoxy composites yog mem tes-anodized TC16 bolts nrog mem tes. -anodized TC16 txiv ntseej (MoS_2 du)

Los yog txuas pulse anodized thiab xiav anodized titanium bolts tsis hais txog qhov sib piv ntawm qhov sib txawv. Stainless hlau txiv ntseej Cr17Ni2 corrosion kuj yog tag nrho superior rau 1Cr11Ni2W2MoV Anodized LY12 txhuas alloy ceev muaj corrosion kuj zoo dua stainless hlau ceev. Hais txog cov khoom siv anodized aluminium LY12 interlayer, corrosion kuj ntawm cov qauv anodized nrog cladding txheej yog zoo dua li ntawm cov qauv anodized nrog de-cladding txheej, thiab fastener articulation txoj kev npaj yog raws li nram no: titanium alloy TC16 bolts nrog txhuas plating thiab passivation, ua ke nrog anodized LY12 txiv ntseej.
