Inconel 625 cov khoom lag luam tuaj yeem ua tiav li cas?
Cov txiaj ntsig ntawm qhov ua tau zoo tshaj plaws (Ra, qhov ntsuas qhov ntsuas qhov sib txawv) yog raws li hauv qab no:
Raws li -machined (Tig, Milling, Drilling)
Hom Ra: 1.6-6.3 μm
Nyob ntawm cov cuab yeej txiav, nrawm, pub, thiab cov khoom ua kom txias, ua tiav kom tsawg li 0.8 μm Ra tuaj yeem ua tiav hauv precision machining.
Av Ntog
Nrog nto sib tsoo los yog cylindrical sib tsoo, Inconel 625 tuaj yeem ua tiav:
Ntev: 0.2-1.6 m
Precision sib tsoo tuaj yeem tawm los 0.1-0.2 μm Ra rau qhov loj thiab qhov chaw tseem ceeb.
Polished nto
Polishing zoo: Ra 0.05-0.2 μm
Daim iav Polishing: Ra 0.01-0.05 μm
Nyob rau hauv siab - cov ntawv thov precision, xws li kho qhov muag lossis cov khoom siv kho mob, ua tiav mus txog Ra < 0.01 μm (ze - daim iav) tuaj yeem tau nrog cov txheej txheem polishing tshwj xeeb (xws li pob zeb diamond polishing).
Sandblasted / Tua Blasted nto
Qhov roughness nyob ntawm qhov blast media, siab, thiab nrug.
Hom Ra: 1.6-6.3 μm
Rau txheej adhesion, me ntsis rougher nto (piv txwv li, 3.2-12.5 μm Ra) feem ntau teev.
Electropolished nto
Electropolishing tuaj yeem txo qhov roughness thawj zaug los ntawm kev tshem cov peaks thiab smoothing hav.
Hom Ra tom qab electropolishing: 0.05-0.5 μm, nyob ntawm seb qhov chaw pib.
Nws yog tshwj xeeb tshaj yog zoo nyob rau hauv kev txhim kho nto tiav ntawm yav tas los av los yog polished qhov chaw thaum txhim kho corrosion kuj.
Hauv cov ntsiab lus, Inconel 625 cov khoom tuaj yeem ua tiav rau ntau yam ntawm qhov chaw roughness, los ntawm kev ua haujlwm tiav (piv txwv li, 1.6–6.3 μm Ra) kom zoo heev, iav -zoo li tiav (xws li,<0.05 μm Ra) through appropriate mechanical, chemical, or electrochemical treatments. The specific roughness achieved is usually determined by the application requirements, such as corrosion resistance, wear performance, fluid flow characteristics, or aesthetic appearance.
