Vim li cas thiaj li pits tshwm rau ntawm qhov chaw ntawm qhov chaw haujlwm?
Qhov laj thawj tseem ceeb tshaj plaws yog kev faib tawm cov hluav taws xob tsis txaus, thiab muaj ntau yam ua rau muaj qhov tsis txaus ntseeg ntawm kev faib tawm tam sim no, feem ntau yog hauv qab no:    

1. Qhov khoom ua kom yooj yim ua rau cov faib hluav taws xob tsis txaus sib luag. Txhim kho cov qauv txhim kho kom ua rau kev sib cuag ntawm cov khoom siv dag zog thiab haujlwm haujlwm kom sib npaug thiab muaj zog. Sim ua kom nce qhov chaw sib tiv tauj ntawm qhov kho kom raug thiab lub haujlwm thaum ua haujlwm kom paub meej tias lub fixture tsim nyog.   

2. Qhov tshwj xeeb nqus ntawm cov kua roj electrolytic polishing daws poob lossis tshaj tus nqi siab tshaj plaws. Yog tias nws ntau tshaj qhov xav tau ntawm lub ntiajteb txawj nqus ntau, qhov chaw ntawm lub workpiece yog nquag pitting. Lub ntiajteb txawj nqus tshwj xeeb tshaj plaws ntawm kev nqus ntshav yog 1.72.   

3. Qhov kub dhau dhau lawm, thiab qhov kub tuaj yeem ua rau electrolyte Kev Txhim Kho Hluav Taws Xob ua kom lub ntsej muag ci ntsa iab ntawm qhov chaw ua haujlwm, tab sis nws yooj yim los ua qhov tsis sib luag ntawm kev faib tawm tam sim no thiab ua rau pitting.    

4. Cov khoom ua haujlwm rov ua dua thiab cov khoom ua haujlwm yog qhov nquag pitting thaum lub tshuab nqus hluav taws xob thib ob. Txhawm rau kom tsis txhob pitting lub sijhawm thib ob, qhov hluav taws xob thib ob yuav tsum txo lub sijhawm thiab tam sim no kom haum.    

5. Cov pa roj kev khiav tawm tsis yog tus, cov kev khiav dim roj tsis yog du, feem ntau vim tias lub kaum sab xis ntawm lub taws ntawm lub workpiece tsis tsim nyog. Cov kev taw qhia ntawm orifice ntawm lub workpiece yuav tsum nce mus deb li deb tau. Kho qhov khoom siv rau lub kaum sab xis kom tsim nyog, kom cov pa roj uas tsim tawm thaum lub tshuab hluav taws xob polishing ntawm lub workpiece tau yooj yim tawm. 

6. Lub sijhawm hluav taws xob lub sijhawm ntev dhau. Kev ntsuas hluav taws xob yog cov txheej txheem theem me me. Thaum lub ntsej muag ntawm lub workpiece mus txog microscopic lub teeb ci thiab qib, qhov saum npoo ntawm qhov yuav nres oxidizing, thiab yog hais tias qhov electrolysis txuas ntxiv, nws yuav ua rau dhau-corrosion thiab pitting.   

7. Overcurrent Thaum cov seem ntawm electrolytically polished, yog hais tias tam sim no dhau los ntawm qhov chaw loj dhau, lub xeev yaj ntawm lub nplaim ntawm ib feem yog ntau dua li lub xeev oxidation ntawm qhov chaw ntawm ib feem, ces saum npoo ntawm ib feem yuav yuav dhau kev corroded, thiab cov ntsiab lus corrosion yuav tau tsim
