Hom Laser Surface Treatment Puas Muaj?

Tom qab cov tsos ntawm lub laser, tsim thiab hloov kho cov ntaub ntawv thiab workpiecento nrog laser, yog heev exquisite. Kev kho mob saum npoo ntawm cov khoom siv hlau tau kawm tau ntev, tab sis kev ua haujlwm yog clumsy thiab qias neeg, thiab kev tswj kev ua haujlwm yog ntxhib heev. Thiab kev siv lub laser beam sai sai, lub chaw ua haujlwm cua sov hauv zos, kom ua tiav cov cua kub ceev hauv zos lossis cua txias, tuaj yeem ua tiav hauv huab cua, lub tshuab nqus tsev, thiab lwm qhov chaw. Cov txheej txheem kho saum npoo ntawm cov ntaub ntawv sib txawv tuaj yeem daws tau los ntawm kev hloov cov laser tsis. Lub workpiece deformation yog me me heev thiab yog ib txoj kev tsis sib cuag. Nws tau muab faib ua kev hloov kho saum npoo av (xws li laser glazing, laser remelting, laser alloying, laser txheej), laser hloov kho, thiab kho laser tshem tawm (xws li laser tu) raws li lub hom phiaj ntawm kev kho deg.

I. Laser npav thiab laser nto txheej

1. Laser npav tshuabyog ib daim ntawv thov loj tshaj plaws hauv kev ua laser. Tam sim no muaj cov cuab yeej laser npav nyob rau hauv kev ua lag luam rau ntau yam khoom siv. Laser npav lasers feem ntau nyob ze-infrared thiab siv cov pulses ceev los tsim cov cim pom ntawm cov khoom siv. Ob qho tib si qhov tob thiab cov qauv ntawm cov cim tuaj yeem tswj tau los ntawm lub computer. Piv txwv li, kos npe rau ntawm qhov chaw ntawm cov hlau sib txawv, kos rau ntawm iav, kos rau ntawm fiber ntau optical, thiab cov ntaub ntawv sib txawv uas kos cov mem tes dav, mem tes ceev, thiab qhov kub thiab txias muaj cov qauv sib xws.

2. Laser nto woolens kho.Lub laser nruam nthwv dej tsis yog yooj yim los tswj cov khoom nto woolen, nto ntaub ntaub zoo li intensive marking yog ib qho yooj yim los tswj, raws li qhov yuav tsum tau sib txawv, thiab yuav siv tau raws li ib millisecond mem tes, picosecond mem tes, los yog femtosecond mem tes () tuaj yeem ua tiav. kev tsim kho zoo dua.

Nyob rau hauv cov khoom siv nto wool ua, nws tsim nyog hais txog yuav ua li cas los daws qhov txias dov steel phaj nto ntxhib los yog cov qauv yuav tsum tau, yog li cov neeg kuj muaj cov kev cai no rau saum npoo ntawm cov yob yob, tab sis kuj xav tau lub neej ntev kev pab cuam ntawm yob. . Txoj kev ua haujlwm zoo tshaj plaws yog siv laser pulse wool kho rau yob.

Cov txheej txheem kev ua haujlwm yog qhov zoo li no: nrog ntau txhiab mus rau kaum tawm txhiab lub sijhawm ntawm lub sijhawm thib ob pulse laser beam tsom rau ntawm qhov chaw ntawm yob, nyob rau hauv lub focal point ntawm yob nto los tsim ib tug me me solubilization pas dej ua ke, tib lub sij hawm nyob rau hauv lub focal point ntawm yob nto los ua ib tug me me solubilization pas dej ua ke, nyob rau tib lub sij hawm nyob rau hauv lub focal point ntawm yob nto. micro solubilization poolside tshuab, kom cov yaj nyob rau hauv lub pas dej solubilization kom deb li deb tau mus rau ntawm ntug ntawm lub solubilization pas dej ua ke los tsim ib ncig arc convex, nto ntawm cov me me convex thiab micro qhov yog ntxiv dag zog thiab hardened.

Qhov no txoj kev ntawm laser wool kho ntawm lub luag hauj lwm coj ib tug ntau ntawm kev tsim kho yooj yim rau cov txheej txheem ntawm dov daim ntawv.

Txheej txheej ntawm cov ntawv txias dov thiab cov khoom siv sawb yog dav siv. Rau ib qho piv txwv yooj yim, pleev xim rau lub tsheb vaj huam sib luag, qhov saum npoo ntawm daim ntawv yuav tsum tau muab sib npaug nrog "qhov" los txhim kho qhov adhesion ntawm cov xim, yog li lub tsheb vaj huam sib luag yog tshwj xeeb dov. Cold-rolled strips yog siv ntau hauv kev lag luam xws li tsheb, kev tsim kho, khoom siv hauv tsev thiab hluav taws xob, kev lag luam teeb, thiab kev tiv thaiv hauv teb chaws.

Ⅱ.Laser nto hloov kho kho

1. Laser nto theem hloov kho hardening

Cov khoom siv hlau nto hardening yog ua kom tiav "quenching" ntawm cov khoom siv, qhov dav dav txhais tau tias nyuaj ua, tab sis, nrog laser hardening khoom nto yog yooj yim heev. Raws li xav tau, hardening yuav tsum tau tsim cov theem hloov ntawm cov khoom siv.

Lub laser yog siv los yaj nto ntawm cov khoom sai sai, thiab thaum lub laser beam tawm nws solidifies sai sai. Qhov no yog ib yam ntawm nws tus kheej-quenching, qhov twg ib theem kev hloov tshwm sim nyob rau hauv lub ntiav txheej ntawm cov ntaub so ntswg ntawm lub nto ntawm cov khoom. Qhov saum npoo ntawm cov khoom muaj cov pob zeb me me, uas ua rau lub ntsej muag tawv.

2. Laser nto alloying kev kho mob

Cov txheej txheem uas siv lasers los ua kom sov qhov chaw ntawm ib cheeb tsam ntawm cov khoom mus rau ib tug tej yam kub los yog ua ib tug nyias melting txheej, hloov cov tshuaj muaj pes tsawg leeg ntawm nto los ntawm diffusion los yog ntxiv alloying ntsiab los yog tshuaj tiv thaiv los txhim kho cov neeg kho tshuab, lub cev. thiab chemical zog ntawm cov khoom nto. Nws muaj qhov zoo ntawm kev ua haujlwm hauv zos, tsis tshua muaj matrix deformation, tsis muaj kev puas tsuaj rau matrix khoom, kev ua haujlwm siab, thiab cua kub ceev. Nws yog tshwj xeeb tshaj yog haum rau qhov tseem ceeb ntawm lub workpiece, xws li pwm seam kab, valve tappet, thiab lub zos nto ntawm lub camshaft.

Laser nto alloying tsis tsuas yog txhim kho "lub caj dab" ib feem ntawm lub neej ua haujlwm tab sis kuj txo cov txheej txheem thiab txuag cov ntsiab lus alloying.

3. Laser nto txheej kho

Laser txheej yog zoo ib yam li laser alloying nyob rau hauv uas ib co lwm yam alloy khoom yog fused rau hauv lub matrix thaum lub laser yog cua sov nws.

Ntxiv nrog rau kev sib txuas ntawm metallurgical ntawm cov matrix thiab cov khoom siv melted, cov khoom siv yog tsis tshua muaj diluted los ntawm cov khoom siv matrix thiab yeej ua rau nws cov khoom qub tsis hloov pauv.

Piv nrog rau laser alloying, laser txheej tuaj yeem tswj tau qhov sib xyaw thiab tuab ntawm cov txheej txheej saum npoo, thiab tuaj yeem tau txais cov txheej txheej txheej txheej sib txawv ntawm cov substrate, thiaj li ua tiav lub hom phiaj ntawm hnav tsis kam thiab corrosion kuj.

4. Laser ntxuav

Kev siv lub zog loj laser beam irradiation workpiece nto, kom cov av ntawm cov av, xeb, los yog txheej instantaneous evaporation los yog tev, kev kub ceev thiab zoo tshem tawm cov pa phem los yog coatings. Laser tu belongs rau qhuav tu, tsis xav tau cov organic solvents, tsis muaj cov kua emissions pov tseg, thiab tsawg residue, yuav tsis ua rau ib puag ncig muaj kuab paug, thiab yuav ua tau zoo tshem tawm lwm txoj kev nyuaj rau tshem tawm huv si adsorption ntawm lub submicron hais. Cov cuab yeej siv tau yooj yim, zoo controllability, yooj yim-rau-xaiv positioning precision tu, yooj yim rau tej thaj chaw deb tswj tu nyuaj mus cuag los yog txaus ntshai qhov chaw.

Feem ntau muaj 4 txoj hauv kev ntawm laser tu:

(1) Laser qhuav tu txoj kev, uas yog, kev siv cov pulsed laser ncaj qha hluav taws xob decontamination;

(2) Laser plus kua zaj duab xis txoj kev, uas yog, ua ntej tso ib txheej ntawm cov kua zaj duab xis rau saum npoo ntawm lub substrate, thiab ces siv ib tug laser los ua cov kua zaj duab xis tawg decontamination;

(3) Laser plus inert gas txoj kev, uas yog, tib lub sij hawm ntawm laser hluav taws xob, nrog inert gas tshuab mus rau lub workpiece nto, thaum cov av yog tev tawm ntawm qhov chaw, cov roj nyob deb ntawm qhov chaw, kom tsis txhob huv si. deg pollution thiab oxidation;

(4) Siv lub laser los plam cov av, thiab tom qab ntawd siv cov tshuaj tsis muaj tshuaj lom los ua kom tsis muaj paug.
