Ukuthembela kuphela ku-Ra (ubulukhuni obuphakathi nendawo) akwanele uma kuqhathaniswa i-electropolishing (EP) kanye ne-mechanical polishing (MP). Nakuba zombili izinqubo zinganciphisa i-Ra, zikhiqiza ubuqotho bomphezulu obuhlukene kakhulu, futhi ngenxa yalokho, ukusebenza okuhlukile kakhulu.
1. Umehluko Oyisisekelo Enqubweni
• Ukupholisha Okwenziwa Ngomshini (MP): Inqubo yokuhudula ethinta ubuso ngokusika, ukugcoba, nokunciphisa ungqimba. Isusa izinto ngokuguqulwa kwepulasitiki, ishiye ungqimba olusebenza kahle noluphambene.
• Ukupholisha nge-Electro (EP): Inqubo yamakhemikhali kagesi encibilikisa ngokukhetha iziqongo ezincane (amaphuzu aphezulu) kusuka ebusweni kuya ezigodini. Isusa i-ion yezinto ezibonakalayo nge-ion, ngaphandle kokucindezeleka komshini noma ukugcotshwa.
2. Lokho uRa angakutsheli kona
Ukupholisha Kwemishini Ye-Aspect
“Impilo” Yomphezulu Ishiya izinhlayiya ezihuzukayo ezifakiwe, insimbi egcotshwe, imifantu emincane, kanye nesendlalelo esisebenza ngokubanda kakhulu. Ikhiqiza indawo ehlanzekile, emsulwa ngamakhemikhali engenazo izinto ezingcolisayo ezifakiwe noma isendlalelo esigugile.
Ukumelana Nokugqwala Kungadala imifantu futhi kuphule ifilimu ye-oxide engasebenzisi i-passive oxide. I-grit ehlanganisiwe ingaqala umgodi. Isusa ungqimba oluphelelwe yi-chromium futhi inothise ubuso nge-chromium, yakha ifilimu eqinile, efanayo engasebenzisi i-passive.
Ukuhlanzeka Nokuhlanzeka Kunokuklwebheka okuqondiswe ngqo kanye nezigodi ezincane ezibamba amagciwane, uketshezi, kanye nezinhlayiya. Kuveza indawo engaqondisiwe, ebushelelezi, engenamifantu okulula kakhulu ukuyihlanza nokuyibulala amagciwane (okubalulekile kakhulu kwezokwelapha, ukudla, i-biotech).
Ukusebenza Kokukhathala Ukucindezeleka kokudonsa okusele kanye nokukhubazeka kobuso kunciphisa impilo yokukhathala. Kususa izinto eziphakamisa ukucindezeleka kanye nongqimba olulimele; kuvame ukuthuthukisa amandla okukhathala (ikakhulukazi kuma-alloy anamandla aphezulu).
Ama-Geometri Ayinkimbinkimbi Ayikwazi ukufinyelela ngempumelelo amabhodlela angaphakathi, imicu, amakhona, noma izingxenye eziyinkimbinkimbi. Iphatha ngokulinganayo zonke izindawo eziveziwe, kufaka phakathi izindawo okunzima ukuzifinyelela, kanye nokususa amabhodlela ngasikhathi sinye.
3. Izindinganiso Ezijwayelekile Ze-Ra - Ugibe
• Ukupholisha ngomshini kungafinyelela i-Ra ephansi kakhulu (isb., < 0.05 µm) – kodwa lokho kushelela kungase kube ngaphezulu, kufihle indawo engaphansi eyonakele.
• I-Electropolishing ivame ukunikeza amanani e-Ra aphakathi kuka-0.2–0.8 µm, okungase kubonakale “kuqinile” ngokwezibalo. Kodwa-ke, indawo ihlanzekile ngamakhemikhali, ayinayo ingcindezi, futhi imelana kakhulu nokugqwala.
Ezindinganisweni eziningi (isb., i-ASME‑BPE yemishini yezokwelapha), kudingeka i-Ra ethile, kodwa ukupholisha nge-electro kunconywa kakhulu ngoba kunikeza indawo engasebenzi ngempela, hhayi nje inombolo ephansi.
Ukuthatha Kokugcina
I-Ra iyinombolo nje – ilinganisa ukuphambuka kokuphakama, hhayi ikhwalithi yobuso.
Ukupholisha nge-electro kanye nokupholisha ngomshini kuyizinqubo ezihlukene ngokuphelele ezifeza izinjongo ezahlukene. Ukukhetha okulungile kuncike ezidingweni zokusebenza kwesicelo sakho, hhayi ekulandeleni i-Ra ephansi kakhulu.
