Xyoo tsis ntev los no, nyob rau hauv kev taw qhia ntawm lub teb chaws kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig txoj cai thiab kev hloov pauv kev lag luam thiab kev hloov pauv tshiab, cov tsoos chromium plating thev naus laus zis tau tshawb fawb txuas ntxiv thiab tsim kho, thiab kev tiv thaiv ib puag ncig qib ntawm cov txheej txheem kev tsim kho tau muaj txiaj ntsig zoo kom paub txog qhov ntse. raug thiab ntsuab raug. Raws li kev tshaj lij ib puag ncig tiv thaiv kev tsim kho thev naus laus zis, ultra-high speed laser cladding thev naus laus zis tawm raws li lub sijhawm xav tau, uas coj txoj kev tshiab tawm.
Rau qhov zoo ntawm ultra-siab ceev laser cladding: 1
Kev ua haujlwm siab: hauv cov tsoos laser cladding cov txheej txheem, cov kab cladding kab nrawm feem ntau yog 600-1000mm / min, cov cladding efficiency feem ntau yog 0.15m2 / h, thaum lub siab laser laser cladding kab ceev tuaj yeem ncav cuag 20-150m / min, lub cladding efficiency tuaj yeem ncav cuag 0.5-2m2 / h, thiab kev ua haujlwm ntawm kev ua haujlwm tag nrho yog 3-5 zaug ntawm qhov tseeb ntawm kev sib dhos.
Tsawg tus nqi machining: cov machining cov kauj ruam hauv qab no ntawm cov txheej npaj los ntawm cov tsoos laser cladding suav ntxhib tig thiab zoo sib tsoo, thaum txheej txheej npaj los ntawm kev kub ceev laser cladding muaj tsawg dua machining kev tso cai thiab ci nto, thiab tsuas yog xav tau zoo sib tsoo, uas zoo heev txuag tus nqi (khoom siv nqi, machining cov nqi thiab lub sij hawm tus nqi) rau ib yam twg. Cov txheej txheej yog pob thiab du, thiab lub thickness ntawm ib txheej tuaj yeem ncav 0.15 hli los ntawm kev kub ceev laser cladding, thiab txheej txheej tuab tuaj yeem hloov kho los ntawm 0.15 mus rau 0.5 hli (txheej tib) los ntawm kev kho cov txheej txheem. Cov xim txheej ntau yog feem ntau cuam tshuam rau cov txheej txheem cov txheej txheem xws li cladding ceev thiab hmoov noj zaub mov tus nqi.
Cov tswv yim me me thaum tshav kub kub: kev kub ceev laser cladding muaj cov tswv yim me me hauv tshav kub thiab kev hloov kho cua sov, uas tuaj yeem siv los ua txheej txheem nyias-phab ntsa thiab qhov loj me me. Hauv cov txheej txheem tsoos laser cladding, feem ntau ntawm laser lub zog yog tsom rau ntawm daim nyias nyias thiab txheej txheej. Lub sijhawm no, vim muaj lub thermal nthuav tsis sib xws thiab lwm yam khoom siv ntawm lub cev, nws yooj yim los ua kom muaj kev ntxhov siab nyob rau hauv txheej xim. Rau qee txheej txheej nrog lub siab tawv, nws yog qhov yooj yim kom tawg hauv txheej txheem. Hauv kev ua tiav ntawm ultra-high speed laser cladding, 80% ntawm laser lub zog ua rau ntawm cov hmoov, yog li cov txheej txheem deformation ntawm cov substrate muaj tsawg dua cov kev nyuaj siab, thiab txheej yuav tsis tawg yooj yim.
Metallurgical tsevneeg: ultra siab ceev laser cladding tuaj yeem paub cov xim hlau ua kom sib xyaw ntawm kev ua lej thiab alloy txheej. Cov txiaj ntsig ntawm kev xeem tawg thiab 600 tuj xovxwm qhia pom tias tsis muaj qeeb thiab loj ntxiv.
Kev kub siab sib piv: ntau ntawm cov khoom hauv cov txheej hauv qab diffuse upward, uas cuam tshuam tag nrho cov kev ua tau zoo ntawm cov txheej (hardness, corrosion resistance) ib txwm muaj teeb meem loj ntawm laser cladding. Thaum cov txheej txheem hardness siab tau npaj rau saum npoo steel, nws yooj yim los txo cov txheej hardness. Txawm li cas los xij, cov teeb meem no yuav tsis tshwm sim hauv kev kub ceev laser cladding, vim hais tias lub dilution ratio ntawm high-speed laser cladding yog qis dua li cov tsoos cladding, ntau lub zog siv nyob rau hauv cov hmoov, thiab cov khoom hauv substrate tsis muaj txaus thermal tsav quab yuam kom diffuse rau hauv txheej, yog li nws yog dav siv Lub zog laser ntom ntom yog qhov siab, uas tuaj yeem siv rau cladding siab melting point hmoov hmoov cov ntaub ntawv, thiab tseem tuaj yeem paub txog qhov ua kom zoo dua ntawm cov tooj liab, txhuas, titanium thiab lwm yam khoom siv hlau tsis muaj hlau.
Laser cladding tsuas yog siv nyob rau sab saum toj kev hloov kho ntawm cov khoom siv (cov menyuam thiab cov iav), kev kho saum npoo ntawm cov khoom (rotor thiab iav) thiab cov qauv kev tsim khoom. Los ntawm kev txhim kho kev ua haujlwm tsis tu ncua, thev naus laus zis tuaj yeem siv dav hauv cov thee, metallurgy, ntug dej hiav txwv platform, papermaking, cov khoom siv pej xeem, tsheb, nkoj, roj, kev lag luam huab cua.
