I. Txiav txim siab theem ntawm txoj kev loj hlob los ntawm txheej txheej corrosion morphology
1. Initial Corrosion: Nto oxidation, tseem thim rov qab
Cov yam ntxwv: tsaus me ntsis, dullness, los yog greyish me ntsis -dawb discoloration tshwm nyob rau ntawm qhov chaw ua hauj lwm, poob nws thawj metallic luster; nyob rau hauv lub teeb muaj zog, "dej zaj duab xis" los yog "sweat hlaws" yog pom.
Tactile Feedback: Ib me ntsis astringent hnov thaum zawv zawg ntiv tes; lub teeb daj - xim av ib puag ncig tom qab so nrog paj rwb ntaub.
Ceeb Toom: Nyob rau theem no, cov txheej txheem oxide tseem tsis tau tsim. Yog tias kho tsis pub dhau 48 teev, nws tuaj yeem rov qab ua tiav yam tsis muaj kev cuam tshuam qhov tseeb.
✅ Cov xwm txheej siv tau: Cov xim tsis sib xws ntawm lub rooj pom thaum lub sijhawm tshuaj xyuas niaj hnub lossis tsis siv roj sai tom qab lub tshuab kaw.
2. Intermediate Corrosion: Localized oxide txheej tsim, cuam tshuam haum
Cov yam ntxwv: Reddish-xim av lossis txiv kab ntxwv- cov pob daj tshwm nyob rau ntawm cov npoo ntawm qhov chaw thiab T- qhov chaw; hmoov xeb yog pom nyob rau hauv lub qhov; cov anti- spatter txheej tev tawm hauv zos, thiab cov xim hauv paus hloov.
Tactile Feedback: Tus pin positioning yog qhov nyuaj rau ntxig thiab yuav tsum tau maj mam tapping kom ncav cuag nws txoj hauj lwm zoo; tus txhuam taub hau nqa tawm xim liab - cov hmoov xim av thaum lub qhov ntxuav.
Kev Ceeb Toom: Qhov no tau cuam tshuam qhov sib nrug ntawm qhov siab ntev thiab rov ua dua qhov tseeb, uas tuaj yeem ua rau cov neeg hlau vuam txoj kev sib txawv los yog kho kom haum.
✅ Cov xwm txheej siv tau: siv ntau zaus, tu tsis tu ncua, lossis tsis muaj kev tiv thaiv zoo thaum lub caij los nag.
3. Corrosion hnyav: Sib sib zog nqus oxidation, kev pheej hmoo ntawm cov qauv qhia.
Cov yam ntxwv: Cov pob zeb xeb nthuav dav hauv thaj ua rau thaj, qhov chaw yog ntxhib, thiab cov pits hauv zos lossis cov ntawv pockmarks; Nyob rau hauv cov xwm txheej hnyav, cov txheej xeb tawm tawm, nthuav tawm cov substrate.
Tactile Cov Lus Qhia: Pom pom pom zoo los yog khawb zoo; nyuaj los ntxuav nrog tooj liab txhuam; siab tiv thaiv thaum lub sij hawm hluav taws xob lub qhov nqus tsev ntxhua khaub ncaws.
Risk Warning: May lead to flatness deviations (>0.1mm / m), xav tau lub tshuab kaw rau scraping lossis machining kho, cuam tshuam rau kev tsim khoom txuas ntxiv.
✅ Cov xwm txheej siv tau: Ntev- lub sijhawm tsis muaj kev saib xyuas, txuas txuas ntxiv yam tsis muaj kev tiv thaiv, lossis cov av noo ntau dhau.
II. Tsim kom muaj cov qauv txiav txim txiav txim raws li Quantitative Indicators
Txhawm rau zam qhov kev txiav txim siab tsis raug, nws raug nquahu kom xa mus rau cov theem hauv qab no kom muaj nuj nqis rau kev ntsuas:
1. Xeb Xeb Xeb: Yog tias tag nrho cheeb tsam xeb tshaj 5% ntawm qhov chaw ua haujlwm, nws raug suav tias yog qhov nruab nrab rau xeb thiab yuav tsum tau kho tam sim.
2. Qhov tob Corrosion Depth: Siv lub endoscope los yog ultrasonic thickness gauge, yog hais tias lub oxide txheej qhov tob yog ntau tshaj los yog sib npaug zos rau 0.1 hli, nws qhia tob corrosion.
3. Nto Roughness Hloov: Yog tias tus thawj Ra Tsawg dua lossis sib npaug ntawm 1.6μm, thiab qhov ntsuas tus nqi nce mus rau Ra Ntau dua lossis sib npaug rau 2.5μm, nws tuaj yeem suav tias yog xeb hnyav, cuam tshuam rau clamping stability.
4. Positioning and Fit Clearance: Measured with a mandrel and dial indicator, if the insertion resistance causes a displacement deviation >0.05mm, nws qhia tau hais tias lub qhov system yog tawm ntawm kev sib raug zoo.
Cov ntsuas no tuaj yeem suav nrog hauv daim ntawv tshuaj ntsuam xyuas txhua hnub kom ua tiav "cov ntaub ntawv-tsav" kev ntsuas xeb.
III. Ib puag ncig thiab kev siv-Cov Kev Ntsuas Txog Kev Ntsuas
Txawm hais tias tsis muaj qhov pom tseeb xeb ntawm qhov chaw, cov xwm txheej hauv qab no yuav tsum nce qib siab ntawm kev ceev faj:
1. Thaum lub caij los nag (Lub Rau Hli -Lub Xya Hli) hauv Wuxi, huab cua noo feem ntau tshaj 80%. Cam khwb cia hlau platforms (xws li HT300) yog qhov ua tau rau kev nqus dej. Nws raug nquahu kom ua qhov kev tshuaj ntsuam xyuas xeb tsawg kawg ib hlis ib zaug.
2. Yog tias cov khoom siv tsis tau siv ntau tshaj 7 hnub sib law liag thiab tsis tau coated nrog roj, txawm tias nws zoo li qub, nws yuav tsum raug suav hais tias yog qhov muaj peev xwm xeb.
3. Kev ua tsis tiav tam sim ntawm vuam slag thiab roj stains tom qab siv yuav ua rau cov seem absorbing noo noo thiab tsim ib qho chaw electrolyte, accelerating electrochemical corrosion.
🔍 Kev Ceeb Toom Tshwj Xeeb: Thaum muaj qhov sib txawv ntawm qhov kub thiab txias nruab nrab nruab hnub thiab hmo ntuj, "ua pa" ntawm lub platform yuav kos cov huab cua noo thiab condense, uas yog ib qho tseem ceeb ntawm kev zais xeb.
