Kev kub ceev laser cladding txheej txheem tau txais kev lees paub los ntawm kev ua lag luam, thiab kev kub ceev laser cladding es tsis txhob siv cov laser cladding zoo tib yam yuav dhau los ua ib qho kev tsis pom kev hauv kev txhim kho kev lag luam technology. Txawm li cas los xij, laser cladding yog txheej txheem nyuaj. Raws li kev paub ntau xyoo, Guosheng Laser qhia txog cov ntsiab lus ntawm kev kub ceev laser cladding txheej txheem thiab cov laj thawj rau ntau yam txheej txheem teeb meem raws li hauv qab no, vam tias yuav pab tau rau feem coob ntawm cov phooj ywg kev lag luam.
Yuav ua li cas high-speed laser cladding ua haujlwm
High-speed laser cladding siv lub siab-zog laser beam kom yaj hlau hmoov txaus nyob rau hauv cov huab cua, thiab kuj melts lub matrix los ua ib tug molten pas dej ua ke.Tom qab cov molten hmoov yog ua ke nrog lub molten matrix, nws yog ceev ceev txias los tsim ib tug molten pas dej ua ke. metallurgically bonded txheej.
Cov tsis tseem ceeb ntawm kev kub ceev laser cladding txheej txheem thiab lawv lub zog ntawm cladding nyhuv
1. Laser zog
Lub zog ncaj qha cuam tshuam rau cov hmoov nplej uas tuaj yeem yaj hauv ib lub sijhawm thiab cuam tshuam rau kev ua haujlwm ntawm cladding. Thaum lwm yam kev ua haujlwm raug txiav txim siab, lub zog me me dhau, uas tuaj yeem ua rau cov hmoov tsis tiav, pitting tom qab sib tsoo, tsis muaj kev sib khi tsis txaus, thiab tsis tshua muaj txheej txheej hardness. Lub zog loj heev, nws tuaj yeem yaj lub fuse, ua rau oblique wrinkles ntawm qhov chaw.
2. Hmoov noj ntau npaum li cas
Tom qab cov hmoov ntws raws li lub laser, nws absorbs lub zog laser.Qhov loj ntawm cov hmoov, ntau lub zog laser yog absorbed.Thaum cov hmoov nplej ntau dhau lawm, lub zog laser yuav tsis txaus, cov txheej yuav tsis yaj. , thiab pitting yuav tshwm tom qab sib tsoo thiab polishing. Lub matrix yuav tsis yaj, thiab cov txheej thiab cov matrix yuav tsis raug metallurgically sib raug zoo, ua rau txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej thiab matrix yuav tsis raug metallurgically sib raug zoo, ua rau txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej thiab matrix yuav tsis yaj, thiab cov txheej txheej thiab cov matrix yuav tsis yog metallurgically sib raug zoo, ua rau txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej thiab matrix yuav tsis yaj, thiab cov txheej txheej thiab cov matrix yuav tsis raug metallurgically sib koom ua ke, ua rau cov txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej yuav tsis yaj, thiab cov txheej txheej thiab cov matrix yuav tsis yog metallurgically sib koom ua ke, ua rau cov txheej txheej txheej txheej txheej txheej txheej txheej txheej yuav tsis yaj. .
3. Kab ceev
Qhov loj dua qhov nrawm dua, qhov thinner lub cladding, thiab qhov me me ntawm cov kab nrawm, qhov tuab ntawm cov cladding.Yog tias cov kab nrawm nrawm dhau, cov substrate tsis tuaj yeem tsim lub pas dej molten, txheej thiab cov substrate tsis tuaj yeem ua tau zoo metallurgically bonded, lub yaj channel txias maj mam, tus Tsov tus tw liab ntev dhau lawm, thiab tev tawm tshwm sim. Kev nrawm nrawm me me tuaj yeem txhim kho txheej tawv tawv thiab siv hmoov.
4. Kauj ruam ib kauj ruam
Cov kauj ruam me dua, qhov ntau dua qhov sib tshooj thiab qhov zoo dua ntawm txheej txheej.Qhov loj dua cov kauj ruam, qhov sib tshooj me me thiab qhov pom tseeb ntawm cov kab txaij. Cov kauj ruam cuam tshuam rau tus nqi dilution. Thaum cov kauj ruam me me, lub zog laser irradiated ntawm lub substrate yog me me thiab tus nqi dilution tsawg. Thaum cov kauj ruam loj, ntau lub zog laser yog irradiated ntawm lub substrate thiab tus nqi dilution siab.
5. Cua muab ntim
Cov pa roj muaj ob txoj haujlwm, ib qho yog thauj cov hmoov, thiab lwm qhov yog los tiv thaiv cov txheej txheem kub thiab tiv thaiv oxidation.Yog tias cov hmoov pub mis me me dhau lawm, nws yooj yim los thaiv cov hmoov.Cov hmoov nplej. huab cua ntim loj dhau lawm, hmoov ceev ceev dhau, lub ejection loj, thiab cov hmoov siv cov hmoov yog tsawg. Feem ntau, argon tiv thaiv coatings zoo dua nitrogen thiab ua rau cov txheej txheem ntau dua.
6. Nozzle qhov siab
Yog tias lub nozzle siab dhau lawm, cov hmoov yuav nthuav tawm thiab cov hmoov siv cov hmoov yuav qis.Yog tias nws tsawg dhau, hmoov yuav yooj yim lo rau lub nozzle thaum lub sij hawm cladding txheej txheem.
Kev tshuaj xyuas ntawm cov teeb meem tshwm sim thiab ua rau thaum lub sij hawm high-speed laser cladding txheej txheem
1. Peeling
Qhov no yog vim hais tias lub matrix tsis tsim lub pas dej molten thiab tsis muaj metallurgical daim ntawv cog lus ntawm cov hmoov thiab cov matrix.Muaj yog vim li cas muaj xws li: tsis tshua muaj zog, ntau npaum li cas ntawm cov hmoov, heev ceev linear ceev, roj stain los yog electroplating txheej ntawm lub nto ntawm workpiece, thiab lwm yam.
2. Ncua tseg
Cov laj thawj ntawm cov kab nrib pleb hauv txheej muaj xws li: lub hardness ntawm lub substrate yog siab dhau (quenching, carburizing / nitrogen); lub substrate muaj ib tug qaug zog txheej; lub hardness ntawm cov hmoov yog siab dhau lawm, thiab lwm yam.Nickel-raws li hmoov yog nquag ua rau tawg; Cov kab nrib pleb kuj tuaj yeem tshwm sim thaum lub sij hawm ntau txheej cladding ntawm hmoov nrog siab hardness.
3. Poob
Yog vim li cas rau qhov tshwm sim ntawm pores nyob rau hauv lub txheej muaj xws li: xeb thiab roj stains nyob rau hauv lub substrate, impurities nyob rau hauv cov hmoov, tsis ruaj tsis khov hmoov ntws, ntau hmoov ntim, tsis txaus lub hwj chim, los yog ntau tshaj linear ceev, thiab lwm yam.

Tej yam tshwm sim yog: cov hmoov ejection siab dhau lawm; lub taub hau tooj liab kub siab dhau lawm; lub nozzle ua hauj lwm deb dhau lawm, thiab lub nozzle nto yog ntxhib heev los yog paug (polishing yog pom zoo).Lub cladding lub taub hau yog muab tso rau hauv nruab nrab los pab txo cov hmoov sticking.
8. Thaiv hmoov
Cov laj thawj muaj xws li: cov hmoov nplaum nplaum tsis raug tshem tawm hauv lub sijhawm; hmoov tsis zoo fluidity; cov hmoov muaj impurities los yog cov hmoov yog ntub dej (nws yuav tsum tau muab ci), thiab lwm yam.Thaum pub hmoov los ntawm ntau txoj kev, cov hmoov tsis sib xws ntawm txhua qhov channel yog ib qho tseem ceeb ua rau cov hmoov txhaws.
9. Muaj lub suab nrov nrov thaum cladding
Tej yam tshwm sim muaj xws li: cov hmoov muaj paug; hmoov yog damp; lub matrix tsis huv, thiab lwm yam.Kev siv zog ntau dhau yuav ua rau lub pas dej molten hlau vaporize thiab tsim cov suab nrov cladding.Cov teeb meem no yuav cuam tshuam rau corrosion kuj ntawm cov txheej.
10. Cladding sparks ya
Tej yam tshwm sim muaj xws li: tshaj linear ceev; ntau zog ceev; mismatch ntawm lub hwj chim thiab hmoov ntim; huab cua ntau dhau, thiab lwm yam.
