Yam Khoom Yuav Tsum Thermal Spray Hmoov Muaj?

Ntxiv rau qhov ua tau raws li qhov yuav tsum tau ua ntawm cov txheej txheem, lubthermal spray hmoovNws tseem yuav tsum tau ua kom tau raws li qhov xav tau ntawm cov txheej txheem txau: nws tuaj yeem thauj mus rau hauv lub dav hlau nplaim dej ntws sib xws, ua haujlwm zoo thiab ruaj khov kom ntseeg tau tias muaj kev ruaj khov thiab tsis sib xws thermal spray txheej.Yog li ntawd, cov yam ntxwv ntawm cov hmoov xws li cov duab, particle loj thiab particle loj tis, bulk ntom, fluidity thiab nto zoo, yog ib qho tseem ceeb ntawm kev ua tau zoo ntawm thermal spray hmoov.

(1) Morphology ntawm hmoov hais

Feem ntau ntawm cov thermal spraying alloy hmoov cov ntaub ntawv yog npaj los ntawm txoj kev atomization, thiab cov hmoov particle morphology tsuas yog hais txog cov duab geometric thiab cov yam ntxwv ntawm cov hmoov av.Cov geometry tuaj yeem ntsuas tau los ntawm kev ntsuas qhov sib piv ntawm qhov luv axis mus rau qhov ntev axis (tus nqi txheeb cais) ntawm elliptical kheej kheej hais.Qhov siab dua qhov spheroidization degree, qhov zoo dua cov khoom-state fluidity ntawm hmoov.Txij li cov qib ntawm hmoov spheroidization tsis yog tsuas yog cuam tshuam nrog atomization hmoov milling txoj kev thiab atomization milling txheej txheem tsis, tab sis kuj rau cov tshuaj muaj pes tsawg leeg ntawm cov hmoov nws tus kheej.Yog li ntawd, spheroidization degree ntawm ntau hom hmoov kuj sib txawv, tab sis nws yuav tsum tau xyuas kom meej tias cov txheej txheem txau yuav du thiab txawm tias hmoov pub.

Qee zaum muaj qhov sib txawv ntawm qhov sib txawv hauv cov thermal spray hlau hmoov hmoov npaj los ntawm atomization, qee qhov nkag mus rau saum npoo, thiab qee qhov raug kaw hauv cov khoom.Yog tias cov txheej txheem txau tsis tsim nyog, nws yuav muaj kev cuam tshuam ncaj qha rau qhov zoo ntawm txheej.Txhawm rau soj ntsuam cov qhov no, feem ntau siv optical metallographic microscope.Deg nta hais txog xim nto, smoothness, thiab lwm yam.

(2) Particle loj ntawm hmoov

Kev xaiv ntawm hmoov particle loj thiab nws qhov ntau yog txiav txim siab los ntawm kev txau cov txheej txheem thiab cov txheej txheem txau cov txheej txheem tshwj xeeb.Txawm hais tias cov hmoov particle loj npaum li cas yog tib yam, qhov kev faib ua feem ntawm cov particle loj qib muaj pes tsawg leeg tsis tas yuav zoo ib yam.Piv txwv li: txawm hais tias cov hmoov me me yog nyob rau hauv thaj tsam ntawm 125μm ~ 50μm (-120mesh ~ + 320mesh), qhov kev faib ua feem ntawm cov hmoov ntawm peb qhov sib txawv particle loj qib ntawm 100μm ~ 125μm, 80μm ~ 100μm, 50μm ~ 80μm tsis zoo ib yam. .Cov hmoov particle loj ntau thiab nws cov qib particle loj muaj feem cuam tshuam ncaj qha rau cov txheej txheem zoo, hmoov bulk ntom thiab fluidity.

(3) Tej qhov ntom ntom ntawm hmoov

Powder bulk density yog hais txog qhov loj ntawm ib chav tsev ntim ntawm cov hmoov thaum nws xoob ntim.Txij li qhov ntau ntom ntom ntawm cov hmoov muaj feem xyuam rau cov qib spheroidization ntawm cov hmoov, qhov loj thiab qhov ntau ntawm cov qhov hauv cov hmoov hmoov, thiab muaj pes tsawg leeg ntawm cov hmoov particle loj, nws kuj cuam tshuam qhov zoo ntawm cov tshuaj tsuag txheej.

(4) Fluidity ntawm hmoov

Lub fluidity ntawm hmoov yog lub sij hawm yuav tsum tau rau ib tug npaum li cas ntawm cov hmoov kom ntws dawb do los ntawm ib tug qauv funnel nrog ib tug tshwj xeeb aperture.Nws feem ntau yog tus cwj pwm los ntawm lub sijhawm (s) xav tau rau 50g hmoov kom ntws los ntawm tus qauv funnel nrog txoj kab uas hla ntawm 2.5mm.Nws muaj qee yam cuam tshuam rau kev txau cov txheej txheem thiab txau cov txiaj ntsig.
