Ukuthembela kuphela kwi-Ra (uburhabaxa bomphezulu oqhelekileyo) akwanelanga xa kuthelekiswa i-electropolishing (EP) kunye ne-mechanical polishing (MP). Nangona zombini ezi nkqubo zinokunciphisa i-Ra, zivelisa ukuthembeka komphezulu okwahlukileyo kakhulu, kwaye ngenxa yoko, ukusebenza okusebenzayo okwahlukileyo kakhulu.
1. Umahluko oPhambili kwiNkqubo
• Ukupholisha ngoomatshini (MP): Inkqubo yokurhawuzelela ebonakalayo esika, itshise, kwaye iwusike umphezulu. Isusa izinto ngokuguqulwa kweplastiki, ishiye umaleko osebenza kakhulu nogqwethekileyo.
• Ukupholisha nge-electro (EP): Inkqubo ye-electrochemical enyibilikisa ngokukhetha iincopho ezincinci (amanqaku aphezulu) ukusuka kumphezulu ukuya ezantsi kwiintlambo. Isusa i-ion yezinto nge-ion, ngaphandle koxinzelelo loomatshini okanye ukutshiza.
2. Oko uRa angakuxeleli kona
Ukupholisha ngombane
Umphezulu “Impilo” Ishiya amasuntswana arhabaxa aqunyiweyo, isinyithi esitshisiweyo, imifantu emincinci, kunye nomaleko obanda kakhulu. Ivelisa umphezulu ococekileyo, ococekileyo ngokweekhemikhali ongenazo izinto ezingcolisayo eziqunyiweyo okanye umaleko okhubazekileyo.
Ukumelana Nokugqwala Kungadala imingxunya kwaye kwaphule ifilimu ye-oxide engasebenziyo. Umxube ohlanganisiweyo unokubangela ukuqhekeka. Isusa umaleko ophelelwe yi-chromium kwaye ityebise umphezulu nge-chromium, yenze ifilimu eqinileyo, efanayo engasebenziyo.
Ukucoceka kunye noCoceko Inomkrwelo obhekise kwicala kunye neentlambo ezincinci ezibamba iintsholongwane, ulwelo kunye neencindi. Ivelisa umphezulu ongabhekiseli kwicala, ogudileyo, ongenamiqolomba okulula kakhulu ukuwucoca nokuwucoca (okubalulekileyo kwimithi, ukutya, i-biotech).
Ukusebenza Kokudinwa Uxinzelelo lokuxinana olushiyekileyo kunye neziphene zomphezulu kunciphisa ubomi bokudinwa. Isusa izinto eziphakamisa uxinzelelo kunye nomaleko owonakeleyo; idla ngokuphucula amandla okudinwa (ingakumbi kwii-alloys ezinamandla aphezulu).
Iijometri ezintsonkothileyo Ayikwazi ukufikelela ngokufanelekileyo kwiimbobo zangaphakathi, imisonto, iikona, okanye iindawo ezintsonkothileyo. Iphatha ngokulinganayo zonke iindawo ezivezwe, kuquka iindawo ezinzima ukufikelela kuzo, kunye nokususa iimbumbulu ngaxeshanye.
3. Amaxabiso aqhelekileyo eRa – Umgibe
• Ukupholisha ngoomatshini kunokufikelela kwi-Ra ephantsi kakhulu (umz., < 0.05 µm) – kodwa loo nto ithambileyo isenokuba phezulu, ifihle umphezulu owonakeleyo.
• Ukucoca nge-electropolishing kudla ngokunika amaxabiso e-Ra aphakathi kwe-0.2–0.8 µm, anokubonakala “erhabaxa” ngokwenani. Nangona kunjalo, umphezulu ucocekile ngokweekhemikhali, awunaxinzelelo, kwaye umelana nokugqwala ngakumbi.
Kwimigangatho emininzi (umz., i-ASME‑BPE yezixhobo zamayeza), kufuneka i-Ra ethile, kodwa i-electropolishing iyacetyiswa kakhulu kuba inika umphezulu ongasebenziyo ngokwenene, kungekuphela nje inani eliphantsi.
Ukuthatha kokugqibela
URa linani nje – lilinganisa ukuphambuka kobude, hayi umgangatho womphezulu.
Ukupholisha nge-electropolishing kunye nokupholisha ngoomatshini ziinkqubo ezahlukeneyo ezisebenza ngeenjongo ezahlukeneyo. Ukhetho olufanelekileyo luxhomekeke kwiimfuno zokusebenza kwesicelo sakho, kungekhona ekulandeleni iRa ephantsi.
