Laser cladding kho tshuabyog ib hom khoom siv deg hloov kho tshuab. Nws yog kev siv laser siab zog ceev beam, los ntawm lub laser ua system nyob rau hauv kev tswj ntawm cov zauv tswj, lub matrix nto los tsim ib tug heev nyias txheej ntawm micro yaj txheej. Self-fusing alloy hmoov nrog cov muaj pes tsawg leeg, xws li npib tsib xee puag, cobalt puag thiab hlau puag alloy, yog ntxiv nyob rau hauv ib tug preset los yog synchronous txoj kev, thiaj li hais tias lawv sib npaug zos rau ntawm qhov chaw nyob rau hauv lub molten lub xeev thiab mus txog ib tug predetermined. thickness, tsim ib tug zoo metallurgical daim ntawv cog lus nrog cov micro-molten puag hlau cov ntaub ntawv, thiab tsuas yog ib tug me me dilution ntawm ib leeg. Nyob rau hauv lub tom ntej solidification txheej txheem, ib tug haumxeeb cladding txheej txheej nrog predetermined tshwj xeeb cov khoom uas yog kiag li txawv los ntawm lub matrix yog tsim nyob rau hauv lub nto ntawm ib feem, uas muaj peev xwm hloov tag nrho cov nto ntawm cov khoom, thiab thaum kawg ua rau lub nto ntawm pheej yig. Cov khoom tau txais kev hnav tsis tshua muaj siab, corrosion tsis kam, kub tsis kam thiab lwm yam khoom.
Raws li cov khoom sib txawv ntxiv txoj kev, laser cladding txoj kev tau muab faib ua preset method thiab synchronous hmoov pub txoj kev. Raws li lub npe implies, cov khoom pre-coated yog muab tso rau ntawm pre-kho substrate nto los ntawm txau los yog kev sib txuas, thiab ces remelted los ntawm laser beam hluav taws xob ua ntej kev kho cua sov tsim nyog; Synchronous hmoov pub mis yog txau cov hmoov ncaj qha rau ntawm lub pas dej ua ke ntawm lub xov tooj ntawm tes tsim los ntawm cov hluav taws xob laser rau saum npoo ntawm cladding substrate tom qab pretreatment, thiab txheej yog tsim nyob rau hauv ib lub sij hawm. Synchronous hmoov pub mis yog txoj kev loj hlob ntawm laser cladding tshuab, uas tuaj yeem siv tag nrho cov laser zog, tswj cov txheej txheem tsis, txhim kho kev tsim khoom thiab txheej txheej zoo. Txawm li cas los xij, synchronous hmoov xa tuaj kuj muaj qhov yuav tsum tau ua rau qhov loj me thiab fluidity ntawm cov hmoov, uas yuav tsum tau txiav txim siab raws li qhov xwm txheej tshwj xeeb.
Laser cladding cov ntaub ntawv thiab cov khoom
Hauv kev kawm ntawm laser cladding, kev tshawb fawb cov ntaub ntawv yog ib qho tseem ceeb cov kev taw qhia, tsom mus rau lub compatibility ntawm ntau yam additives cov ntaub ntawv thiab qhov chaw nyob rau hauv daim ntawv thov scenarios. Hlau raws alloy hmoov yog haum rau qhov chaw uas yuav tsum tau nyob rau hauv lub zos hnav kuj thiab yog yooj yim deformed. Cobalt-based alloy hmoov muaj qhov kub thiab txias tsis kam, hnav tsis kam thiab corrosion kuj, thiab feem ntau siv hauv petrochemical thiab metallurgical teb. Cov ntaub ntawv ceramic muaj lub zog siab ntawm qhov kub thiab txias, zoo thermal stability, tshuaj lom neeg ruaj khov, thiab feem ntau yog siv rau hauv cov khoom uas yuav tsum tau hnav tsis kam, corrosion kuj, kub tsis kam thiab oxidation tsis kam. Vim hais tias ib qho khoom siv nyob rau hauv rooj plaub ntawm zawv zawg hnav, cuam tshuam hnav thiab abrasive hnav hnyav yuav tsis ua raws li qhov yuav tsum tau ua ntawm kev siv cov xwm txheej. Yog li ntawd, kev sib xyaw siv cov hlau txheej thiab ceramic txheej tau dhau los ua qhov kev tshawb fawb hotspot, muaj cov hlau, titanium alloy thiab aluminium alloy nto laser cladding ntawm ntau yam kev tshawb fawb ceramic los yog cermet txheej.
Piv nrog rau lwm cov kev kho mob saum npoo av, laser cladding muaj nws tus yam ntxwv thiab zoo:
Cov cua txias ceev yog ceev (txog 10^6 degree C / s), uas belongs rau cov txheej txheem solidification, thiab nws yog ib qho yooj yim kom tau txais cov qauv siv lead ua zoo los yog tsim cov theem tshiab uas tsis tuaj yeem tau txais hauv lub xeev sib npaug, xws li theem tsis ruaj khov. thiab amorphous xeev. Lub dilution tus nqi ntawm cov txheej yog tsawg dua 5%, thiab lub matrix yog ruaj khov los ntawm metallurgy los yog interfacial diffusion, kom tau ib tug zoo cladding txheej nrog controllable txheej muaj pes tsawg leeg thiab dilution degree, thiab xyuas kom meej tias cov kev ua tau zoo tsis degenerate. Nrog lub zog siab ceev cladding, lub cua kub ceev ceev, thiab cov tswv yim tshav kub, kub kub thaj tsam thiab distortion ntawm lub substrate yog me me. Kev xaiv hmoov yog yuav luag tsis txwv, thiab siab melting point alloys tuaj yeem tso rau saum npoo ntawm cov hlau uas tsis tshua muaj melting point. Lub thickness thiab hardness ntau yam ntawm cladding txheej yog loj, thiab txheej cladding muaj tsawg dua microscopic defects thiab kev ua tau zoo dua. Cov txheej txheem txais kev tswj tus lej, tsis muaj kev sib cuag, kev ua haujlwm tsis siv neeg, yooj yim, yoog raws, muaj zog controllability.
Kev thov ntawm laser cladding hauv kev lag luam
Laser cladding no kho thiab remanufacturing txheej txheem, ib tug yog ntxiv dag zog rau lub luag hauj lwm, yuav txhim khu kev ua tau zoo ntawm substrate los ntawm lub cladding txheej; Qhov thib ob yog kev kho lub luag haujlwm, uas yog qhov tseem ceeb hauv kev kho lub qhov thiab cov kab nrib pleb ntawm qhov chaw ntawm cov khoom siv, thiab kev kho dua tshiab ntawm geometric loj thiab kev ua haujlwm ntawm cov khoom hnav, uas muaj txiaj ntsig zoo heev rau daim ntawv thov yuav luag tag nrho. machinery manufacturing kev lag luam.
Hauv cov pob zeb mining, tshuaj lom neeg kev lag luam, metallurgy, hluav taws xob fais fab, cement thiab lwm yam khoom siv kho tshuab kev lag luam, roj turbine rotor phau ntawv xov xwm thiab hniav, dov cov phau ntawv journal, steel zeb arch, thiab lwm yam, yuav muaj hnub nyoog thiab kev puas tsuaj nrog kev siv sijhawm. Vim lub sij hawm ntev raug ntawm cov khoom no mus rau qhov kub thiab txias thiab high-pressure gas thiab corrosive xov xwm, ua ke nrog cov neeg kho tshuab kev nyuaj siab los ntawm ntim load, feem ntau ntawm cov kev puas tsuaj tshwm sim nyob rau hauv lub nto los yog nto, thiab cov tsis ua hauj lwm hom yog feem ntau yog lub fragmentation thiab tawg ntawm cov hlau sab hauv, hnav lossis corrosion hnyav rau hauv zos spalling. Yog li ntawd, daim ntawv thov ntawm laser cladding tshuab los ntxiv dag zog rau cov khoom nto ntawm qhov chaw tuaj yeem ua tau zoo rau kev pab cuam lub neej, thiab nyob rau hauv cov txheej txheem tu ncua sij hawm, cov khoom puas tuaj yeem kho tau los ntawm kev siv tshuab deg remanufacturing.
Turbine rotor kho
Rau cov pa roj thiab chav turbines, qhov chaw tsis ua haujlwm feem ntau tshwm sim hauv cov khoom kub-kawg xws li rotors, hniav thiab nozzles. Kev puas tsuaj tshwm sim ntawm cov hauv paus hniav ntawm cov hniav yog irreparable, thaum qhov kev puas tsuaj tshwm sim ntawm lub ntsej muag kawg lossis hauv paus hniav tuaj yeem rov qab siv tau tom qab kho. Tsis tas li ntawd, cov hniav siv los tsim cov txheej txheem feem ntau kim heev, thiab kev siv cov hniav rov qab siv dua yuav txo tau cov nqi hluav taws xob ntau.
Hauv kev lag luam tsheb tsim, txij li xyoo 1980, lub teb chaws xws li Tebchaws Europe, Tebchaws Meskas, Nyiv, Russia thiab Tuam Tshoj tau pib siv laser cladding los ntxiv dag zog rau tsheb qhov chaw. Los ntawm cov thev naus laus zis no, lub hom phiaj ntawm kev txuag cov khoom siv alloy kim thiab txo cov nqi tsim khoom tiav. Ib yam li ntawd, qhov tsis ua hauj lwm los ntawm kev hnav, corrosion thiab tiv taus qaug zog ntawm lub tsheb pwm hauv kev siv kuj tseem tuaj yeem ua kom rov zoo dua los ntawm cov cuab yeej no.
Nyob rau hauv luv luv, txawm hais tias nws yog qhov chaw ntxiv dag zog rau qhov chaw ua ntej kev pabcuam lossis kho qhov kev ua txhaum tom qab kev pabcuam, cov txheej txheem kev ua haujlwm feem ntau suav nrog qhov chaw quenching, deg carburizing lossis nitriding, thermal spraying, surfacing vuam thiab lwm yam. Nrog rau kev txhim kho txuas ntxiv thiab kev txhim kho ntawm kev ua cov thev naus laus zis, laser mobile remanufacturing thev naus laus zis (laser cladding) tau siv dav.
Qhov no laser remanufacturing tshuab tsis tau tsuas yog siv rau kev kho ntawm puas qhov chaw, tab sis kuj rau laser nto quenching, piv nrog rau cov tsoos tshav kub kev kho mob, laser quenching yog ib tug ceev cua sov thiab ceev txias ua technology, uas yuav tau txais ib tug hardened txheej ntawm zoo. nplej rau saum npoo. Tsis tas li ntawd, ua ke nrog high-end multi-axis tshuab cov cuab yeej los yog 6+2 robots, kev siv cov lasers kuj tuaj yeem kho peb-dimensional complex qhov chaw, tag nrho xav txog qhov yooj thiab siab heev ntawm laser remanufacturing technology.
