Nto Roughness raws li Dual -Piv txwv Parameter hauv Titanium Cua sov Systems
Nto roughness yog ib qho tseem ceeb tab sis feem ntau underestimated parameter nyob rau hauv corrosion -resistant titanium cua sov raj. Nws cuam tshuam ncaj qha rau kev hloov hluav taws xob hloov hluav taws xob, cov dej ntws tus cwj pwm, thiab qhov chaw pib corrosion. Tsis zoo li qhov ntev geometric xws li txoj kab uas hla lossis phab ntsa tuab, qhov kev ntxhib los mos ntawm qhov chaw hloov pauv kev sib cuam tshuam ntawm cov raj thiab cov dej nyob ib puag ncig ntawm micro- nplai.
Titanium ib txwm tsim cov txheej txheem oxide ruaj khov uas muab kev tiv thaiv corrosion. Txawm li cas los xij, lub cev topography ntawm txheej txheej saum npoo no cuam tshuam li cas cov dej sib cuag cov khoom. Ib tug smoother nto feem ntau yuav txo tau nyob rau hauv lub zos turbulence thiab minimizes muaj peev xwm corrosion ntxiab, whereas roughness nruab nrab yuav txhim khu kev hloov tshav kub los ntawm kev ua kom zoo cheeb tsam.
Kev ua kom zoo tshaj plaws ntawm qhov chaw roughness yuav tsum ntsuas qhov kev ua tau zoo thermal ua haujlwm nrog ntev - cov tshuaj muaj zog.
Influence of Surface Roughness on Heat Transfer Rate
Thaum tshav kub kub hloov los ntawm lub titanium cua sov raj mus rau ib puag ncig nruab nrab tshwm sim feem ntau los ntawm convection. Qhov kev ua tau zoo ntawm cov txheej txheem no nyob ntawm qhov tuab ntawm thermal ciam txheej tsim nyob ze ntawm qhov chaw.
Nto roughness cuam tshuam cov ciam txheej thiab txhawb kev sib xyaw ua kua. Thaum cov microscopic protrusions txuas mus rau hauv cov kua dej, lawv tsim cov turbulence hauv ib cheeb tsam uas txhim khu kev sib hloov cua sov ntawm phab ntsa raj thiab cov kua. Cov txheej txheem no ua rau kom cov cua sov hloov coefficient thiab txhim kho thermal efficiency hauv cov tshuab ntws.
Txawm li cas los xij, qhov roughness ntau dhau tuaj yeem ua rau tsis muaj zog micro- thaj chaw uas cov dej ntws tsis sib xws. Cov cheeb tsam no tuaj yeem txo cov kev sib pauv cua sov zoo thiab sib sau cov impurities. Yog li ntawd, tswj roughness es tsis yog huab cua zoo nkauj feem ntau muab qhov zoo tshaj plaws thermal kev ua tau zoo.
Nyob rau hauv siab -flow systems, optimized deg zoo nkauj tuaj yeem txhim kho cua sov ceev yam tsis muaj zog ntxiv.
Kev sib raug zoo ntawm Surface Smoothness thiab Corrosion Resistance
Corrosion kuj nyob rau hauv titanium relies nyob rau hauv stability ntawm nws passive oxide txheej. Deg tsis xws luag xws li khawb, qhov, los yog roughness ntau dhau tuaj yeem ua raws li cov ntsiab lus pib rau hauv cheeb tsam corrosion nyob rau hauv cov tshuaj lom neeg ua phem.
Ib tug smoother nto txo tus naj npawb ntawm cov kab noj hniav microscopic qhov twg corrosive tshuaj yuav sau. Los ntawm kev txo qis qhov tsis sib xws, engineers txo qhov tshwm sim ntawm pitting corrosion thiab kev ntxhov siab concentration.
Hauv cov tshuaj chloride-nplua nuj los yog acidic ib puag ncig, qhov chaw ntxhib yuav ntxiab cov tshuaj electrolyte uas ua rau cov tshuaj tiv thaiv electrochemical. Polished titanium cua sov cov raj muaj kev txhim kho kev tiv thaiv vim tias cov dej sib cuag tseem zoo li qub thiab kev tiv thaiv oxide regeneration tshwm sim ntau zaus.
Cov kev kho deg tiav xws li cov tshuab polishing, electropolishing, lossis tshuaj kho tshuaj txhim kho corrosion kuj los ntawm refining nto qauv.
Kev tsim cov txheej txheem rau kev tswj qhov saum npoo roughness
Ntau cov txheej txheem kev lag luam tau siv los kho cov titanium raj nto cov yam ntxwv.
Mechanical polishing tshem tawm qhov tsis sib xws ntawm cov txheej txheem abrasive. Txoj kev no ua rau lub ntsej muag du haum rau cov ntawv thov uas xav tau kev tiv thaiv corrosion thiab kev tu cev.
Electropolishing siv cov txheej txheem electrochemical los xaiv kom yaj cov microscopic peaks ntawm cov hlau nto. Nws ua tau zoo smoothness thiab txhim kho oxide txheej uniformity. Cov txheej txheem no yog siv dav hauv tshuaj thiab tshuaj cua sov tshuab.
Txhaj tshuaj tua blasting los yog tswj roughening txoj kev txhob txwm tsim kom muaj kev ntxhib los mos los txhim kho cov cua sov hauv cov tshuab uas thermal efficiency yog qhov tseem ceeb tshaj qhov siab tshaj plaws.
Kev xaiv ntawm kev kho saum npoo yog nyob ntawm daim ntawv thov ib puag ncig thiab lub hom phiaj ua haujlwm.
Kev ua tau zoo sib piv ntawm qhov sib txawv ntawm qhov tiav
Cov lus hauv qab no qhia txog qhov sib txawv ntawm qhov ua tau zoo ntawm cov txheej txheem saum npoo.
| Surface condition | Thaum tshav kub kub kev ua haujlwm | Corrosion Resistance | Kev thov kom haum |
|---|---|---|---|
| Highly polished nto | Nruab nrab mus rau siab | Zoo heev | Muaj zog acid ib puag ncig, siab corrosion kuj |
| Nruab nrab ntxhib nto | Siab | Zoo | Flowing systems xav tau kev hloov pauv kom sov |
