Titanium cladding khoom annealing nta
Nta ntawm titanium cladding khoom annealing:
Piv nrog rau kev kho cua sov ntawm lwm cov ntaub ntawv hlau, kev kho cua sov ntawm cov hlau clad daim hlau muaj ntau yam zoo sib xws. Piv txwv li, lawv yog rhuab mus rau ib tug predetermined kub ntawm ib tug tej yam ceev, khaws cia ntawm no kub rau ib lub sij hawm, thiab ces txias ntawm ib tug tej yam ceev. Tag nrho cov txheej txheem yog nqa tawm hauv huab cua lossis lwm yam xov xwm.
Piv nrog rau kev kho cua sov ntawm lwm cov ntaub ntawv, kev kho cua sov ntawm ib qho khoom siv cladding kuj muaj nws cov yam ntxwv tshwj xeeb. Ntawd yog, lub melting point thiab recrystallization kub, lub zog, plasticity, hnav tsis kam thiab corrosion kuj, tshwj xeeb tshav kub thiab thermal expansion coefficient, thiab lwm yam lub cev thiab cov ntshav ua kom muaj zog ntawm ntau tus tswv cuab uas tsim cov composite yuav tsum tau txiav txim siab, tshwj xeeb tshaj yog thaum. Lawv raug kub hnyiab tau txhawm rau txhawm rau tsim cov txheej txheem tsis zoo ntawm kev kho cua sov thiab kwv yees qhov cuam tshuam ntawm kev kho cua sov ntawm lawv cov qauv kev sib raug zoo, kev sib koom ua ke lub zog thiab lawv cov qauv matrix thiab cov khoom.
Cov txheej txheem ntawm titanium steel composite phaj muaj cov qauv hlau nyuaj heev. Raws li cov txheej txheem tsim khoom tshwj xeeb thiab kev kho cua sov, cov txheej txheem sib txuas yuav tsim cov theem nkig xws li TiC, FeTi, uas yuav cuam tshuam ncaj qha rau kev sib txuas ntawm lub zog thiab plasticity ntawm cov phaj sib xyaw. Lub hom phiaj ntawm kev sib xyaw phaj annealing yog txhawm rau tshem tawm cov kev ntxhov siab sab hauv, tsim rov qab thiab recrystallization hauv cov txheej txheem ua tiav, thiab tseem ua kom ruaj khov thiab homogenize cov qauv, tshem tawm cov theem teeb meem thiab txhim kho cov khoom siv kho tshuab.
Cov txheej txheem annealing ntawm explosive cladding cov ntaub ntawv yog tsim raws li cov hom phiaj sib txawv. Lub hauv paus ntsiab lus yog hais tias cov khoom uas muaj qhov qis tshaj melting point nyob rau hauv cov hlau yog txiav txim nyob rau hauv ib tug txwv txoj kev, thiab ces lub ntsiab ntsiab constituting cov hlau yog suav hais tias yog cov khoom tov los yog intermetallic tebchaw nyob rau hauv lub theem daim duab, los yog ob qho tib si. Nws tseem yog ib qho tseem ceeb uas yuav tau txiav txim siab seb cov khoom puas tau hloov mus rau theem ntawm qhov kub thiab txias, tshwj xeeb tshaj yog thaum kub kub annealing.
Cov txheej txheem annealing ntawm cov khoom siv no yog txiav txim siab los ntawm kev sim. Kev xaiv ntawm nws cov cua kub kub tuaj yeem ua raws li cov hauv qab no: qhov qis qis yog 1/3 ~ 2/5 ntawm qhov qis melting point ntawm cov hlau muaj pes tsawg leeg, thiab lub siab txwv yog 2/3 ~ 4/5 ntawm tib lub melting point. Rau cov hlau sib txuas uas tsis tsim cov sib txuas sib txuas ntawm cov khoom sib txuas, cov hlau tsis huv, thiab lwm yam, lawv cov cua kub cua sov yog qhov dav heev, tshwj xeeb tshaj yog qhov ntsuas kub siab tuaj yeem siab heev. Feem ntau, qhov kev txwv qis ntawm cov cua sov saum toj no yuav yog qhov kub thiab txias rau kev ntxhov siab.
Rau cov kev sib txuas ua ke uas tuaj yeem tsim cov sib txuas sib txuas ntawm qhov sib txuas ntawm qhov kub thiab txias thiab ib qho ntawm cov khoom muaj kev hloov pauv, piv txwv li, titanium cladding steel phaj, ntau qhov kev ntsuam xyuas tau ua pov thawj tias nws qhov kub thiab txias yuav tsum tsis txhob siab dhau, txwv tsis pub. kev sib xyaw ua ke poob yuav loj dhau thiab qis dua tus qauv kev. Nyob rau lub sijhawm no, nws yog qhov tsis sib xws los xyuas kom muaj kev sib raug zoo txaus.

1. qhov kub thiab txias ntawm 500 ~ 600 degree yog qhov zoo tagnrho, uas tuaj yeem tau txais cov khoom zoo thiab yuav tsum tsis txhob siab dhau.
2.Thaum qhov kub siab tshaj 900 degree, cov txheej txheem sib xyaw yuav dhau mus rau theem kev hloov pauv, uas yuav cuam tshuam rau cov khoom siv kho tshuab.
