1 Khoom Description
C11000 tooj liab clad steel phaj tau dav siv vim nws muaj ob qho tib si tshwj xeeb ntawm cov khoom siv clad thiab lub zog thiab nruj ntawm cov khoom siv hauv paus. C11000 tooj liab clad steel phaj ua los ntawm kev sib txuas cov pa roj carbon steel raws li lub hauv paus txheej thiab tooj liab clad txheej yog tam sim no tau txais ntau thiab ntau xim. Cov phaj sib xyaw no muab kev ua si tag nrho rau qhov zoo ntawm ob cov ntaub ntawv, uas tsis yog tsuas yog muaj kev tiv thaiv corrosion, hnav tsis kam, siab conductivity, thiab thermal conductivity ntawm tooj liab, tab sis kuj muaj qhov zoo ntawm lub zog siab thiab qis tus nqi ntawm carbon steel, yog li ntawd. tooj liab / hlau puas phaj muaj kev thov zoo rau kev cia siab. Nws yog tsuas yog siv hauv kev lag luam tub rog, khoom siv hluav taws xob, khoom siv ua noj thiab kev kho vaj tse. Lwm yam kev lag luam suav nrog cov khoom siv hluav taws xob sib hloov, synchronizer nco nplhaib, reducer turbine, bearing bush, thiab lwm yam hauv kev lag luam tsheb, thiab electrodes hauv kev lag luam metallurgical.
2 Khoom nta
Tam sim no, tooj liab/steel composite daim hlau yog tsim los ntawm explosive bonding, explosive plus dov bonding, thiab diffusion bonding. Cov phaj sib xyaw siv hauv daim ntawv no yog tsim los ntawm kev tawg. Cov txheej txheem ntau lawm ntawm cov txheej txheem tawg yog raws li hauv qab no: ua ntej, muab cov phaj sib xyaw rau ntawm lub hauv paus phaj, thiab siv qhov sib txawv ntawm qhov nruab nrab kom tswj tau qhov kev ncua deb. Muab ib txheej ntawm cov khoom tawg thiab cov detonators tso rau ntawm daim phaj sib xyaw. Thaum cov khoom tawg yog detonated los ntawm detonators, cov explosives yuav kis mus rau pem hauv ntej ntawm lub composite phaj ntawm lub detonation ceev. Lub zog kinetic loj uas tsim los ntawm kev tawg nthwv dej thiab tawg nrawm nrawm yog xa mus rau lub phaj clad, uas ua rau lub phaj clad txav mus rau lub substrate ntawm kev kub ceev. Cov phaj clad thiab lub substrate sib tsoo ua tiav ntawm qhov chaw sib cuag, ua rau muaj zog yas deformation. Nyob rau hauv cov txheej txheem no, feem ntau ntawm cov kinetic zog yog hloov mus rau hauv lub tshav kub lub zog, thiab ib tug loj npaum li cas ntawm tshav kub lub zog melts cov hlau nyob rau hauv cov xwm txheej ntawm ze li ntawm adiabatic, thiab paub txog cov vuam ua ke nyob rau hauv qhov kev txiav txim ntawm kev kub siab. Daim duab 1 yog daim duab kos ntawm cov txheej txheem vuam tawg.
3Qhov cuam tshuam ntawm annealing ntawm microstructure
Lub phaj tooj liab / hlau sib xyaw yuav ua tiav peb theem sib txawv ntawm kev rov qab, recrystallization, thiab kev loj hlob ntawm cov nplej thaum lub sij hawm annealing, uas tuaj yeem siv los hloov cov qauv ntawm cov hlau kom tau txais cov khoom txhim khu kev qha. Kev kho cua sov sib txawv yuav cuam tshuam rau microstructure ntawm tooj liab / hlau sib xyaw phaj, tab sis microstructure ntawm Q235B thiab microstructure ntawm tooj liab ntawm qhov kub qis dua 700 degree muaj kev hloov me ntsis, qhia tias kev rov qab los ntawm qhov kub thiab txias. Daim duab 7 qhia txog microstructure ntawm tooj liab thaum annealed ntawm 750 thiab 800 degree. Nws tuaj yeem pom tau tias cov qauv tsim recrystallized tag nrho yog tsim ntawm 750 degree. Nws tuaj yeem txiav txim siab tias cov nplej tshiab tsis hloov pauv yuav rov tsim dua tshiab hauv cov deformed matrix saum 750 degree, thiab cov nplej loj hlob yuav tshwm sim nrog qhov kub thiab txias. Yog li, nws tuaj yeem txiav txim siab tias qhov kub ntawm qhov kub ntawm li 700 degree yog qhov kub thiab txias rau kev rov qab thiab recrystallization ntawm tooj liab / hlau puas phaj.
4 SEM thiab EDS tsom xam
Vim lub diffusion ntawm cov ntsiab lus thaum lub sij hawm tawg welding thiab lub tshav kub preservation nyhuv ntawm annealing kev kho mob, lub diffusion yuav tshwm sim nyob rau hauv lub bonding interface, feem ntau yog diffusion ntawm Fe thiab Cu. Ntawm qhov tod tes, lub ntsiab diffusion yog qhov tsim nyog rau kev txhim kho ntawm kev sib raug zoo ntawm lub zog; Ntawm qhov tod tes, cov khoom siv hlau yuav raug tsim los txo cov kev sib txuas ntawm lub zog. Daim duab 8 qhia txog qhov diffusion ntawm Cu thiab Fe cov ntsiab lus ntawm kev sib txuas ntawm tooj liab / hlau sib txuas phaj thiab lub thickness ntawm lub interface diffusion txheej nyob rau hauv txawv annealing kub. Nws tuaj yeem pom tau tias nrog qhov nce ntawm qhov kub thiab txias, lub thickness ntawm cov hlau alloy diffusion txheej yuav dav dua. Txawm li cas los xij, tsis muaj qhov sib xyaw ua ke thiab cov txheej tuab tsis hloov pauv ntau nyob rau hauv kev kho cua sov, 650 degree thiab 700 degree (qhov nkhaus tsis muab rau ntawm ob qhov ntsuas kub txwv rau qhov ntev), uas yog 1.5, 1.8. 2,0m ,ua. 700 degree annealing yog tsim nyog. Thaum qhov kub siab tshaj 750 degree, lub thickness ntawm diffusion txheej pom tseeb dav thiab cov kauj ruam tshwm sim, qhia tias cov tebchaw yog tsim nyob rau hauv lub interface, thiab diffusion txheej thickens sharply ntawm 800 degree, thiab cov melting txheej kuj thickens. Qhov kev txiav txim siab saum toj no kuj tuaj yeem kos los ntawm kev sib piv cov thickness ntawm cov txheej melting ntawm yoj crest hauv daim duab 9.
