Chrome yashizwemo ibyumaBishyizwe hamwe nicyuma hejuru yicyuma cyicyuma binyuze mumashanyarazi.Intego yingenzi ya chromium yashizwemo ibyuma ni uburinzi.Imiyoboro ya Chromium isize ibyuma bifite imiti ihamye kandi ntigire icyo ikora muri alkali, sulfide, aside nitric, na acide nyinshi.Imiyoboro ya Chromium isize ibyuma irashobora gushonga muri aside hydrochloride (nka aside hydrochloride) na acide sulfurike ishyushye.Icya kabiri, isahani ya chromium ifite imbaraga zo kurwanya ubushyuhe, kandi imiyoboro ya chromium yashizwemo ibyuma gusa oxyde kandi igahindura ibara mugihe ubushyuhe burenze dogere selisiyusi 500.Byongeye kandi, coefficente ye yo guterana, cyane cyane coefficente yumye yumye, niyo yo hasi cyane mubyuma byose, kandi imiyoboro ya chrome isize ibyuma ifite imbaraga zo kwihanganira kwambara.Mu mucyo ugaragara, ubushobozi bwo kwerekana chromium bugera kuri 65%, hagati ya feza (88%) na nikel (55%).Chromium ntabwo ihindura ibara, kandi imiyoboro ya chrome isize ibyuma irashobora kugumana ubushobozi bwayo bwo kwerekana igihe kirekire iyo ikoreshejwe, ikaba nziza kuruta ifeza na nikel.Hariho ubwoko butatu bwa chrome yubatswe.
1. Kurinda - Kurinda Chromium Gushiraho Kurinda - Gushushanya Chromium Decorative, bizwi cyane nka Decorative Chromium, bifite igipande cyoroshye kandi cyiza gisanzwe gikoreshwa nkigice cyo hanze cya electroplating nyinshi.Kugirango ugere ku ntego zo gukingira, urwego ruciriritse rwuzuye rugomba kubanza gushirwa kuri zinc ishingiye cyangwa munsi yicyuma, hanyuma hagashyirwaho urwego rwagati rwa 0.25-0.5 rugomba gushyirwaho hejuru yacyo μ Chromium yoroheje ya m.Uburyo bukunze gukoreshwa harimo Cu / Ni / Cr, Ni / Cu / Ni / Cr, Cu Sn / Cr, nibindi.Ntabwo ihindura ibara nyuma yo kumara igihe kinini ikirere.Ubu bwoko bwo gutwikira bukoreshwa cyane mukurinda no gushushanya ibice nkimodoka, amagare, imashini zidoda, amasaha, ibikoresho, nibikoresho bya buri munsi.Igice cya chromium gisize neza gifite ubushobozi buke bwo kwerekana urumuri kandi gishobora gukoreshwa nkigaragaza.Gushira poro ya micro cyangwa microcracks ya chromium kuri nikel-etage nyinshi ni inzira yingenzi yo kugabanya umubyimba wuzuye wikibiriti no kubona uburyo bwo gushushanya burinda ruswa.Nicyerekezo cyiterambere cyibikorwa bigezweho bya electroplating.
2. Isahani ikomeye ya chromium (idashobora kwihanganira chromium) ifite ubukana bukabije kandi ikananirwa kwambara, ishobora kongera igihe cyakazi cyibikorwa byakazi, nko gukata no gushushanya, gukanda no guteramo ibishushanyo byibikoresho bitandukanye, ibyuma, ibiti, ibipimo, ibikoresho , nibindi, kandi birashobora no gukoreshwa mugusana kwihanganira ibipimo byibice byambarwa.Ubunini bwa plaque chromium isanzwe ni 5-50 μ m.Irashobora kandi kugenwa ukurikije ibikenewe, bimwe bingana na 200-800 μ M. M. Chromium ikomye ku byuma ntibisaba gutwikirwa hagati.Niba hari ibisabwa byihariye byo kurwanya ruswa, impuzu zitandukanye zirashobora kandi gukoreshwa.
3. Amata yera ya chromium yera yuzuye ni amata yera, afite ububengerane buke, ubukana bwiza, ububobere buke, nibara ryoroshye.Ubukomezi bwabwo buri munsi yubwa chromium ikomeye hamwe na chromium ishushanya, ariko ifite imbaraga zo kurwanya ruswa, bityo ikoreshwa cyane mugupima ibikoresho nibikoresho byerekana ibikoresho.Kugirango irusheho gukomera, urwego rwa chromium rukomeye, ruzwi kandi nka chromium ebyiri, rushobora gutwikirwa hejuru y’amata yera yera, rukomatanya ibiranga amata yera ya chromium yera hamwe na chromium ikomeye.Bikunze gukoreshwa mugutwikiriye ibice bisaba kwihanganira kwambara no kurwanya ruswa.
4. Isahani ya chromium isukuye (chromium porous) ikoresha ibiranga ibice byiza muri chromium ubwayo.Nyuma yo gushira chromium ikomeye, ubukanishi, imiti, cyangwa amashanyarazi yamashanyarazi arakorwa kugirango arusheho kwimbuka no kwagura urusobe.Ubuso bwurwego rwa chromium butwikiriwe na groove nini, idafite gusa ibiranga chromium idashobora kwihanganira kwambara, ahubwo inabika neza itangazamakuru risiga amavuta, ikarinda imikorere idasize amavuta, kandi ikanoza ubushyamirane no kwambara kurwego rwakazi.Bikunze gukoreshwa mugushiraho ubuso bwibice byo Kunyerera munsi yumuvuduko ukabije, nkicyumba cyimbere cya moteri yaka imbere ya moteri ya silinderi, impeta ya piston, nibindi.
⑤ Gufata chromium yumukara chromium yumukara ifite urumuri rumwe, gushushanya neza, no kuzimangana neza;Ubukomezi buri hejuru (130-350HV), kandi kwihanganira kwambara bikubye inshuro 2-3 ugereranije na nikel yaka munsi yubugari bumwe;Kurwanya kwangirika kwayo ni kimwe na chromium isanzwe isanzwe, bitewe ahanini nubunini bwurwego rwagati.Kurwanya ubushyuhe bwiza, nta bara munsi ya 300 ℃.Igice cya chromium cyirabura gishobora gutwikirwa hejuru yicyuma, umuringa, nikel, nicyuma.Kugirango urusheho kurwanya ruswa hamwe ningaruka zo gushushanya, umuringa, nikel, cyangwa umuringa w'amabati urashobora kandi gukoreshwa nkigice cyo hasi, kandi igishishwa cya chromium cyirabura gishobora gushyirwaho hejuru yacyo.Ububiko bwa chromium yumukara bukoreshwa muburyo bwo kurinda no gushushanya ibice byibikoresho byindege hamwe nibikoresho bya Optical, imirasire yizuba yizuba nibikenerwa bya buri munsi
