Laser cladding kho tshuab rau cov pa luam yeeb lub tshuab ntsuas hluav taws xob disking thiab tuaj
Lub turbine disk thiab turbine hniav ntawm cov pa taws tshuab yog cov khoom siv tsis yooj yim thaum cov cuab yeej ua haujlwm. Qhov tsis xws luag xws li hnav, tawg, thiab corrosion ntawm cov khoom siv no yuav cuam tshuam ncaj qha rau cov pa luam yeeb cov pa luam yeeb ua haujlwm thiab lub neej pabcuam. Raws li lub siab - precision kho txoj kev siv, ua tiav cov nyhuv ntawm "rov qab los li - kev mob tshiab". Kab lus no yuav nthuav qhia cov ntsiab lus tseem ceeb ntawm laser cladding kho rau cov pa luam yeeb los kho kom zoo nkauj thiab los ntawm pretreatment kho tshuab thiab muab cov ntaub ntawv siv rau kev tsim nyog.
Cov ntsiab lus tseem ceeb ntawm laser cladding kho rau cov pa luam yeeb lub cav tshuab luam yeeb
Cov tub ntxhais lub hom phiaj ntawm kev kho lub zog disk yog "thawj zaug kho tsis xws luag thiab tom qab ntawd txhim kho kev ua haujlwm". Ua ntej, kev ua kom pom tseeb tau ua: rau cov zeem muag pom tseeb ntawm cov disk thiab nws cov kev sib tsoo, sib tsoo yog ua kom cov tiaj nrag hauv qab; Rau txhua txoj kev corrosion thiab kab nrib pleb, vuam siv rau kev kho kom huv kom tsis txhob muaj kev puas tsuaj theem ob. Tom qab pretreatiction, laser cladding Technology yog saws rau clad alloy hmoov (nrog kev ua tau zoo ib yam nrog cov khoom siv hauv paus) ntawm lub turbine disk nto. This process requires no primer or preheating and can directly form a high-hardness alloy layer, which not only ensures the compatibility between the cladding layer and the base material but also significantly improves the wear resistance and corrosion resistance of the turbine disk.
Pretricatment thiab kev paub cov txheej txheem tau txais rau cov hniav turbine
Kev npaj ua ntej rau cov hniav kho kom muaj ob txoj haujlwm tseem ceeb. Thawj qhov yog cov txheej txheem ua ntej, uas muaj peb kauj ruam ntawm kev tu: Ua ntej, roj thiab xeb tawm ntawm qhov chaw ua haujlwm kom tiav; Tom qab ntawd, sandblasting tu yog siv los tshem tawm cov txheej oxide thiab impurities, txhim kho txoj kev sib txuas ntawm cov txheej txheem txuas ntxiv; Thaum kawg, kev ntxuav huv tshwj xeeb yog ua rau thaj chaw Cladding, thiab thaj chaw nrog pom tseeb yog leveled kom muaj kev huv thiab tiaj tus hauv av rau cladding. Qhov thib ob yog qhov pom tau ua ke: Pom kev sib txuas ua ke pom tseeb hnav thiab cov kab nrib pleb, thiab kuaj cov kev ntsuas zais cia xws li microcacks thiab porosity nyob sab hauv. Nyob rau tib lub sijhawm, qhov loj me, thiab hom kev tsis xws luag nyob rau hauv thaj chaw kho tau sau cia kom ntseeg tau tias tsis muaj qhov muag tsis pom kev.
Laser Cladding thiab Post - Ua rau turbine hniav
Laser Cladding yog tus tseem ceeb txuas hauv cov khoom sib xyaw, xav tau kev tsim hluav taws xob nce ntxiv: Thaum kho tau cov cua sov {}}} kub thaj tsam thiab tiv thaiv tawg; Thaum txuas ntxiv sab saum toj ntawm cov yas hnav, lub zog ua kom muaj zog, ua kom pom kev nrawm, thiab kev ntsuas nrawm yog tswj kom muaj kev tawg ntawm cov txheej cladding. Yog tias pulsed yag laser tsis muaj, co cov cladding yog tseem tuaj yeem ua tiav tib cov nyhuv. Tom qab cladding, cov hniav yuav tsum tau hauv av, polished, thiab txiav kom ntseeg tau tias lawv cov qauv tsim qauv, zam kev tsis zoo ntawm aerodynamic kev ua tau zoo.
Kev Soj Ntsuam Zoo thiab Kev Kho Kom Zoo rau Turbine Rho
Tom qab cov hniav hniav kho, nruj tswj hwm yog qhov yuav tsum tau ua kom tau kev kuaj xyuas (xws li kev kuaj xyuas txheej txheem Tom qab dhau kev soj ntsuam zoo, kev ua tiav kev kho theem pib, qhov twg cov txheej txheej saum npoo av tau thov rau cov hniav. Siab - kub thiab corrosion {{3} {{{} {{4 4} {{4 4} {{4 4} {{} Lub cev muaj kev pabcuam tom qab kho.
Cov Cheebtsam ntawm Laser Cladding System
Zuag qhia tag nrho ntawm laser cladding Kho
Los ntawm cov txheej txheem phiaj xwm ntawm "kho kom haum + rau cov pa hluav taws xob ua tau zoo thiab cov txheej txheem ua haujlwm zoo nkauj, ua tiav lub hom phiaj ntawm" rov qab los li- mob tshiab ". Qhov thev naus laus zis no tsuas yog siv cov teeb meem ntawm cov nqi ntawm cov neeg siv hluav taws xob, muab kev txhawb nqa kev ua haujlwm ntev ntawm cov pa luam yeeb.
