Gukoresha amashanyarazi hejuru

Amashanyarazi nuburyo buryo ibyuma biva muri electrolyte nigikorwa cyumuyaga washyizwe hanyuma ugashyirwa hejuru yikintu kugirango ubone icyuma gitwikiriye.

Galvanised:
Zinc yangirika byoroshye muri acide, alkalis, na sulfide.Igice cya zinc muri rusange.Nyuma ya passivation mugisubizo cya chromate, firime ya passivation yakozwe ntabwo yoroshye gukorana numwuka utose, kandi ubushobozi bwo kurwanya ruswa bwongerewe cyane.Mu kirere cyumye, zinc irahagaze neza kandi ntabwo byoroshye guhindura ibara.Mu mazi no mu kirere cyuzuye, ikorana na ogisijeni cyangwa karuboni ya dioxyde de okiside cyangwa firime ya karubone ya karubone ya alkaline, ishobora kubuza zinc gukomeza okiside kandi ikagira uruhare mu kurinda.
Ibikoresho bikoreshwa: ibyuma, ibice byicyuma

chrome:
Chromium ihagaze neza cyane mu kirere cyuzuye, alkali, aside nitric, sulfide, ibisubizo bya karubone na acide kama, kandi irashobora gushonga byoroshye muri aside hydrochloric na acide sulfurike ishyushye.Ikibi nuko bigoye, byoroshye, kandi byoroshye kugwa.Chromium itaziguye hejuru yibice byibyuma nkurwego rwo kurwanya ruswa ntabwo ari byiza.Mubisanzwe, amashanyarazi menshi (nukuvuga isahani y'umuringa → nikel → chromium) irashobora kugera ku ntego yo gukumira ingese.Kugeza ubu, irakoreshwa cyane mu kunoza imyambarire y’ibice, ingano yo gusana, kwerekana urumuri no gushushanya.
Ibikoresho bikoreshwa: ibyuma bya ferrous, umuringa n'umuringa alloy zeru zishushanya chrome isahani, isahani idashobora kwambara

Isahani y'umuringa:
Umuringa ntabwo uhagaze mu kirere, kandi icyarimwe, ifite imbaraga nziza kandi ntishobora kurinda ibindi byuma kwangirika.Nyamara, umuringa ufite amashanyarazi menshi, igipande cyumuringa kirakomeye kandi cyiza, gihujwe neza nicyuma cyibanze, kandi gifite imikorere myiza yo gusya.Bisanzwe bikoreshwa mugutezimbere ubwiza bwibindi bikoresho, nkigice cyo hasi cya andi mashanyarazi, nkigice cyo gukingira kugirango wirinde carburisation, no kugabanya guterana cyangwa gushushanya ku cyuma.

Ibikoresho bikoreshwa: icyuma cyumukara, umuringa n'umuringa wavanze nikel-isahani, hasi ya chrome.

Isahani ya Nickel:
Nickel ifite imiterere ihamye yimiterere yikirere na lye, kandi ntabwo byoroshye guhindura ibara, ariko biroroshye gushonga muri acide ya nitricike.Biroroshye kunyura muri acide nitricike yibanze, kandi ibibi byayo ni porosity.Kugira ngo utsinde iyi mbogamizi, ibyuma byinshi birashobora gukoreshwa, na nikel nigice cyo hagati.Igice cya nikel gifite plaque gifite ubukana bwinshi, cyoroshye guhanagura, gifite urumuri rwinshi kandi rushobora kongera isura no kurwanya, kandi gifite kurwanya ruswa.
Ibikoresho bikoreshwa: birashobora kubikwa hejuru yibikoresho bitandukanye, nka: ibyuma bivangwa na nikel bishingiye ku byuma, ibinyomoro bishingiye kuri zinc, ibishishwa bya aluminiyumu, ibirahuri, ububumbyi, plastike, imashanyarazi n’ibindi bikoresho

Amabati:
Amabati afite imiti ihamye.Ntibyoroshye gushonga mumashanyarazi ya acide sulfurike, aside nitric na aside hydrochloric.Sulfide nta ngaruka igira ku mabati.Amabati nayo ahamye muri acide kama, kandi ibiyigize ntabwo ari uburozi.Ikoreshwa cyane mubikoresho byinganda zibiribwa nibice byindege, kugendana nibikoresho bya radio.Irashobora gukoreshwa kugirango wirinde insinga z'umuringa kutagira ingaruka kuri sulferi muri reberi kandi nk'urwego rwo gukingira hejuru ya nitriding.
Ibikoresho bikoreshwa: icyuma, umuringa, aluminium hamwe nibisigazwa byabo

Amabati y'umuringa:
Umuringa-tin alloy electroplating ni ugushiraho umuringa-tin uvanze kubice bitarimo nikel, ariko ugashyiraho chromium.Nickel nicyuma gisa nkidasanzwe kandi cyagaciro.Kugeza ubu, amashanyarazi-tin alloy electroplating akoreshwa cyane mu nganda zikoresha amashanyarazi mu gusimbuza nikel, ifite ubushobozi bwo kurwanya ruswa.
Ibikoresho bikoreshwa: ibice byibyuma, umuringa nu muringa ibice.
