1. Ukwakhiwa Kwesendlalelo Sokudlula, Ukuthuthukisa Ukumelana Nokugqwala:
Ukumelana nokugqwala kwensimbi engagqwali kusekelwe ekwakhekeni kwesendlalelo se-passivation esihlanganisa i-chromium oxide (Cr2O3).Izici eziningana zingaholela ekulimaleni kongqimba lwe-passivation, okuhlanganisa ukungcola okungaphezulu, ukucindezeleka okuqinile okubangelwa ukucubungula ngomshini, nokwakhiwa kwezikali zensimbi ngesikhathi sokwelashwa kokushisa noma izinqubo zokushisela.Ukwengeza, ukuncipha kwe-chromium yendawo okubangelwa ukusabela okushisayo noma kwamakhemikhali kungenye into enomthelela ekulimaleni kongqimba lwe-passivation.Electrolytic polishingayilimazi ukwakheka kwe-matrix, ayinakho ukungcola namaphutha wendawo.Uma kuqhathaniswa nokucutshungulwa kwemishini, akuholeli ekuncipheni kwe-chromium ne-nickel;ngokuphambene nalokho, kungaholela ekunothisweni kancane kwe-chromium ne-nickel ngenxa yokuncibilika kwensimbi.Lezi zici zibeka isisekelo sokwakheka kongqimba lwe-passivation olungenasici.I-electrolytic polishing isetshenziswa ezimbonini zezokwelapha, zamakhemikhali, zokudla nezenuzi lapho kudingeka ukumelana nokugqwala okuphezulu.Kusukela electrolytic polishingkuyinqubo efinyelela ubushelelezi bobuso obuncane be-microscopic, ithuthukisa ukubukeka kwe-workpiece.Lokhu kwenza ukupholishwa kwe-electrolytic kulungele ukusetshenziswa emkhakheni wezokwelapha, njengezigxivizo zangaphakathi ezisetshenziswa ekuhlinzeni (isb., amapuleti amathambo, izikulufu), lapho kokubili ukumelana nokugqwala kanye nokuhambelana kwezinto eziphilayo kubalulekile.
2. Ukususwa kwama-Burrs nama-Edges
Ikhono lei-electrolytic polishingukususa ngokuphelele ama-burrs amahle ku-workpiece kuncike ekubunjweni nosayizi wama-burrs ngokwawo.Ama-burrs akhiwe ngokugaya kulula ukuwasusa.Kodwa-ke, kuma-burrs amakhulu anezimpande eziwugqinsi, inqubo yokuqothula ngaphambili ingase idingeke, ilandelwe ukukhishwa okongayo nokuphumelelayo ngokupholisha nge-electrolytic.Lokhu kulungele ikakhulukazi izingxenye zemishini ezintekenteke nezindawo okunzima ukufinyelela kuzo.Ngakho-ke, ukuchithwa kwemali sekube isicelo esibalulekileubuchwepheshe be-electrolytic polishing, ikakhulukazi izingxenye zemishini ezinembayo, kanye nezinto ezibonakalayo, zikagesi, nezakhi ze-elekthronikhi.
Isici esiyingqayizivele sokupholisha kwe-electrolytic yikhono layo lokwenza imiphetho yokusika ibe lula, ukuhlanganisa ukuchithwa nokupholishwa ukuze kuthuthukiswe kakhulu ukucija kwama-blades, ukunciphisa kakhulu amandla okugunda.Ngaphezu kokukhipha ama-burrs, ukupholisha nge-electrolytic kuphinde kuqede imifantu emincane nokungcola okushunyekiwe endaweni yokusebenza.Isusa insimbi engaphezulu ngaphandle kokuthikameze kakhulu indawo engaphezulu, ingethuli amandla ngaphezulu, iyenze indawo engenawo ukucindezeleka uma iqhathaniswa nezindawo ezingaphansi kwengcindezi eqinile noma ecindezelayo.Lokhu kuthuthukiswa kuthuthukisa ukumelana nokukhathala kwe-workpiece.
3. Ukuhlanzeka Okuthuthukisiwe, Ukunciphisa Ukungcola
Ukuhlanzeka kwendawo yokusebenza kuncike ezicini zokunamathela kwayo, futhi ukupholisha nge-electrolytic kunciphisa kakhulu ukunamathela kwezingqimba ezinamathelayo endaweni yayo.Embonini yenuzi, ukupholishwa kwe-electrolytic kusetshenziswa ukunciphisa ukunamathela kokungcola kwe-radioactive ezindaweni ezithintana naye ngesikhathi sokusebenza.Ngaphansi kwezimo ezifanayo, ukusetshenziswa kweipholishwe nge-electrolyticizindawo ezingaphezulu zinganciphisa ukungcoliswa ngesikhathi sokusebenza cishe ngo-90% uma kuqhathaniswa nezindawo ezicwebezeliswe i-asidi.Ukwengeza, ukupholisha nge-electrolytic kusetshenziselwa ukulawula izinto ezingavuthiwe kanye nokuthola ukuqhekeka, okwenza izimbangela zokulimala kwempahla eluhlaza kanye nokungafani kwesakhiwo kuma-alloys kucace ngemuva kokupholisha nge-electrolytic.
4. Ifanele Iziqephu Zokusebenza Ezimise Okungavamile
Electrolytic polishingiyasebenza nasezintweni zokusebenza ezinokwakheka okungavamile nezingafani.Iqinisekisa ukupholishwa okufanayo kwendawo yokusebenza, efaka kokubili ama-workpiece amancane namakhulu, futhi ivumela ngisho nokupholishwa kwemigodi eyinkimbinkimbi yangaphakathi.
