Dufite ingingo z'ingenzi hagati y'ibikoresho bibiri (icyuma cyoroshye cyangwa icyuma kidashonga) hepfo. Icyuma kidashonga kirakomera cyane mu gihe cy'umunyu kandi gishobora gukoreshwa mu nganda z'ibiribwa, mu gihe icyuma cyoroshye gikomeye kandi gishobora gushyira igitutu kinini ku ikoreshwa ry'inyo.

icyuma cyoroshye:
Icyuma cyoroshye, kizwi kandi nka icyuma cya karuboni, ni cyo cyuma gikunze gukoreshwa cyane mu bikorwa byose, kandi imigozi yo gufunga imiyoboro nayo ni uko. Ni kimwe mu byuma binini bigizwe n'imiterere itandukanye ya mekanike. Ibi bivuze ko gusobanukirwa no kugena urwego rukwiye bishobora kugira ingaruka zikomeye ku mikorere y'umusaruro urangiye. Urugero, imihangayiko n'ibisabwa ku mpapuro z'icyuma zigize ibicapo by'imodoka bitandukanye cyane n'iby'ibikoresho byo gushyiramo imiyoboro. Mu by'ukuri, uburyo bwiza bwo gufunga imiyoboro ntabwo bungana n'ubw'igikonoshwa n'imigozi.

Imbogamizi imwe y'icyuma cyoroshye ni uko gifite ubushobozi buke bwo kurwanya ingese karemano. Ibi bishobora gukemurwa hakoreshejwe irangi, akenshi zinc. Itandukaniro mu buryo bwo gusiga n'amahame bivuze ko kurwanya ingese bishobora kuba ahantu hamwe aho imiyoboro y'amazi itandukana cyane. Ihame ry'Ubwongereza ku miyoboro y'amazi isaba amasaha 48 yo kurwanya ingese itukura igaragara mu isuzuma rya 5% ry'umunyu utagira aho ubohera, kandi ibicuruzwa byinshi bya kite bitarashyirwamo ikimenyetso ntibishobora kuzuza iki gisabwa.

Icyuma kidasembuye:
Ibyuma bitazangiza ibyuma biragoye kurusha ibyuma byoroheje mu buryo bwinshi, cyane cyane iyo bigeze ku byuma bifunga imiyoboro y'amazi, kuko abakora ibikoresho bihenze bakoresha ubwoko butandukanye bw'ibikoresho kugira ngo bahe ibicuruzwa ikiguzi cyo kubitunganya gito kandi imikorere igabanuke.

Inganda nyinshi zikora imiyoboro y'amazi zikoresha icyuma gifunga imiyoboro ya ferritic nk'igisimbura icyuma cyoroshye cyangwa nk'igisimbura icyuma gihendutse cya austenitic. Bitewe n'uko hari chromium muri alloy, ibyuma bya ferritic (bikoreshwa mu byiciro bya W2 na W3, mu byiciro bya 400) ntibisaba ubundi buryo bwo gutunganya kugira ngo byongere ubudahangarwa bw'ingufu. Ariko, kuba iki cyuma kidafite cyangwa gifite nikeli nkeya bivuze ko imiterere yacyo iri hasi cyane ugereranyije n'ibyuma bifunga imiyoboro ya austenitic.

Ibyuma bita "stainless steel" bya Austenitic bifite urwego rwo hejuru rwo kurwanya ingese ku bwoko bwose bwa ingese, harimo na aside, bifite ubushyuhe bwinshi bwo gukora, kandi ntibikoresha "magnetic". Muri rusange hari urwego rwa 304 na 316 rw'ibyuma bita "stainless steel"; ibikoresho byombi byemewe gukoreshwa mu mazi ndetse n'icyemezo cya Lloyd's Register, mu gihe ingano ya ferritic idashobora gukoreshwa. Izi ngano zishobora no gukoreshwa mu nganda z'ibiribwa n'ibinyobwa, aho aside nka aside acetic, citric, malic, lactic na tartarique zishobora kutemera ikoreshwa rya ferritic steel.
