Siab - Ceev Laser Cladding Khoom: Kev tsom xam ntawm cov tseem ceeb soj ntsuam cov khaubncaws sab nraud povtseg
Nyob rau hauv daim teb kev lag luam thiab sib xyaw kho, siab {}} ceev laser cladding cov khoom siv tau ua haujlwm rau txhim kho thiab siab {1} pre} precision txheej npaj. Qhov zoo tshaj ntawm cov cladding txheej txiav txim siab cov kev pabcuam lub neej ntawm kev soj ntsuam kev soj ntsuam {3 los ntawm ntom ntom nti thiab cov neeg kho tshuab kom muaj kev sib xyaw ruaj khov thiab qhov chaw muaj mob. Txawm hais tias cov txheej txheem no tau raws cov qauv yog sib cuam tshuam nrog cov txheej txheem txheej txheem ntawm cov khoom siv laser cladding. Kab lus no tsom rau cov tseem ceeb tshuaj xyuas cov khoom tsis txaus ntseeg nrog siab cov ntsiab lus siab, piav lawv cov ntsiab lus ceev, thiab cov cuab yeej hloov kho rau cov ntawv thov kev lag luam.
Porosity: Cov Qauv Tseem Ceeb Ntawm Cladding Txheej Nthuav Qwj Rau Laser Cladding Cov Khoom
Porosity yog qhov ntsuas ntsuas ntsuas rau ntsuas qhov ceev ntawm cov txheej txheem npaj tau los ntawm high {}} ceev laser cladding cov khoom siv. Nws yog hais txog feem pua ntawm cov ntim ntawm cov txheej cladding rau tag nrho cov chaw ntim khoom (xws li sib tw tshuaj ntsuam, x}} pay qhov kom pom tseeb). Cov khoom siv hluav taws xob ntau dhau ntawm cov khoom siv tsis sib xws, thiab cov khoom siv tsis sib xws Yog tias lub zog tsim hluav taws xob nter ntawm cov khoom siv tsis raug cai, lub pas dej Molten ua haujlwm nrawm heev, tawm tsis muaj sijhawm khiav tawm thiab yog li ua qhov hws kaw. Tsis tas li ntawd, cov ntsiab lus noo noo thiab particle xeev ntawm cov hlau hmoov yoog raws cov khoom siv kuj tsis ncaj ncees los ntawm cov khoom siv Conveying. Yog li ntawd, nws yog qhov tsim nyog los xaiv cov hmoov xaiv hmoov thiab hmoov noj kom tsis muaj ntau nyob rau hauv raws li cov khoom siv cov yam ntxwv.
Hardness: Cov Kho Tshuab Cov Tshuab Laser Cladding Nyob rau hauv Cov Cwj Pwm Cua Txias
Hardness, feem ntau tau hais tawm hauv Rockwell Hardness (HRC), yog lub cim tseem ceeb rau kev ntsuam xyuas cov hnav tsis kam ntawm txheej cladding. Nws cov ua tau zoo nce nta los ntawm "Cov nyhuv txias ceev" ntawm high - ceev laser cladding cov khoom siv. Cov cuab yeej siv xws li lub zog laser kom sov lub pas dej molten ntawm ib txheej txheem cua txias, thaum muaj cov txheej txheem ntawm cov av nplaum kom zoo dua li 30 feeb degree. Qhov no inhibits qoob loo loj hlob thiab ua rau lattice distortion, thaum kawg ua rau muaj kev nyuaj siab. Piv txwv li, hauv kev siv cov ntawv thov, thaum lub lt series siab siab high { Cov xeeb ceem no ua rau cov khoom siv tau siv rau kev ua cov khoom siv xws li cov khoom siv mining, thiab cov kev tsim kho kom zoo ntawm kev tswj hwm ntawm laser zog thiab tus nqi cua txias.
Bonding zog: Cov kev ua kom muaj kev sib koom ua ke ntawm cov sib txuas ntawm cov khoom siv laser cladding
Tsevneeg sib txig muaj zog, ntsuas hauv MegaceSlascals (MPa), txiav txim seb puas muaj kev nyab xeeb rau cov txheej txheem kev nyab xeeb ntawm high {}} ceev laser cladding cov khoom siv. {-} Ua zoo Laser Cladding Khoom yuav ua tiav "metallurgical kev hloov kho ntawm sab nraud, thaum lub siab} ceev yooj yim converted hmoov yog melted hmoov kiag li. Atomic diffusion tshwm sim nyob rau hauv lub pas dej molten los ua ib daim ntawv cog lus ruaj khov, uas txawv ntawm cov neeg kho cua sib txig sib txig sib txig. Piv txwv li, qhov siab - Ceev cov khoom siv Guosheng tuaj yeem ua haujlwm hnyav ntawm cov neeg ua haujlwm hnyav xws li Shield tshuab txiav thiab lub cav thaiv. Thaum kuaj xyuas, cov qauv npaj npaj los ntawm cov cuab yeej yuav tsum tau ntsuas nrog kev pab ntawm lub ntsuas phoo ntawm lub zog tensile kom ntseeg tau tias lub zog sib zog ua tau cov qauv.
Dilution Feem pua: Qhov tseem ceeb parameter rau laser cladding cov khoom siv los tswj cov cladding txheej
Dilution tus nqi yog hais txog kev faib ua feem ntawm melted substrate hlau nyob rau hauv cov txheej txheem kev ua tau zoo ntawm cov kev ua tau zoo, thaum muaj zog ntau dhau lawm. High - Ceev laser cladding cov khoom siv los ntawm peb cov khoom noj khoom haus cov khoom siv tuaj yeem txo tus ncaj qha laser cua sov ntawm cov substrate; Txhim kho cov laser fais fab density (qhov sib piv ntawm lub zog kom pom qhov loj me) tiv thaiv ntau yam melting ntawm substrate; thiab yoog raws li Cladfering luv luv luv luv luv luv luv ntawm lub sijhawm nruab nrab ntawm lub laser thiab substrate. Tam sim no, kev ua cov cuab yeej muaj xws li cov khoom lag luam Guosheng tuaj yeem tswj hwm tus nqi kwv yees li 1%, ntau dua li ntawm cov khoom lag luam laser cladding. Cov qib no tuaj yeem ua kom ntau dua ntawm kev tsim nyog ntawm cov hmoov uas tsim tau ntawm cov hmoov av, kom haum rau cov duab ua haujlwm zoo xws li pwm thiab tshuab hluav taws xob.
Logic ntawm Laser Khoom Cladak parameter debugging thiab zoo ua kev cai
Hauv cov ntsiab lus, kev ua tau zoo ntawm high - ceev laser cladding cov khoom siv nrog cov cladding txheej ua tsis xws li lub hom phiaj. Hauv kev siv cov kev siv, nws yog qhov tsim nyog los qhia txog kev ua haujlwm (xws li hnav tsis kam thiab siab} cov hmoov hlau ua haujlwm raws li cov khoom siv hlau; Ua kom zoo Porosity, Hardness, thiab cov dilution tus nqi xws li cov hmoov pub ceev, thiab cladding ceev ntawm cov khoom; Thiab thaum kawg xyuas kom meej tias txhua qhov kev tshuaj xyuas cov qauv kev lag luam kom tau raws li cov kev siv kev siv ntawm cov teb sib txawv xws li tsuas, aerospace, thiab machinery. Nyob rau hauv lub neej yav tom ntej, nrog kev txhim kho cov ntse laser cladding, parameter debugging yuav dhau los ua kev txhim kho ntawm cladding txheej zoo thiab muaj cov ntawv thov kev siv tau.
