Ibyuma bitagira umuyonga ni ibyuma bivangwa na chromium byibuze 10.5%. Chromium ikora hamwe na ogisijeni mu kirere ikora urwego rukingira rutuma ibyuma bitagira umwanda birwanya ruswa kandi ingese. Kuri ubu, ku isoko hari ubwoko burenga 150 bwibyuma bitagira umwanda.

Kubera imiterere mike yo kubungabunga, kurwanya okiside no kwanduza, ibyuma bitagira umwanda bikundwa mubikorwa byinshi, cyane cyane aho ibyiza byuburanga.

Ndetse hamwe nibi bintu bitangaje, ibyuma bidafite ingese birashobora kandi bigakora ingese nyuma ya byose, ni 'umwanda' ntabwo 'bitagira umwanda'. Ubwoko bumwebumwe bwibyuma bidafite ingese bikunda kwangirika kurenza ubundi, bitewe nibirimo chromium. Iyo chromium iri hejuru, ntabwo icyuma gishobora kubora.

Ariko, igihe kirenze kandi niba kidakomeje neza, ingese irashobora kandi gutera imbere kumyuma idafite ingese.

Ibintu bigira ingaruka kuri Rust kuri Steel

Ibintu bitandukanye birashobora kugira ingaruka kubushobozi bwibyuma bidafite ingese zo kurwanya ruswa. Ibigize ibyuma nimwe gihangayikishije cyane mugihe cyo kurwanya ruswa. Ibintu mubyiciro bitandukanye byibyuma bitagira umwanda birashobora kugira ingaruka mbi mukurwanya ruswa.

Ibidukikije aho ibyuma bikoreshwa ni ikindi kintu gishobora kongera amahirwe yo kwangirika kwicyuma. Ibidukikije hamwe na chlorine nkibidendezi byo koga byangirika cyane. Nanone, ibidukikije bifite amazi yumunyu birashobora kwihuta kwangirika kwicyuma.

Hanyuma, kubungabunga bizagira ingaruka kubushobozi bwicyuma cyo kurwanya ingese. Chromium iri mu byuma bitagira umwanda ifata umwuka wa ogisijeni mu kirere kugira ngo ikore chromium oxyde irinda hejuru. Nubwo binanutse cyane, iki gipimo nicyo kirinda ibyuma kwangirika. Uru rupapuro rushobora gusenywa n’ibidukikije bikaze cyangwa kwangirika kw’imashini nko gushushanya nyamara, iyo bisukuwe neza kandi ahantu heza, urwego rukingira ruzongera gukora ibintu bigamije kurinda ibintu.

Ubwoko bwibyuma bitangirika

Hariho ubwoko butandukanye bwibyuma bitangirika. Buri kimwe muri byo kigaragaza ibibazo bitandukanye kandi bisaba gukemura bitandukanye.

• Ruswa rusange - nibiteganijwe kandi byoroshye gukemura. Irangwa no gutakaza kimwe kubuso bwose.
• Ruswa ya Galvanic - ubu bwoko bwa ruswa bugira ingaruka kumyuma myinshi. Yerekeza ku bihe icyuma kimwe gihura nikindi kandi kigatera umwe cyangwa bombi kwitwara hamwe no gukosora.
• Gutera ruswa - ni ubwoko bwaho bwangirika busiga imyenge cyangwa umwobo. Yiganje mubidukikije birimo chloride.
• Kwangirika kwa Crevice - nanone kwangirika kwagaragaye kugaragara kumurongo hagati ibiri ihuza ubuso. Birashobora kubaho hagati yibyuma bibiri cyangwa icyuma nicyuma.

Nigute wakwirinda ibyuma bitagira umwanda

Ibyuma bidafite ingese birashobora kuba impungenge kandi bisa neza. Icyuma cyagenewe kurwanya ruswa niyo mpamvu abakoresha benshi bafite ubwoba mugihe batangiye kubona irangi no kubora ku cyuma. Ku bw'amahirwe, hari uburyo butandukanye mubyiciro bitandukanye bishobora gufasha kunoza ingese no kurwanya ruswa.

Igishushanyo

Kwitegura mugihe cyicyiciro cyo gutegura, mugihe ukoresheje ibyuma bitagira umwanda, birashobora kwishyura mugihe kirekire. Menya neza ko icyuma gikoreshwa ahantu hafite amazi make kugirango ugabanye kwangirika hejuru. Mugihe aho byanze bikunze guhura namazi, hagomba gukoreshwa umwobo wamazi. Igishushanyo kigomba kandi kwemerera kuzenguruka ikirere kubuntu kugirango birinde kwangirika.

Ibihimbano

Mugihe cyo guhimba, hagomba kwitabwaho bidasanzwe ibidukikije kugirango wirinde kwanduza ibindi byuma. Ibintu byose uhereye kubikoresho, kubika ibikoresho, guhinduranya iminyururu n'iminyururu bigomba gukurikiranwa neza kugirango bitagwa umwanda mubi. Ibi birashobora kongera imbaraga zo gushiraho ingese.

Kubungabunga

Amavuta amaze gushyirwaho, kubungabunga buri gihe ni urufunguzo rwo kwirinda ingese, binagabanya iterambere ry ingese zose zishobora kuba zimaze kuba. Kuraho ingese zakozwe ukoresheje uburyo bwa mashini cyangwa imiti hanyuma usukure amavuta ukoresheje amazi ashyushye hamwe nisabune. Ugomba kandi gupfuka icyuma ukoresheje ingese irwanya ingese.
