Kev kho deg rau Laser Cladding 

Laser cladding thev naus laus zis yog qhov kev hloov kho saum npoo av tshiab uas tau tshwm sim hauv xyoo 1970 nrog kev txhim kho ntawm lub zog lasers.Nws txhais tau hais tias laser nto cladding tshuab yog txheej txheej txheej uas yog tsim los ntawm cov cua kub ceev thiab melting alloy los yog ceramic hmoov nrog substrate nto nyob rau hauv qhov kev txiav txim ntawm laser beam, thiab ces nws tus kheej zoo siab txias tom qab lub beam raug tshem tawm los tsim ib tug txheej txheej. nrog tsawg heev dilution tus nqi thiab metallurgical bonding nrog cov khoom siv substrate.Qhov no yog ib txoj kev ntxiv dag zog rau saum npoo uas txhim kho qhov hnav tsis kam, corrosion kuj, kub tsis kam, oxidation tsis kam thiab hluav taws xob cov yam ntxwv ntawm lub substrate nto.

Piv txwv li, tom qab laser cladding ntawm tungsten carbide ntawm 60 steels, lub hardness nce mus txog 2200 HV los yog ntau tshaj, thiab hnav tsis kam yog li 20 npaug ntawm lub hauv paus 60 steel.Tom qab laser cladding ntawm CoCrSiB alloy nyob rau saum npoo ntawm Q235 steel, nws hnav tsis kam yog muab piv nrog corrosion kuj ntawm nplaim spraying, thiab qhov qub tau pom tias muaj ntau dua li yav tas los.

Laser cladding thev naus laus zis tso cai rau cov khoom tso tawm kom raug thiab xaiv nrog cov cua sov me me rau hauv qab substrate.Tsim no mechanical bond ntawm substrate thiab txheej yog ib qho ntawm cov txheej txheem vuam zoo tshaj plaws muaj.

Khoom siv rau Laser Cladding

Qhov zoo ntawm ib Glance

• Melt-coated khaubncaws sab nraud povtseg yog ntau resistant rau corrosion tshaj thermal spray txheej
• Cov tshuab zoo tshaj plaws rau txheej txheej txhua yam
• Cov cua kub qis qis ua rau muaj qhov cuam tshuam rau qhov chaw nqaim (EHLA mus txog 10µm)
• Ua kom muaj kev pabcuam lub neej ntawm cov khoom hnav
• Yuav siv tau nrog ntau yam ntaub ntawv, suav nrog kev cai alloy lossis hlau matrix composite (MMC) tsim substrates thiab txheej
• Flexibility nyob rau hauv cov khoom xaiv (hlau, ceramics, txawm polymers)
• High nto zoo thiab tsis muaj warpage, yuav tsum tau me ntsis kom tsis muaj kev kho mob tom qab
• Lub sijhawm luv luv thiab lub zog ua haujlwm siab ntawm cov txheej txheem laser cladding
• Yooj yim automation thiab kev koom ua ke rau hauv CNC thiab CAD / CAM ntau lawm ib puag ncig
• Me me lossis tsis muaj porosity hauv qhov tso nyiaj (> 99.9% ntom)

Kev siv ntawm Laser Cladding Technology

Laser cladding tshuab muaj ntau yam kev siv, thiab koj tuaj yeem tshuaj xyuas cov ntawv thov kev lag luam uas muaj los xyuas kom meej tias lawv haum rau koj qhov kev siv qhov xwm txheej.Xwb, koj tuaj yeem ua tau mus saib peb nplooj ntawv laser cladding yog xav paub ntxiv.Laser cladding tshuab tuaj yeem siv rau kev tsim khoom sai, kho ib feem thiab txhim kho saum npoo, thiab muaj ntau daim ntawv thov suav nrog, tshwj xeeb, hauv tsheb, FMCG, kev kho mob thiab kev lag luam.Nws yog feem ntau siv los kho dua tshiab, tsim thiab kho qhov chaw xws li cov cuab yeej, shafts, hniav, turbines, cov cuab yeej drilling, thiab lwm yam. Cov hauv qab no yog qee qhov kev siv ntau yam:

• Aerospace turbine hniav thiab kho
• Kev kho cov kabmob
• Ntxuam phau ntawv xov xwm thiab chaw foob (kev lag luam cement)
• Turbocharger impellers
• Cov cuab yeej drilling
• Agricultural machinery
• Exhaust li qub
• Piston pas nrig
• Thaum tshav kub kub exchangers
• Cov txheej txheem kub kub, hardness thiab corrosion kuj, valve daim di ncauj thiab rooj zaum (cobalt 6)

Disadvantages ntawm ib Glance

• Thaum laser cladding muaj ntau qhov zoo, muaj qee qhov tsis zoo rau kev siv tshuab, suav nrog:
• Tus nqi siab ntawm cov khoom siv laser cladding
• Cov cuab yeej loj txhais tau hais tias nws feem ntau tsis tuaj yeem nqa tau, txawm hais tias muaj cov kev daws teeb meem portable
• Kev tsim cov nqi siab tuaj yeem ua rau tawg (txawm hais tias qee cov ntaub ntawv no tuaj yeem raug tshem tawm nrog kev tswj xyuas thermal ntxiv, xws li preheating thiab post-deposition cooling controls) Cov txheej txheem laser cladding heats thiab txias heev, mus txog 1012 ° C / s.Vim qhov sib txawv ntawm qhov kub thiab txias gradients thiab coefficients ntawm thermal expansion ntawm clad thiab substrate cov ntaub ntawv, ntau yam defects yuav tsim nyob rau hauv lub clad txheej, feem ntau xws li porosity, cracking, distortion thiab nto unevenness.

Kev ntsuas qhov zoo ntawm Laser Cladding Txheej

Nws muaj ob yam uas yuav tsum xav txog:

1Macroscopically, tshuaj xyuas cov duab ntawm clad channel, nto unevenness, tawg, porosity thiab dilution tus nqi.

2Nyob rau qib microscopic, kev tsim cov koom haum zoo thiab muaj peev xwm muab cov khoom tsim nyog raug tshuaj xyuas.Tsis tas li ntawd, hom thiab kev faib tawm ntawm cov tshuaj lom neeg ntawm cov txheej txheej txheej txheej yuav tsum tau txiav txim siab, thiab kev saib xyuas yuav tsum tau them nyiaj los tshuaj xyuas seb qhov xwm txheej ntawm cov txheej txheem hloov pauv puas yog metallurgical bonding, thiab kev kuaj lub neej zoo yuav tsum tau ua yog tias tsim nyog.

Surface finishing tuav functional as well as aesthetic important for industrial parts.Nrog rau kev lag luam nce mus sai sai, cov kev cai kam rau ua tau dhau los ua nruj dua thiab yog li kev ua tiav zoo dua yog xav tau rau cov khoom lag luam siab.Cov khoom uas muaj kev txaus siab zoo li muaj txiaj ntsig zoo hauv kev ua lag luam.Kev zoo nkauj sab nrauv tiav tuaj yeem ua qhov sib txawv loj hauv ib feem ntawm kev ua lag luam.

Prolean Tech cov kev pabcuam ntog tiav muab cov qauv nrog rau qhov nrov nto tiav rau qhov chaw.Peb cov tshuab CNC thiab lwm yam txheej txheem txheej txheej muaj peev xwm ua tiav cov kev ua haujlwm nruj thiab cov khoom zoo, zoo ib yam rau txhua yam ntawm qhov chaw.Tsuas yog upload kojCAD cov ntaub ntawvkom ceev, pub dawb hais thiab kev sab laj txog cov kev pabcuam cuam tshuam.
