Muaj pes tsawg txoj hauv kev rau hlau phaj cladding?

Nrog rau kev loj hlob sai ntawm kev lag luam niaj hnub thiab kev txo cov peev txheej, ib daim hlau hlau tsis tuaj yeem ua tau raws li cov neeg xav tau. Hlau clad daim hlau tsis tsuas yog txo qis kev siv cov hlau tsis tshua muaj thiab txo cov nqi tsim khoom, tab sis kuj muaj qhov zoo ntawm ob qho tib si substrates thiab cov txheej txheem sib xyaw, uas qhia txog kev lag luam zoo heev, yog li dhau los ua cov khoom lag luam zoo tshaj plaws.

Clad phaj yog cov khoom sib xyaw ua ke tsim los ntawm cov hlau nplaum sib txuas nrog cov khoom sib txawv ntawm qhov sib cuam tshuam siv ntau yam kev siv thev naus laus zis.

Feem ntau, ib lub phaj ntawm ib lub hlau yog them nrog lub phaj ntawm lwm cov hlau kom txuag tau cov peev txheej thiab txo cov nqi yam tsis muaj kev txo qis kev siv (kev tiv thaiv corrosion, kev siv lub zog, thiab lwm yam).

Los ntawm kev xaiv cov khoom tsim nyog thiab tsim qauv tsim, clad hlau daim hlau tuaj yeem txhim kho cov thermal expansion, zog, toughness, hnav tsis kam, corrosion kuj, hluav taws xob zog, magnetic zog thiab ntau lwm yam khoom ntawm ib cov ntaub ntawv hlau.

 

Explosive Cladding

Kuj hu ua explosive welding, hais txog stacking ob los yog ntau dua hlau phaj ua ke thiab tom qab ntawd siv qhov cuam tshuam ntawm kev tawg los ua ib qho metallurgical bonding ntawm cladding thiab lub hauv paus phaj.

Kuj hu ua dov bonding, yog ib lub tshuab ua hlau yas.

Tom qab ntxuav qhov chaw ntawm ob los yog ntau tshaj cov ntaub ntawv hlau yuav tsum tau laminated thiab stacking lawv ua ke, lub siab ntawm dov zeb yog siv los rhuav tshem zaj duab xis saum npoo ntawm cov hlau yuav tsum tau laminated, nthuav tawm cov hlau tshiab thiab du, yog li ua tiav kev sib raug zoo ntawm ob hlau.

Classification ntawm Roll Bonding

  Kub Roll Bonding

Cov hlau sib sau ua ke yog rhuab mus rau qhov ntsuas kub thiab xa mus rau lub tshuab dov. Nyob rau hauv qhov kub thiab txias siab, cov billets undergo yas deformation, tso cai rau cov hlau tsis sib xws yuav tsum ruaj welded ua ke.

Txias Roll Bonding

Nws yog feem ntau muab faib ua peb kauj ruam:

nto pretreatment ua ntej dov + dov nrog ib tug npaum li cas ntawm txo + diffusion tshav kub kho tom qab dov

Nws yog ib qho kev sib xyaw ua ke tsim los ntawm kev sib xyaw kub dov. Piv nrog rau cov kub dov sib xyaw, vim qhov kub ntawm qhov sib tov qis, nws tuaj yeem zam qhov kev hloov pauv, kev hloov microstructure thiab brittle hlau compound tsim uas tsis haum rau kev sib txuas ntawm cov ntaub ntawv hlau. Lub thickness ntawm cov ntaub ntawv txias-kuav los tiag yog sib xws, qhov chaw sib txuas yog tiaj tus thiab tsis muaj yoj duab, thiab cov khoom ua tau zoo yog ruaj khov.

Hla Shear Roll Bonding

Nws rolls hlau los ntawm kev hloov lub dov ceev ntawm lub sab sauv thiab sab rolls kom cov menyuam linear ceev sib txawv.

Los ntawm txoj kev no, cov hlau nyuaj yog feem ntau sib tw nrog cov menyuam ceev, thiab cov hlau softer yog txuam nrog cov menyuam yaus.

Nqus Rolling Cladding (VRC)

Nws ua ke kub dov nrog lub tshuab nqus tsev electron beam vuam (EBW) thev naus laus zis. Lub interface ntawm cov phaj sib xyaw yog nyob rau hauv lub tshuab nqus tsev siab, tsis muaj oxidation ntawm lub interface thaum lub sij hawm cua sov txheej txheem, thiab lub interface bonding kev ua tau zoo kuj siab.

 Ua kom muaj kev sib koom ua ke ntawm cov khoom hlau kom ua tiav qhov zoo tshaj plaws ntawm cov khoom siv

 Txuag kev siv cov hlau zoo nkauj thiab txo cov nqi

 titanium clad hlau

 tooj liab clad steel

 titanium clad zinc

 titanium clad npib tsib xee

 nickel clad hlau

 tooj liab clad aluminium

 nickel clad tooj liab

Nws yog dav siv hauv roj av, tshuaj, shipping, metallurgy, hluav taws xob, kev txuag dej, kev thauj mus los, kev tiv thaiv ib puag ncig, khoom noj khoom haus, tshuaj thiab lwm yam kev lag luam.
