1. Ihame ry'ingenzi: Gukoresha Electroplating mu buryo bw'inyuma
Electropolishing ni ugushonga kw'icyuma mu bwogero bwa electrolyte hakoreshejwe electrochemical kugira ngo bikureho ibikoresho byo hejuru, bigabanye ubukana, kandi bikorwe neza kandi bidakoresha amashanyarazi.
Tekereza kuri byo nk'ukobitandukanye no gushushanya hakoreshejwe amashanyarazi:
● Gukoresha amashanyarazi: Umurimo ni cathode ($-$-$) → Iyoni z'icyuma ziva ku isahani y'umuti zikajya hejuru.
● Gutunganya amashanyarazi: Igikorwa ni anode ($+$) → Atome z'icyuma zirakurwa ku buso zikajya mu gisubizo.
2. Urufunguzo rwo Gutunganya: Urusobe rw'Umupaka Ufite Ingufu
Iyo gushonga kwa anodike byakuraho icyuma gusa, byaca ubuso bwacyo. Bigenda bite kugira ngo bikosorwe? Igisubizo kiri mu gice cy'umupaka kimeze nk'uruziga, igitekerezo cy'ingenzi mu nyigisho ya electropolishing.
● Imiterere: Uko iyoni z'icyuma zishonga zivuye kuri anode, zirundanya mu gice gito cya electrolyte kiri hafi y'ubuso bw'aho imikorere ibera.
● Ingano y'ibyiyumviro: Uru rwego rurushaho kuba rwinshi cyane hamwe na iyoni z'icyuma, bikongera ubukana bwarwo no kudakoresha amashanyarazi.
● Uburyo bwo kugenzura gukwirakwiza kw'ibinyabutabire: Igipimo cyo gushonga ntikigengwa n'imbaraga z'amashanyarazi cyangwa uburyo ibintu bigenda bihinduka, ahubwo kigengwa n'uburyo izi ion z'icyuma zishobora gukwirakwira zivuye ku buso zijya muri electrolyte nyinshi.
3. Ikibaya cy'amazi kidahinduka: "Ahantu heza"
Kugira ngo amashanyarazi akore neza, ugomba gukora mu buryo bwihariye bw'amashanyarazi: urwego rw'umuyoboro w'amashanyarazi rudahinduka.
Mu murongo wa polarization (Ubucucike bw'ubu ugereranije na Voltage), ubona uturere dutandukanye:
1. Akarere gakora (Umuvuduko muke): Umuriro wiyongera bitewe n'amashanyarazi. Muri rusange, gukata ibintu mu buryo butaringaniye bibaho. Ibisubizo: Guturika no kurangiza nabi.
2. Akarere ka Passive/Plateau (Volteau nziza): Umuriro ugumaho nubwo ingufu z'amashanyarazi ziyongera. Urukuta rurerure rugenzura neza ikwirakwira ry'amashanyarazi. Ibisubizo: Gutunganya neza amashanyarazi, koroshya cyane, no kuyabyaza urumuri.
3. Akarere ka Transpassive (Umuvuduko mwinshi w'amashanyarazi): Umuyaga wongera kwiyongera. Ihindagurika rya ogisijeni n'ihindagurika ry'aho hantu (imiyoboro, imitsi ya gaze) bibaho. Ibisubizo: Gusukura cyane, kwangirika.
Amategeko agenga imikorere: Komeza ingufu z'uturemangingo zigufashe kuguma ku butaka bunini.
4. Ibipimo ngenderwaho by'imikorere n'imbogamizi
Kugira ngo ugere ku musaruro wo "kwibira mu buryo bwimbitse" mu myitozo, genzura ibi bintu:
● Ubushyuhe: Yongera umuvuduko wo gukwirakwira, igagabanya urwego runini. Igomba kuguma ihamye ($\pm 2^\circ C$). Ishyushye cyane → Irashya. Irakonje cyane → Irakenewe ingufu nyinshi, irahindagurika.
● Ubucucike bw'ubu: Ubusanzwe 10–50 A/$dm^2$. Bigenwa n'imiterere y'ibice. Hasi ku bice byoroshye.
● Igihe: Iminota 2–10 isanzwe. Igihe kirekire si cyo cyiza buri gihe; gusiga irangi rirenze urugero bishobora gutera imiyoboro.
● Igishushanyo cya Cathode: Igomba kwerekana imiterere y'ibice bigoye kugira ngo igumane uburyo bumwe bwo gukwirakwiza umuriro. "Ingufu zo guterera" ni mbi.
Ingaruka zisanzwe n'impamvu nyamukuru ziterwa n'amashanyarazi:
· Gusohora gaze: Ihindagurika ry’ikirere gishyuha cyangwa umwuka wa ogisijeni (akarere kanyuramo).
· Igishishwa cya Orange / Guteraho: Ikora mu gace gakora (voltage iri hasi cyane) cyangwa electrolyte yanduye (urugero, chloride).
· Gusukura mu buryo butangana: Gushyira cathode nabi cyangwa electrolyte nyinshi idakora neza (ibidahungabanya micro-layer viscous ariko bikongera ubwinshi bw'ibice byinshi).
Incamake: Uburyo bwo gufata amashanyarazi
Gutunganya hakoreshejwe electropolishing ni inzira yo gushonga mu buryo bugabanya ubwikorezi. Irangira neza ntirigerwaho binyuze mu "gutwika" imisozi ahubwo rigerwaho binyuze mu gushyiraho urwego rw'umupaka ruhamye kandi rurwanya imiterere y'ubutaka, rutuma habaho igipimo cyo gushonga kiri hejuru ku bintu bigaragara ku buso bugaragara. Gukorera neza ku gice cy'umugezi kidakora neza, hamwe na electrolyte ya aside ikozwe mu buryo bwihariye, bitanga ubuso bworoshye, busukuye, kandi butagira aho bubogamira kurusha ubundi buryo bwose bwa mekanike.
