Hauv kev lag luam hnyav- qhov twg cov cuab yeej ua haujlwm nyob rau hauv cov xwm txheej hnyav xws li kev kub siab, cov khoom siv abrasive, thiab qhov chaw corrosive - lub sijhawm tsis tau npaj tseg thiab cov khoom siv tsis ua haujlwm tuaj yeem ua rau ntau lab hauv cov khoom lag luam poob. Cov kev kho ib txwm siv (piv txwv li, vuam, thermal txau) feem ntau poob qis ntawm kev xa tawm ntev - cov kev daws teeb meem, tab sisLaser Claddingtau tshwm sim ua kev ua si - hloov tshuab. Los ntawm kev tso nyiaj siab -kev ua tau zoo alloy coatings mus rau qhov hnav lossis puas, nws rov ua haujlwm, txhawb kev ua haujlwm ntev, thiab txo cov nqi kho. Hauv qab no, peb tshawb nrhiav yuav ua li cas laser cladding hais txog kev hnav thiab kev sib tw corrosion thoob plaws hauv kev lag luam hnyav tseem ceeb.
Laser Cladding rau Mining Machinery: Extending Service Life of Drill Bits and Crusher Parts
Mining machinery-los ntawm cov khoom siv tho mus rau cov khoom siv crusher- ntsib kev puas tsuaj tsis tu ncua los ntawm pob zeb, ore, thiab cov pob zeb hauv av. Ib qho kev xyaum me ntsis, piv txwv li, tuaj yeem hnav los ntawm 20% tom qab tsuas yog 10 teev ntawm kev ua haujlwm, yuav tsum tau hloov ntau zaus.Laser Claddingdaws qhov no los ntawm kev siv- cov khoom siv tiv taus (piv txwv li, tungsten carbide-cov hlau tsis muaj zog) rau qhov tseem ceeb ntawm cov khoom siv laum thiab lub puab tsaig crusher.
Lub precision ntawm laser cladding kom lub txheej adheres nruj nreem rau lub hauv paus cov ntaub ntawv, tsim ib daim ntawv cog lus 2-3 lub sij hawm muaj zog tshaj thermal spraying. Rau lub khob hliav qab crusher liners, cov txheej txheem no tsis yog tsuas yog kho qhov ntev ntawm lub ntsej muag, tab sis kuj ua rau lub ntsej muag hardness los ntawm 40-60%, ncua kev pab cuam lub neej los ntawm 2-3 zaug. Cov neeg ua haujlwm mining qhia txog 30% txo tus nqi kho thiab 25% tsawg dua qhov tsis tau npaj tseg tom qab siv laser{10}}cov khoom siv clad.
Kev lag luam roj thiab roj: Corrosion-Resistant Coatings for Downhole Tools
Downhole cov cuab yeej (piv txwv li, laum dab tshos, packers, li qub) nyob rau hauv cov roj thiab roj sector tiv thaiv kev sib tsoo ntawm kev kub siab (txog 15,000 psi), huab cua kub (dhau 300 degree), thiab cov kua dej corrosive (xws li dej ntsev, hydrogen sulfide). Corrosion- cuam tshuam txog kev ua tsis tiav ntawm cov cuab yeej no suav txog 40% ntawm cov nqi cuam tshuam zoo.
Laser Claddingmuab cov kev daws teeb meem: depositing corrosion{0}}cov alloys resistant (piv txwv li, Inconel 625, Hastelloy C-276) rau ntawm cov cuab yeej. Tsis zoo li cov txheej txheem ib txwm muaj (uas tuaj yeem tev lossis tawg thaum muaj kev ntxhov siab), laser-cov khaubncaws sab nraud povtseg ua ke nrog cov hlau hauv paus, tsim kom muaj kev sib khi tsis sib haum xeeb. Kev ntsuam xyuas teb qhia tau hais tias laser-clad downhole cov cuab yeej tswj kev ncaj ncees rau 5+ xyoo nyob rau hauv qhov hnyav offshore ib puag ncig-ob npaug lub neej ntawm cov tsis muaj coated los yog thermally sprayed lwm yam.
Automotive thiab Aerospace Solutions: Kho Cav Cheebtsam nrog Laser Cladding Technology
Hauv automotive thiab aerospace, cov khoom siv cav (piv txwv li, crankshafts, camshafts, turbine disks) xav kom nruj tolerances thiab siab qaug zog. Thaum cov khoom no tsim kev hnav, tawg, lossis cov khoom poob, kev hloov pauv feem ntau raug nqi (piv txwv li, ib qho aerospace turbine disk tuaj yeem raug nqi $ 50,000).
Laser Claddingenables meej, nqi- kho kom zoo: los ntawm melting alloy hmoov (muab raws li cov khoom siv hauv paus) mus rau qhov chaw puas, nws rov qab qhov qub qhov ntev thaum tswj cov khoom siv kho tshuab. Rau tsheb crankshafts, laser cladding kho cov ntawv xov xwm hnav nrog 0.01mm kam rau ua, thiab qhov rov qab ua tau raws li cov qauv kev ua haujlwm OEM. Nyob rau hauv aerospace, laser-clad turbine blades tau dhau 10,000+ teev ntawm cyclic fatigue tests-ua pov thawj lawv txoj kev ntseeg siab rau lub davhlau tseem ceeb.
Lub Hwj Chim Loj Loj: Txhim kho Turbine Blades tiv thaiv siab -Tsuas Hnav
Lub zog tsim hluav taws xob (fossil fuel, nuclear, geothermal) tso siab rau cov turbine blades uas ua haujlwm ntawm qhov kub siab tshaj 1,000 degree, ntsib oxidation, thermal qaug zog, thiab yaig. Cov hniav uas degrade ntxov ntxov tuaj yeem kaw tag nrho cov chaw tsim hluav taws xob, raug nqi $ 1-2 lab ib hnub hauv cov khoom ploj.
Laser Claddinghais txog qhov no los ntawm kev siv lub siab -kub- cov coatings resistant (xws li, MCrAlY alloys, ceramic composites) rau cov hniav nto. Cov txheej txheej no tsim cov txheej txheem tiv thaiv oxide uas tiv taus cua sov, txo qis hnav los ntawm 70% thiab txuas hniav lub neej los ntawm 4-5 xyoo. Rau cov thee- hluav taws xob hluav taws xob hluav taws xob, laser-clad turbine blades kuj tiv thaiv cov hmoov tshauv yaig-ib qho tsis ua haujlwm ua rau- txiav nqi tu txhua xyoo los ntawm $ 500,000+ ib chav.
