Hari amavuta mu miyoboro y'amazi y'icyuma kidashonga nyuma yo kurangiza kuyitunganya, kandi agomba gutunganywa no kuyumishwa mbere yuko ibikorwa bikurikira bitangira gukorwa.
1. Kimwe ni ugusuka icyo gikoresho cyo gusiga amavuta muri pisine, hanyuma ukongeramo amazi hanyuma ukacyinjiza mu mazi. Nyuma y'amasaha 12, ushobora kugisukura neza.
2. Indi nzira yo gusukura ni ugushyira umuyoboro w'icyuma gisukura mu mavuta ya mazutu, ukawushyira mu mazi amasaha 6, hanyuma ukawushyira mu kidendezi gifite isuku, ukawushyira mu mazi amasaha 6, hanyuma ukawusukura.
Uburyo bwa kabiri bufite ibyiza bifatika. Ni bwiza gusukura imiyoboro y'isuku y'icyuma kidashonga.
Iyo gukuraho amavuta bidasukuye cyane, bizagira ingaruka zigaragara ku gikorwa cyo gusiga amavuta no kuyakoresha mu gukaraba. Iyo gukuraho amavuta bidasukuye, mbere ya byose, kuyasukura bizagorana kandi kuyasukura ntibizaba bishyushye.
Icya kabiri, nyuma y'uko urumuri rurangiye, ibicuruzwa bizahita bikurwaho byoroshye, ibyo bikaba bitakwemeza ko ibicuruzwa bizaba byiza cyane.
Kugira ngo imiyoboro itunganye neza mu byuma bidakoresha icyuma gifunganye bisaba ko itunganywa
Isura nziza, umwobo w'imbere woroshye:
Umuyoboro w'icyuma gikozwe mu buryo bwa "stainless steel" ukozwe mu buryo bwa "finished-stainless steel" imbere no hanze. Ubuso bw'imbere n'inyuma bwa "Ra≤0.8μm"
Ubuso bw'imbere n'inyuma by'umuyoboro urimo irangi bushobora kugera kuri Ra≤0.4μm (nk'ubuso bw'indorerwamo)
Muri rusange, ibikoresho by'ingenzi byo gusiga neza imiyoboro y'icyuma gikozwe mu byuma bitagira umugese ni umutwe uhanagura, kuko ubukana bw'umutwe uhanagura bugena uko gusiga neza bigenda.
Impamyabumenyi y'icyiciro cya kabiri cya kaminuza (BA):Annealing y'Icyatsi. Mu gihe cyo gushushanya umuyoboro w'icyuma, bizakenera amavuta yo kwisiga, kandi ibinyampeke nabyo bizahinduka bitewe no gutunganya. Kugira ngo wirinde ko aya mavuta aguma mu muyoboro w'icyuma, uretse gusukura umuyoboro w'icyuma, ushobora kandi gukoresha gaze ya argon nk'ikirere kiri mu itanura mu gihe cyo gushyushya ubushyuhe bwinshi kugira ngo ukureho guhindagurika, no gukomeza gusukura umuyoboro w'icyuma uhuza argon na karubone na ogisijeni ku buso bw'umuyoboro w'icyuma kugira ngo bitwike. Ubuso butanga umusaruro mwiza, bityo ubu buryo bwo gukoresha argon annealing nziza kugira ngo bushyuhe kandi bukonje vuba ubuso butangaje bwitwa glow annealing. Nubwo gukoresha ubu buryo kugira ngo umurike ubuso bishobora kwemeza ko umuyoboro w'icyuma usukuye neza, nta kwanduzanya kw'inyuma. Ariko, urumuri rw'ubu buso ruzamera nk'ubuso budafite matte ugereranije n'ubundi buryo bwo gusya (mekanike, chimique, electrolytic). Birumvikana ko ingaruka zifitanye isano n'ibiri muri argon n'inshuro zo gushyushya.
EP:gushushanya hakoreshejwe amashanyarazi (Electro Polishing), polishing ya electrolytic ni ugukoresha uburyo bwo gutunganya anode, hakoreshejwe ihame rya electrochimie kugira ngo uhindure neza voltage, amashanyarazi, imiterere ya aside, n'igihe cyo gupolisha, ntabwo ari ugutuma ubuso bugaragara kandi bunoze gusa, ingaruka zo gusukura zishobora no kunoza ubudahangarwa bw'ubuso, bityo ni bwo buryo bwiza bwo gukarishya ubuso. Birumvikana ko ikiguzi cyabwo n'ikoranabuhanga nabyo biriyongera. Ariko, kubera ko polishing ya electrolytic izagaragaza imiterere y'umwimerere y'ubuso bw'icyuma, niba hari imikoki ikomeye, imyobo, ibintu bivanze n'ibisigazwa, nibindi ku buso bw'icyuma, bishobora gutuma electrolysis inanirwa. Itandukaniro riva ku polishing ya shimi ni uko nubwo ikorerwa ahantu hari aside, ntabwo gusa hazabaho ingese ku buso bw'icyuma, ahubwo n'ubunini bwa chromium oxide film ku buso bushobora no kugenzurwa kugira ngo hagerwe ku budahangarwa bwiza bw'ubudahangarwa bw'ubudahangarwa bw'icyuma.
