◆ Laser cladding thev naus laus zis yog kev siv lub siab ua lub zog laser nqaj irradiation, txhawm rau txheej txheej txheej ntawm cov khoom nyob rau saum npoo ntawm lub cev nrog cov khoom siv tshwj xeeb lub cev, tshuaj lom neeg lossis tshuab, los ntawm kev yaj sai, nthuav dav thiab lub zog; los ua cov ntawv tshiab sib txawv ntawm cov substrate, txhawm rau kom ua rau qhov tsis muaj qhov ua tiav siab-matrix. Raws li qhov ua tau zoo ntawm qhov haujlwm ntawm lub workpiece, lase tuaj yeem clad ntau yam ntawm cov khoom siv hlau, cov ntaub ntawv siv hlau, thiab lwm yam, kom cov txheej txheej saum npoo muaj cov yam ntxwv ntawm kev tiv thaiv tshav kub, tiv thaiv corrosion, hnav tsis kam, tiv thaiv kev txhuam, los tiv thaiv oxidation thiab tsis sib nqus; kom cov khoom muaj cov qauv thiab kev ua tiav uas qhov kev kho ib qho tsis muaj.
◆ Laser cladding tshuab belongs rau kev tsim cov tshuab ntxiv ntawm cov hlau thiab nws cov ntaub ntawv sib xyaw. Nws yog qhov tseem ceeb txhawb nqa technology ntawm laser txhim kho kev tsim, laser remanufacturing thiab laser 3D manufacturing. Tsis tas li ntawd, laser cladding thev naus laus zis yog kev tsim cov tshuab tsim kev lag luam uas tuaj yeem ua tau raws li cov kev xav tau ntawm kev sib koom ua ke ntawm kev sib sau. Nws tuaj yeem muab ob qho tib si muab kev txiav txim siab rau qhov ua kom raug thiab kev ua haujlwm siab. Nws koom nrog cov thev naus laus zis thev naus laus zis, thev naus laus zis thev naus laus zis, thev naus laus zis tswj thev naus laus zis thiab cov khoom siv thev naus laus zis thiab ntau lwm cov thev naus laus zis tshiab, thiab tau maj mam dhau los ua cov thev naus laus zis uas tuaj yeem paub txog kev tsim khoom ntse. Ntxiv mus, laser cladding tuaj yeem daws cov teeb meem uas cov txheej txheem tsim kev lag luam tsis tuaj yeem ua tiav, thiab yog cov thev naus laus zis thev naus laus zis txhawb nqa thiab txhawb nqa los ntawm lub xeev.
Sib piv nrog ntau hom kev kho tshuab saum npoo av, laser cladding thev naus laus zis muaj cov yam ntxwv zoo li nram no:
1.Laser cladding tuaj yeem tsim cov tshav kub me me cuam tshuam rau ntawm qhov chaw ua haujlwm thiab lub workpiece deformation yog me me.
2.Metallurgical tsevneeg tuaj yeem paub txog nruab nrab ntawm txheej txheej thiab cov khoom hauv txheej, thiab cov dej khov kho ntawm cov khoom siv cladding yog tsawg.
3.Qhov txheej txheej muaj cov hmoov nplej zoo thiab cov qauv kev cog lus, uas tuaj yeem tau txais cov hardness ntau dua, hnav tsis kam thiab tiv taus corrosion.
4.Xaiv cov khoom ua haujlwm me me hloov maj mam tuaj yeem ua tiav, thiab tus nqi kho yuav txo tau.
5.Powder cov khoom siv system muaj qhov ua kom tau siab, feem ntau ntawm cov pa thiab cov ntawv hlau tshwj xeeb cov ntaub ntawv tuaj yeem lo rau saum npoo ntawm cov hlau.
◆ Tom qab xyoo caum ntawm kev txhim kho, laser cladding tshuab tau siv dav hauv aerospace, roj av, nkoj tsim, kev tsim kho tshuab thiab chaw tsim hluav taws xob nuclear los ntawm chav kuaj mus rau kev thov siv.
1. Aerospace
Muaj qhov kev lag luam loj heev rau kev kho dua tshiab ntawm aero-cav hniav tuaj. Cov hniav ntswj muaj ntau yam ntawm cov ntaub ntawv thiab cov ntsiab lus siab hauv tshuab, thiab kho cov hniav yuav tsum tau ua haujlwm ntau hauv cov kev ua haujlwm ntawm cov khoom siv kho kho, kev tshawb pom qhov tsis zoo thiab cov cuab yeej ntsuas lub neej. Tsis tas li ntawd, kev lag luam kev lag luam dav dav hauv nroog tseem muaj kev tso siab rau kev siv txawv teb chaws rau qee qhov tseem ceeb, yog li kev ncua sij hawm txij nkawm ntawm cov dav hlau yuav tsum tau siv nyiaj ntau heev los yuav qhov chaw tshiab ntawm txawv teb chaws.
2. Kev tshawb nrhiav roj av
Hauv kev lag luam petrochemical, vim yog lub sijhawm ua haujlwm hnyav nyob ib puag ncig ntawm cov cuab yeej siv, nws yuav ua rau muaj kev cuam tshuam loj heev thiab hnav hnyav ntawm qhov chaw, uas yuav ua rau kom tiav cov khoom seem thiab kim, xws li laum tsoo, tsis yog- sib nqus laum dab tshos thiab nruab nrab.
3. Coal mining
Hauv kev lag luam thee, vim yog qhov chaw ua haujlwm hnyav, qhov yuav tsum ua tau zoo ntawm kev ntsuam xyuas cov tshuab zeb thee. Lub ntsiab tsis ua haujlwm ntawm hydraulic kem yog cov txheej kauv thiab cov tev pleev xim. Kev siv cov pa hluav taws xob muaj kuab paug rau txheej txheem ntau, thiab electroplating yog ib qho ntawm cov thev naus laus zis kom maj mam txwv hauv peb lub teb chaws. Yog li ntawd, kev siv laser cladding thev naus laus zis rau hydraulic kem qhov rooj muaj qhov kev lag luam loj; nws tseem yog ib hom kev txhawb nqa hauv tebchaws, ib puag ncig tus phooj ywg, rov ua dua tshiab thiab cov cuab yeej siv siab, uas tuaj yeem hloov cov txheej txheem electroplating qub.
4. Kev lag luam fais fab fais fab
Nyob rau hauv qhov xwm txheej ntawm kev ua haujlwm siab ceev, lub rotor phau ntawv xov xwm ntawm lub raj cua hauv lub tshuab hluav taws xob muaj qhov teeb meem ntawm hnav. Tsis tas li ntawd, cavitation feem ntau tshwm sim thaum kawg thiab theem kawg lub ntsej muag ntxig ntawm cov cua turbine tau ua haujlwm ntev ntev nyob rau hauv qhov xwm txheej ntawm qhov kub. Cov cua turbine yog cov cuab yeej siv loj thiab tsis yooj yim thauj, yog li nws xav tau lub siab ntseeg siab laser hauv-kho kev kho tshuab.
Tsis tas li ntawd, laser cladding kuj tseem siv tau rau hauv cov hlau thiab cov hlau metallurgy, tsheb, siv tshuab, pwm tsim thiab nkoj tsim thiab lwm yam kev lag luam, uas muaj ntau cov ntawv thov kev cia siab.
