Kumenyekanisha icyuma kidafite ingese

Isahani idafite ibyuma ifite ubuso bworoshye, plastike ndende, ubukana nimbaraga za mashini, kandi irwanya ruswa na acide, gaze ya alkaline, ibisubizo nibindi bitangazamakuru.Nicyuma kivanze kidashobora kwangirika byoroshye, ariko kitarangwamo ingese.Isahani idafite ibyuma bivuga isahani yicyuma irwanya ruswa n’ibitangazamakuru bidakomeye nkikirere, umwuka n’amazi, mu gihe icyuma kirwanya aside bivuga icyuma cyihanganira ruswa n’ibitangazamakuru byangiza imiti nka aside, alkali, n'umunyu.Isahani idafite ibyumaimaze imyaka isaga ijana kuva yasohotse mu ntangiriro z'ikinyejana cya 20.

Isahani idafite ibyuma muri rusange ni ijambo rusange kubisahani byuma bidafite ibyuma na plaque irwanya aside.Yatangijwe mu ntangiriro z'iki kinyejana, iterambere ry'icyuma kidafite ingese ryashyizeho urufatiro rukomeye rw'ibikoresho na tekiniki mu iterambere ry'inganda zigezweho n'iterambere ry'ubumenyi n'ikoranabuhanga.Hariho ubwoko bwinshi bwibyuma bidafite ingese hamwe nibintu bitandukanye.Yagiye ikora ibyiciro byinshi mubikorwa byiterambere.

Ukurikije imiterere, igabanijwemo austenitisicyuma( ibyuma bya austenitike bifite imbaraga zo kurwanya ruswa, ibintu byiza byubukanishi nibikorwa byiza) , icyuma cya martensitike kitagira ibyuma (harimo imvura igwa icyuma kidafite icyuma,ni ubwoko bwuburyo bushobora kuvurwa ubushyuhe Ibyuma imikorere ihinduwe ifite imbaraga nubukomezi), ferriticicyuma( imbaraga nyinshi, imirimo ikonje yo hasi ikomera, kurwanya cyane chloride ihangayitse, kwangirika kwangirika, kwangirika kwa crevice nibindi byangirika byaho.) , Hariho ibyiciro bine byingenziof ibyuma bya austenitike na ferritic duplex idafite ibyuma, bishyirwa mubyiciro ukurikije ibice byingenzi bya shimi biri mu isahani yicyuma cyangwa ibintu bimwe na bimwe biranga icyapa, kandi bigabanijwemo ibyuma bya chromium bitagira ibyuma, ibyuma bya chromium-nikel, na chromium-nikel -molybdenum isahani idafite ibyuma.Kandi ibyuma bya karubone nkeya, ibyuma bya molybdenum bitagira umuyonga, ibyuma byinshi bitagira umwanda nibindi.
