Titanium clad steel phajintegrates zoo heev corrosion kuj ntawm titanium alloys thiab lub zog thiab toughness ntawm hlau thiab tau dav siv nyob rau hauv roj av, tshuaj, hluav taws xob, thiab nuclear zog teb. Nyob rau hauv xyoo tas los no, daim ntawv thov teb ntawm titanium-steel composite daim hlau yog maj mam nthuav dav, xws li cov ntaub ntawv tiv thaiv rau marine steel qauv, kev hloov cov pob qij txha ntawm lub nkoj steel qauv thiab cov qauv titanium, seawater pipelines, thiab lwm yam. Tib lub sij hawm, cov khoom siv technology ntawm titanium. titanium-steel composite daim hlau kuj ua tau zoo heev.
Tam sim no, txoj kev tsim khoom tseem ceeb ntawm titanium-steel clad phaj yog txoj kev tawg cladding, tawg-dov cladding txoj kev, thiab ncaj qha dov cladding txoj kev. Ntawm lawv, txoj kev ncaj nraim dov sib xyaw ua ke tau dhau los ua cov kev tshawb fawb tseem ceeb ntawm cov hlau zeb, uas yog vim yog kev taw qhia ntawm qhov loj-scale dov mills thiab lub tshuab nqus tsev vacuum. Piv nrog rau txoj kev tawg cladding thiab txoj kev tawg-dov cladding, txoj kev ncaj nraim rolling cladding txoj kev tuaj yeem tsim clad daim hlau nrog cov ntawv dav dav, nyias cladding, thiab cov khoom sib xws. Nyob rau tib lub sijhawm, txoj kev ncaj nraim dov sib xyaw kuj muaj qhov zoo ntawm kev tsim khoom siab thiab tus nqi qis. Txawm li cas los xij, lub tshuab nqus tsev tsim cov txheej txheem ntawm txoj kev ncaj nraim dov sib xyaw yog qhov nyuaj, thiab cov txheej txheem dov yuav tsum muaj cov cuab yeej siv siab. Rau cov tuam txhab hlau thiab hlau hauv tsev, tseem muaj qee cov thev naus laus zis tseem ceeb uas yuav tsum tau tawg los ntawm cov txheej txheem tsim khoom ntawm kev ncaj qha dov clad titanium steel clad daim hlau.
Qhov tseem ceeb ntawm cov txheej txheem dov ntawm titanium steel clad phaj yog cua sov, txo, thiab dov ceev, thiab cov cua kub kub yog cov txheej txheem tseem ceeb tshaj plaws. Qhov no yog vim qhov kub thiab txias tsis tsuas yog cuam tshuam rau cov txheej txheem txheej txheem ntawm titanium txheej thiab cov hlau txheej tab sis kuj cuam tshuam rau microstructure, lub zog, thiab tawv ntawm cov txheej steel, thiab kev sib txuas ua haujlwm. Qhov kub thiab txias cuam tshuam ncaj qha rau kev tsim cov theem ntawm interfacial brittle xws li TiC, FeTi, thiab Fe2Ti, thiab cov thickness ntawm interfacial brittle theem muaj kev txiav txim siab ntawm cov khoom sib txuas.
Cov txiaj ntsig tau pom tias lub zog ntawm lub ntsej muag shear yog inversely proportional rau lub thickness ntawm intermetallic txheej. Raws li qhov kub thiab txias, lub thickness ntawm intermetallic compound ntawm titanium-stainless hlau clad phaj nce. Thaum cov cua kub kub yog 850 degree, thermal simulation composite titanium stainless hlau qauv tau txais kev sib txuas zoo tshaj plaws. Txawm li cas los xij, cov txiaj ntsig kev tshawb fawb tam sim no feem ntau yog ua raws li kev sim phenomena, uas muaj feem xyuam rau kev sib raug zoo ntawm qhov kub thiab txias, interface khoom hom, thickness, thiab interface bonding kev ua tau zoo, thiab tsis sib sib zog nqus ntsuas qhov kub li cas cuam tshuam rau lub interface tshuaj tiv thaiv cov khoom hom thiab thickness. Yog li ntawd, qhov cuam tshuam ntawm qhov kub thiab txias ntawm qhov cuam tshuam interfacial theem yuav tsum tau kawm ntxiv. Tsis tas li ntawd, kuj tseem muaj qhov tsis muaj qhov ntsuas qhov ntsuas ntawm qhov cuam tshuam ntawm cov cua sov ntawm lub microstructure, lub zog thiab lub zog ntawm lub substrate, thiab lub zog sib txuas ntawm lub ntsej muag.
1) Thaum tshav kub kub yog 850 ~ 950 degree, lub zog thiab toughness ntawm lub hauv paus khoom, lub interface shear kev ua tau zoo, thiab cov txheej txheem dabtsi yog khoov kev ua tau zoo ntawm titanium hlau puas phaj tag nrho raws li qhov yuav tsum tau ntawm qhov Performance index, thiab shear zog yog siab tshaj 200MPa. Nrog rau qhov nce hauv qhov kub thiab txias, qhov kev ua haujlwm ntawm lub ntsej muag sib txuas tau qis zuj zus.
2) Thaum cov cua kub kub yog 850, 875 thiab 900 degree, qhov txias txias tom qab dov qis, lub peev xwm ntawm C ntawm kev sib txuas yog muaj zog, cov tshuaj tiv thaiv-diffusion ntawm Fe hauv Ti tsis muaj zog, thiab cov tshuaj tiv thaiv theem ntawm TiC thiab -Ti yog tsim los ntawm kev sib txuas lus.
3) Nrog rau qhov nce ntawm cov cua sov, lub thickness ntawm lub nkig theem TiC txheej thiab Fe-Ti intermetallic compound txheej nce. Thaum cov cua kub kub nce siab tshaj 925 degree, Fe-Ti intermetallic tebchaw thiab TiC coexist nyob rau hauv kev sib txuas lus. Kev sib txawv ntawm cov theem nkig thiab qhov nce ntawm cov tuab ua rau qhov sib cuam tshuam shear lub zog ntawm titanium-steel clad phaj txo.
