Hauv thaj teb ntawm cov ntaub ntawv muaj cov ntaub ntawv ntshiab, cov phiaj av ntshiab thiab cov phiaj titanium nthuav tawm cov khoom siv uas sib txawv vim lawv cov qauv sib txawv. Cov kab lus no ntsuas cov khoom siv, kev ua kom cov yam ntxwv ua tau zoo, thiab cov kev siv tswv yim, muab cov kev xaiv scientific rau kev xaiv cov khoom lag luam.
I. Kev ua caj ces hauv cov khoom siv
Ntshiab titanium phaj, ib tug sawv cev ntoo khoom siv, yog raws li ib tug -type crystal qauv thiab feem ntau ua tiav txoj kev coj dawb tshaj 99%. Nws cov kev tsim khoom nyob ntawm lub tshuab nqus tsev muaj cov tshuab arc melting (var) thev naus laus zis, ua rau muaj kev zam ntau zaus. Cov cuab yeej hlau no uas cuam tshuam homogene zoo li qub. Tshwj xeeb, nyob rau hauv Aerospace teb, Ta1eli-qib hluav taws xob ntshiab tshaj lossis sib npaug rau 0.07%) tau dhau los ua cov khoom tseem ceeb rau Boeing 787 Fuselage daim tawv.
Kev sib xyaw cov titanium phaj siv nyob rau hauv lub caij nyoog tshiab ntawm fawm kib cladding. Los ntawm cov pob zeb tawg lossis kub dov cov txheej txheem cladding, ib qho 0.5-5 hli titanium txheej yog mus tas li steel hlau lossis stainless hlau substrate. Kev hloov txheej txheej siv ag72CU28 brazing muab tub lim hlau kom ua tiav kev sib tw metallurgical, ua tiav lub zog shear, ua tiav lub zog ntawm 140%. Cov qauv txheej txheem tshiab no tso cai rau cov khoom siv los ua ke cov khoom lag luam corrosion ntawm cov khoom siv hauv PTA nrog cov tshuaj reactors ntau tshaj 5 meters hauv lub cheeb.
Ii. Kev Ua Haujlwm Parameter Kev Sib Tw
Hais txog kev yoog raws li ib puag ncig heev, ntshiab titanium daim phiaj khav theeb ib qho kub tiv thaiv ntau yam ntawm -196℃rau 600 degree. Lawv lub zog tshwj xeeb ncav cuag 3.8-4.5, deb tshaj li cov neeg siv hlau loj heev, ua rau lawv tsis tseem ceeb hauv cov kua dej nitrogen cia. Hais txog biocompatibility, lawv cov duab oxide oxide ua raws ISO 5832-2, ua rau lawv cov khoom nyiam rau kev cog hniav sib koom tes.
Composite titanium daim phiaj yog ua pov thawj tshwj xeeb hauv kev ua kom muaj kev ua haujlwm-resistant ib puag ncig. Titanium tiv thaiv kev tiv thaiv kev tiv thaiv dej hiav txwv corrosion (corrosion tus nqi tsawg dua lossis sib npaug ntawm 0.001 hli / a), thaum lub hauv paus cov txheej txheem muab kev txhawb nqa. Cov nyhuv synergistic no nce qhov kev pabcuam lub neej ntawm cov cuab yeej tshuaj lom los ntawm ntau dua peb zaug. Hais txog kev lag luam, nws tuaj yeem txuag 40-70% ntawm titanium cov ntaub ntawv piv rau txhua hom-titanium qauv, muab cov nqi tseem ceeb nyob rau hauv lub loj-teev cia khoom siv.
III. Faib thiab sib koom ua ke nrog cov xwm txheej
Ntshiab titanium daim phiaj feem ntau yog siv nyob rau hauv aerospace thiab kev kho mob. Boeing 787 Fuselage cov tawv nqaij txo qhov hnyav los ntawm 20kg ib square meter, thiab lub sij hawm ntev ntawm pacemaker Casings ua rau lawv tus nqi tsis muaj nqis. Hauv kev lag luam tshuaj, ntshiab titanium daim phiaj, vim lawv qhov ruaj khov nyob rau hauv cov xov xwm hydrochloric acid thiab acetic acid, tau dhau los ua cov ntaub ntawv liner rau cov tshuaj lom neeg tshwj xeeb.
Puas yog cov phiaj phiaj titanium ua tus tsim kev tsim cov txheej txheem kev lag luam kev lag luam. Nyob rau hauv lub tswv yim siab sector, lawv lub siab ua haujlwm siab (ntau dua los yog sib npaug rau cov khoom siv oxidation rau cov nroj tsuag PTA. Hauv marine engineering, 3m-dav daim phiaj yuav tsim tau rau hauv dej hiav txwv muaj tej yam xwm txheej tsis kam thiab dej hiav txwv corrosion. IV. Ob lub helix ntawm kev hloov thev naus laus zis
Cov khoom siv thev naus laus zis yog tsav ob qho technologies rau qhov siab tshiab. Nyob rau hauv cov ntshiab titanium phaj sector, tsim ntau lawm ntawm dav titanium strips tshaj 2000mm tau ua tiav, thiab tshuab hluav taws xob txias tau txo cov qib kab mob PPM. Nyob rau hauv cov phaj technology, tshiab gradient Comprosite cov txheej txheem tau tawm, siv cov txheej txheem Nanostructures txheej los nce interfacial lub zog los ntawm 30%. Online Seeb Soj Ntsuam Lub Nruab Nrab Sib Koom Tes Ultrasonic C-Scan Technology rau 100% tsis yog kev ua phem rau kev sib cuam tshuam ntawm kev sib cuam tshuam.
Kev xaiv engineavering yuav tsum ua raws li ASTM B265 thiab ASME SB898 tus qauv kev cai txheeb xyuas (LCCA) rau kev txiav txim siab. Cov ntaub ntawv tam sim no qhia tau hais tias cov phiaj titosite muaj cov phiaj xwm 35% ntshiab hauv cov lus txib 95% kev sib koom ua lag luam hauv phau ntawv biomedical. Kev txhim kho kev txhim kho no yuav txuas ntxiv mus rau kev siv cov ntaub ntawv infanium ntawm titanium cov ntaub ntawv hauv kev tsim khoom siab.
Lub tuam txhab khav ua cov khoom lag luam hauv tsev titanium ua ntau lawm, nrog rau:
German-imported precision titanium raj ntau lawm kab (txhua xyoo muaj peev xwm ntau lawm: 30,000 tons);
Japanese-technology technology tentanium ntawv ci rolling kab (thinnest rau 6μm);
Qoos motated titanium qws txuas ntxiv mus rau kab extrusion;
Ntse titanium phaj thiab sawb fining;
MES system ua noj digital tswj thiab kev tswj hwm ntawm tag nrho cov txheej txheem ntau lawm, ua tiav cov khoom lag luam seem ntawm ± 0.01M.
