Igipfunyika cya nikeli cya 1149 cy'umuhoro

▪ Iyi gahunda igaragaza imbaraga zidasanzwe zo guterera, bigatuma habaho gushyira ibintu bimwe ndetse no mu buso bugoye no mu byumba by’imbere. Ubuziranenge bw’ubwogero bugumaho mu gihe kirekire, hamwe no kubora guke kw’inyongera za organic, bituma habaho ireme rihoraho ryo guterera. Uburyo bwa electrolyte burimo ibintu byihariye bitanga urumuri n’ibintu bipima ingano bikongera imbaraga zo guterera, bigatuma ubuso burushaho kuba bwiza kandi bugaragara.

▪ Iyi gahunda ijyanye n'imiterere y'aho ibyuma bishyirwa n'aho bishyirwa, itanga ubushobozi bwo gukora ibintu bitandukanye mu bunini n'ingano. Ubwogero bukora neza mu bushyuhe bunini, ubusanzwe buri hagati ya 45°C na 65°C, bushobora guhindurwa hashingiwe ku bisabwa byihariye. Igipimo cya pH kigenzurwa neza mu bunini buto, ubusanzwe kiri hagati ya 3.8 na 4.5, kugira ngo hakorwe neza imiterere y'aho bishyirwa n'aho bitwikiriye.

▪ Ingano ya nikeli mu gikoresho cyo gupfuka igumana hagati ya 70 na 90 g/L, mu gihe iyoni za chloride zigumana hagati ya 10 na 20 g/L kugira ngo habeho kwangirika no gutwara neza kwa anode. Gukoresha anode za nikeli zifite isuku nyinshi, hamwe n'udufuka twa anode, bigabanya kwinjira kw'imyanda n'uduce duto mu bwogero.

▪ Ubu buryo bukoresha sisitemu zigezweho zo kuyungurura, ubusanzwe zikoresha utuzudu twa micron 5 kugeza kuri 10, kugira ngo zikureho ibintu byose bihagaze kandi bikomeze kugira ubuziranenge bw'ubwogero. Isuzuma risanzwe rya Hull cell rikorwa kugira ngo harebwe imikorere y'ubwogero no guhindura ingano y'inyongera uko bikenewe. Uburemere bw'urukiramende rwa nikeli rwashyizwemo bukunze kurenza 8%, nk'uko bipimwa n'ikizamini cya spiral contractometer, bigamije kwemeza imikorere myiza mu bikorwa byo gushushanya nyuma yo gushyiramo plati.

▪ Ubukana bw'igitambaro bushobora guhindurwa hagati ya 250 na 450 HV binyuze mu guhindura ibipimo byo kwiyuhagira n'ibipimo by'inyongera, bigatuma gikoreshwa mu nganda zitandukanye. Iyi gahunda igaragaza imiterere myiza yo gufatana, aho ibizamini by'imbaraga z'igishishwa bihora birenga 8 N/mm². Ubudahangarwa bw'ingufu z'umunyu, nk'uko byagenzuwe n'igerageza rya spray y'umunyu, ubusanzwe burenga amasaha 96 kugeza ku ingufu z'umweru n'amasaha 200 kugeza ku ingufu z'umutuku iyo zifunze neza.

▪ Imbaraga zidasanzwe zo gusuka amazi mu bwogero, akenshi zirenga 80% nk'uko bipimwe na Haring-Blum cell, zituma ubugari bw'igitambaro bukwirakwira neza. Iyi gahunda igira akamaro cyane ku bice bifite igipimo cyo hejuru, aho ubugari buhinduka buri munsi ya 15% ku gice cy'umurimo. Uburemere buke bw'imbere bw'aho amazi ashyirwa, akenshi buri munsi ya 10 MPa nk'uko bipimwe na spiral contractometer, bigabanya ibyago byo kwangirika cyangwa gucikagurika.

▪ Iyi gahunda ikubiyemo uburyo bwo kugenzura mu gihe nyacyo ibipimo by'ingenzi nk'ubushyuhe, pH, n'ubwinshi bw'icyuma, bigatuma habaho ubuziranenge buhoraho bwo gupfunyika. Gukoresha inyongeramusaruro zigezweho zifite imiterere yigenga bigira uruhare mu kumara igihe kirekire mu bwogero, akenshi birenga MTO 12 (ihindagurika ry'ibyuma) nta kwangirika gukomeye mu bwiza bw'igipfunyika. Iyi gahunda igamije kuzuza amahame akomeye y'inganda, harimo na ASTM B689 na ISO 1456 ku bipimo bya nickel bya electrodepositioned.
