1. Ikintu cyoroshye cyo kuzimya ni iki
Ibyo bita kuzimya ingingo yoroheje ni ahantu horoheje hatazima ku bice.Nuko rero, nanone yitwa point point yoroshye (softspot) .Icyerekezo cyoroshye cyo kuzimya amazi kirakomeye kuruta icy'amavuta azimya, kuko hejuru ifite firime ya parike. kugabanya umuvuduko wo gukonja. Iki kintu gikunze kwitwa Leiden ubukonje bwa Leiden.Nubwo kuzimya amavuta ari ubukana budahagije, ni ukuvuga kuzimya bidahagije, ariko ntibyoroshye gutera kuzimya ingingo yoroshye.Nyamara, kuzimya aho decarbonisation cyangwa uruhu rwa okiside ni kimwe no kuzimya ingingo yoroshye.
Bavuga ko mugihe cyimvura yimvura ikunda kuzimya ingingo yoroshye, niba ubuhehere bwikibanza kizimya burenze 55%, bukunze kuzimya ingingo yoroshye.
Ubuso bwibice byinshi byo kuzimya bikunda guhura ninkovu, cyangwa icyuma cyabayapani cyicyuma, amabara meza arimo kuzimya ingingo yoroshye. Microtissue yumwanya woroshye ni martensite wongeyeho pearlophyte yoroheje cyane (flexular nodular) ifite ibara ryiza.
2. Nigute ushobora kubona kuzimya ingingo yoroshye
Mubusanzwe hariho uburyo butatu bwo kubona ingingo zoroshye zazimye.Uburyo bwa mbere nukubona ibara ryoroshye rya tawny hejuru yo gusya: uburyo bwa kabiri nuko uburyo bwa gatatu ari ugukoresha aside yangirika kugirango ubone ingingo yoroshye yo kuzimya;ni ukuvuga, gushira ibice muri 50% ya hydrochloric acide yamazi (amazi atose) kugirango yangirwe, niba igice cyigice gisa nikibara cyirabura, ikibara cyumukara nikintu cyoroshye kizimya.Nyamara, twakagombye kumenya ko ubushyuhe buke (180) ~ 200C) ibice byangirika ahantu hakomye, kandi ibara ahantu hatabangamiwe. Ubujyakuzimu bwurwego rwazimye burashobora gupimwa ukoresheje ubu buryo.
3. Nigute wakwirinda kuzimya kuva ahantu horoheje
Kugirango wirinde kuzimya ingingo zoroshye, ntugahagarike okiside cyangwa decarbonize ibice mugihe ushushe mbere. Icya kabiri, kugirango wirinde ubuso bwibice bifatanye na firime yumuyaga wamazi, nibyiza kubyutsa byuzuye amazi azimya hanyuma ugakoresha spray kumazi kuri gukonja. Mubyongeyeho, niba kuzimya n'amazi yumunyu 10% birashobora gukumira burundu kuzimya ingingo zoroshye. Byongeye kandi, gushira urwego ruto rwifu ya polishinge hejuru yibice bizimya nuburyo bwiza bwo gukumira kuzimya byoroshye ingingo. Ifu yo gusya yakonje vuba kurusha ibyuma bidafunze kandi ntibizimya ingingo yoroshye, bityo rero gukoresha ifu ya polishinge mugikorwa cyo kuzimya icyuma cyabayapani nuburyo bwibanga.Ariko bigomba gufatwa.Niba ifu yo gusya ari ndende cyane, gukonja biratinda, ntabwo bigoye.
Ifu yo gusya iroroshye kandi igashyirwa hejuru yibice bizimya, kandi iyo kuzimya, ubuso ntibuzengurutswe na firime ya parike, ihinduka ibibyimba bito kandi bikazamuka cyane, bityo bikonja vuba.
Nkumukozi wambara, usibye ifu yo gusya.Ivu hamwe na kaolin n'amazi;mika idafite ibumba ryoroshye namazi: pumice hamwe nibumba ryoroshye namazi, ibi bivugwa ko ari resept nziza.
Vuba aha, igisubizo cyo kuzimya amazi-igisubizo (polymer quenching solution) gikoreshwa cyane aho kuzimya amavuta, afite imbaraga zidasanzwe kandi gishobora gukora firime hejuru iyo ishyutswe nibice bivuwe.Iyo ubushyuhe bugabanutse kugera kuri 90 ℃ (ibisubizo bimwe ni 74 ℃), mask yo hejuru irashonga.Nuko rero, gukonjesha mubushyuhe bwo hejuru birashobora gukorwa neza kugirango birinde kuzimya ingingo zoroshye.Ingaruka ni nziza nk gukoresha ifu ya polishing hamwe nayo}
Byongeye kandi, niba gukonjesha ultrasonic "ibyumweru 25000 / s), firime yumuyaga nayo irashobora gukurwaho neza, bityo kuzimya ingingo yoroshye nabyo birashobora gukumirwa. Gukonjesha Ultrasonic nuburyo bushya bwo gukonjesha.
