Cov tub ntxhais ntawm laser hardening thiab saum npoo℃rau cov ntaub ntawv hlau
Hauv kev lag luam kev tsim khoom, lub hardness thiab lub zog ntawm cov khoom siv hlau ncaj qha txiav txim siab txog kev ua haujlwm thiab kev nyab xeeb ntawm cov khoom. Laser hardening technology, nrog nws cov txiaj ntsig ntawm kev ua tau zoo thiab precision, tau dhau los ua qhov tseem ceeb los txhim kho kev ua haujlwm ntawm cov ntaub ntawv hlau. Raws li ib tug tub ntxhais ua ntej-}}}}}}}}}}}}}}}}} pret pret pret pretrment directly cuam tshuam ncaj qha rau kev ua haujlwm kom haum ntawm laser zog thiab qhov kawg hardening zoo. Kab lus no yuav tawg cov ntsiab lus tseem ceeb ib puag ncig ntawm cov ntaub ntawv hardreatment, qhov tseem ceeb ntawm kev tsim kho saum npoo av, thiab kev tsim kho kev lag luam, muab cov ntaub ntawv siv rau cov kws kho mob.
Cov Tswv Cuab Ua Haujlwm tseem ceeb ntawm Laser hardening rau cov ntaub ntawv hlau
Cov tub ntxhais ua haujlwm ntawm Laser Hardening rau cov khoom lag luam hlau los ntawm cov hlau lead ntawm lub thermal kev ntxhov siab thiab lim ntawm workpiece lub txheej txheem sab npoo. Hloov chaw, nws tso siab rau siab- lub zog {} Cov txheej txheem cua sov ua kom muaj kev ntxhov siab saum hlau ua kom muaj zog, thiab tsis muaj zog, thiab lub zog loj heev. Txij li thaum lub laser tsis ncaj qha cuam tshuam ncaj qha txheej txheej kev ntxhov siab, uas tseem yog qhov pib ua ntej rau kev pom zoo ua ntej rau kev lees paub cov nyhuv tawv.
Qhov tseem ceeb ntawm kev tshwm sim nto ua ntej Laser hardening
Tom qab kev ua txhua yam, cov nplaim hluav taws xob feem ntau muaj cov khoom siv hlau tsis tshua muaj qhov ua rau muaj kev cuam tshuam li 80-90% rau cov lasers. Ib qho nyiaj ntau ntawm laser hluav taws xob tau ploj vim yog xav txog, cuam tshuam ncaj qha cuam tshuam rau kev nqus hluav taws xob ntawm lub zog hlau. Qhov no ntxiv rau cov neeg txom nyem hnyav hnyav thiab muaj teeb meem ntawm kev tsis sib haum xeeb hauv zos. Yog li ntawd, lub hom phiaj tseem ceeb ntawm cov txheej txheem saum npoo
Cov Txheej Txheem Tshaj Tawm Sab Nraud Sab Nraud thiab cov ntsiab lus tseem ceeb rau kev ua kom nruj
Cov txheej txheem saum npoo deg sab hauv cov qauv yog cov xim txau txoj kev ua kom haum thiab haum rau cov xwm txheej sib txawv:
•Txoj kev txau cov xim: Nws muaj cov txheej txheem yooj yim thiab ceev ceev, xav tau tsis muaj kev kho mob lossis kev kho kom sov ntxiv ntawm cov haujlwm ua haujlwm. Nws tuaj yeem siv rau cov pawg ntau lawm thiab tseem rau phau txhuam hniav (haum rau kev ua si ua / sim), tsis tas yuav muaj kev xav tau kom tiav cov cuab yeej ua tiav. Cov kauj ruam ua haujlwm: Tom qab ntxuav cov hlau ua haujlwm nrog dej, tso nws hauv dav hlau cua lossis ntshav rau cua sov thiab cua sov; Tom qab ntawd tsuag cov txheej saum npoo thiab qhuav nws los ua cov txheej tuab. Lub txheej tuab yuav tsum tau tswj ntawm 50 {{4 4}} 100 microns (ntau dhau heev yuav ua rau "hlawv-los"). Feem ntau cov txheej txheem yuav nce cov nqi sib haum laser kom dhau 80-98%, ntsib cov cai ntawm laser quenching.
•Phosphating Txuj Ci: Nws yog feem ntau yog cov txheej txheem kawg hauv kev ua haujlwm thiab tuaj yeem txuas ncaj qha rau laser tawv. Raws li qhov ntsuas kub, nws tau muab faib ua lub siab- kub phospating (36 {10} {- kub phospating (nyob ib ncig ntawm 25 degree). Siab - kub thiab nruab nrab-kub phosphalls yog qhov zoo tshaj plaws (cov yeeb yaj kiab phospects muaj tus nqi siab dua). Lub thickness ntawm phosphaating zaj duab xis yuav tsum tsawg dua 20 microns kom tsis txhob "hlawv-los" cuam tshuam rau kev ua tau zoo. Ib qho ntxiv, cov txheej txheem rougening thiab oxidation siv tau siv tau, ntawm cov qauv oxidation thiab txau txoj kev muaj cov thev naus laus zis thiab tuaj yeem xaiv raws li xav tau.
Kev lag luam kev txhim kho tiam ntawm laser hardening thiab pretreatment rau cov ntaub ntawv hlau
Nrog cov kev txhim kho ntawm cov ntaub ntawv muaj kev lag luam, cov ntaub ntawv tshiab xws li nano - nplai oxides, cermets, thiab cov txheej txheem hlau yog nthuav tawm tas li. Cov ntaub ntawv no tso rau cov kev yuav tsum tau ua rau kev yoog raws li kev hloov pauv ntawm cov kev ua kom zoo thiab ua kom pom tias cov ntaub ntawv tshiab tuaj yeem nqus tau lub zog tshiab. Nyob rau tib lub sijhawm, kev hloov thev naus laus zis ntawm cov khoom siv laser laser txuas ntxiv mus txhawb nqa cov khoom siv tshuab hluav taws xob ntxiv rau cov kev siv tshuab loj ntawm laser hay cov thev naus laus zis.
Cov Cheebtsam ntawm Laser Cladding System
Cov ntsiab lus tseem ceeb ntawm laser hardening thiab saum npoo degrerveatment rau cov ntaub ntawv hlau
Hauv cov ntsiab lus, cov tub ntxhais ntawm laser hardening rau cov khoom lag luam hlau yog txhawm rau txhim kho qhov kev xav zoo ntawm cov hlau thiab ua kom muaj cov nyhuv tawv. Raws li cov txheej txheem tseem ceeb pretreatment txoj kev, cov xim txau cov qauv thiab cov qauv tshuaj phospects thiab kub kom ntseeg tau tias cov qauv kev ua kom haum kev raws li Laser. Nyob rau yav tom ntej, nrog rau daim ntawv thov ntawm cov ntaub ntawv tshiab thiab kev txhim kho tshuab yuav tsum tau yoog raws kev txhim kho kev txhim kho kom zoo dua qub hauv kev lag luam ua lag luam.
