Cov txheej txheem high-speed laser cladding tau raug lees paub los ntawm kev ua lag luam. Kev hloov ntawm cov laser cladding zoo tib yam los ntawm kev kub ceev laser cladding yuav dhau los ua ib qho kev tsis pom kev hauv kev lag luam thev naus laus zis.Txawm li cas los xij, laser cladding yog cov txheej txheem nyuaj. Txhawm rau pab feem ntau ntawm kev kub ceev laser cladding cov neeg siv paub cov txheej txheem sai, raws li ntau xyoo ntawm kev paub, Guosheng Laser tau sau cov ntsiab lus tseem ceeb ntawm kev paub thiab ntau yam txheej txheem teeb meem ntawm kev kub ceev laser cladding txheej txheem. Cov laj thawj tau sau tseg raws li hauv qab no. Kuv vam tias nws tuaj yeem pab tau rau feem coob ntawm cov npoj yaig hauv 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 hmoov melted thiab melted matrix yog ua ke, lawv tau txias sai heev los ua ib tug 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 hwj chim loj heev, nws muaj peev xwm yaj lub fuse, uas ua rau oblique wrinkles ntawm qhov chaw.Lub hwj chim ncaj qha cuam tshuam tus nqi ntawm cov hmoov uas yuav yaj tau ib lub sij hawm thiab cuam tshuam rau cladding efficiency. 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
Thaum cov hmoov ua tau raws li lub laser, nws absorbs lub zog laser. Qhov ntau dua cov hmoov, ntau lub zog laser yog absorbed. Thaum cov hmoov nplej loj dhau lawm, nws yuav ua rau lub zog laser tsis txaus, cov txheej yuav tsis yaj, thiab pitting yuav tshwm sim tom qab sib tsoo thiab polishing. Lub substrate tsis tuaj yeem yaj, cov txheej thiab cov substrate tsis tuaj yeem ua tiav metallurgical bonding, ua rau muaj teeb meem ntawm txheej txheej. Yog tias cov hmoov ntau ntau, cov hmoov siv cov hmoov yog tsawg. Yog tias cov hmoov ntau me me, cov hmoov siv hmoov yog siab.
3. Kab ceev
Qhov siab dua qhov linear tshaj tawm, qhov thinner lub cladding, thiab qhov qis tshaj ntawm linear tshaj tawm, lub thicker lub cladding. Kev nrawm nrawm nrawm yuav tiv thaiv los ntawm kev tsim lub pas dej molten ntawm lub matrix, thiab cov txheej txheem thiab cov matrix tsis tuaj yeem ua ke zoo hauv metallurgy. Yog hais tias lub fuse txias qeeb, tus Tsov tus tw liab ntev dhau lawm, thiab qhov tshwm sim tshwm sim tshwm sim. Tsawg linear ceev tuaj yeem txhim kho txheej hardness thiab hmoov siv.
4. Kauj ruam
Qhov me me ntawm cov kauj ruam, qhov loj dua tus ncej puab thiab qhov zoo ntawm txheej txheej; Qhov loj dua qhov stepping, qhov me me ntawm lub puab tsaig thiab qhov pom tseeb ntawm cov txheej streaks. Cov kauj ruam cuam tshuam rau tus nqi dilution. Thaum lub kauj ruam me me, lub zog laser irradiated ntawm lub matrix yog me me thiab tus nqi dilution tsawg. Thaum lub kauj ruam loj, ntau lub zog laser yog irradiated rau lub matrix, thiab tus nqi dilution yog siab.
5. Cua muab ntim
Cov roj muaj ob txoj haujlwm, ib qho yog thauj cov hmoov, thiab lwm qhov yog los tiv thaiv cov txheej txheem kub kom tiv thaiv oxidation. Yog tias cov hmoov xa khoom roj tsawg dhau, nws yooj yim rau ntsaws cov hmoov. Yog hais tias cov hmoov xa khoom roj ntau dhau lawm, cov hmoov nplej ceev dhau, cov ejection loj, thiab cov hmoov siv cov hmoov yog tsawg. Feem ntau, argon txheej tiv thaiv zoo dua li nitrogen, thiab txheej txheej zoo dua.
6. Nozzle qhov siab
Yog hais tias lub nozzle siab dhau lawm, cov hmoov sib txawv yog qhov loj, thiab kev siv cov hmoov yog tsawg. Yog tias qis dhau lawm, txheej nozzle yog yooj yim los lo hmoov.
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 lub matrix tsis tsim lub pas dej molten, thiab cov hmoov tsis metallurgically ua ke nrog cov matrix. Tej yam tshwm sim yog: lub hwj chim tsawg dhau; Hmoov ntau dhau; Kab nrawm dhau; Muaj roj lossis electroplating ntawm qhov chaw ua haujlwm.

7. Nozzle sticks hmoov
Qhov ua tau yog: Cov hmoov ejection siab dhau lawm; Lub taub hau tooj liab kub siab dhau lawm; Lub nozzle ua haujlwm nrug tsawg dhau; Lub nozzle nto yog ntxhib dhau los yog muaj kuab paug (kev kho polishing pom zoo). Qhov chaw tawm ntawm qhov chaw ntawm lub taub hau cladding yog qhov tsim nyog los txo cov nplaum hmoov phenomenon.
8. Thaiv hmoov
Qhov ua tau yog: Cov hmoov nplaum nplaum tsis raug tshem tawm raws sijhawm; Hmoov fluidity tsis zoo; Hmoov impurities los yog hmoov ntub dej (kom qhuav), thiab lwm yam. Thaum lub sij hawm ntau txoj kev noj cov hmoov, kev noj tsis sib npaug ntawm txhua txoj kev yog ib qho tseem ceeb ua rau cov hmoov thaiv.
9. Muaj lub suab nrov nrov thaum cladding
Cov ua tau yog: hmoov paug; Cov hmoov yog damp; Lub matrix tsis huv, thiab lwm yam. Ntau lub zog ntom ntom kuj tuaj yeem ua rau hlau gasification hauv lub pas dej molten, ua rau lub suab nrov cladding. Cov teeb meem no yuav cuam tshuam rau corrosion kuj ntawm cov txheej.
10. Lub cladding sparks txaws
Qhov ua tau yog: Tshaj tawm tshaj tawm; Lub zog ceev yog loj dhau; Lub zog thiab hmoov ntau tsis sib xws; Cua ntws loj dhau lawm.
11. Cov hmoov tsis ruaj tsis khov, ua rau cov txheej tsis sib xws
Cov laj thawj rau cov hmoov tsis ruaj khov yog: Cov khoom siv scraper hnav; Hmoov xa khoom channel raug thaiv; Lub airflow tsawg dhau; Lub nplhaib sealing ntawm cov hmoov feeder tsis zoo kaw los yog cov hmoov yeeb nkab puas, ua rau huab cua to.
12. Txo cladding efficiency (thinner txheej thickness)
Tej yam ua tau: Kev sib kis ntawm daim iav tiv thaiv; Scraper hnav; Qhov kev ua haujlwm deb tsis haum; Cov hmoov av yog av loj; Cov hmoov ntws yog ntxhib; Laser zog poob, thiab lwm yam.
