Akamaro k'ibirimo bya Chromium mubyuma bitagira umwanda

Ibyuma bitagira umwanda bizwiho kuramba, kurwanya ruswa, no gushimisha ubwiza. Ariko, ibyuma byose ntabwo bishobora gusaba prefix izwi "stainless". Ikintu kimwe cyingenzi kigaragaza niba ibyuma byujuje ibisabwa bitarimo ingese ni chromium.

Chromium igira uruhare runini muguhindura ibyuma bisanzwe mubyuma. Kugirango ubone umutwe udafite ingese, ibyuma bigomba kuba bifite byibuze ijanisha rya chromium. Mu bihe byinshi, ibyuma bidafite ingese bisaba byibura 10.5% bya chromium kugirango ibuze ingese neza. Uru rugabano rushyiraho urufatiro rwibyuma bitangirika, bigatuma bikoreshwa mubikorwa bitandukanye.

Kwiyongera kwa chromium mubyuma birema oxyde ikingira hejuru, izwi nka pasiporo. Uru rupapuro rukora nk'ingabo ikingira ibintu byangirika nk'amazi na ogisijeni. Hatariho iyi nzitizi yo gukingira, ibyuma bikunda kubora no kwangirika. Mugushyiramo chromium, ibyuma bidafite ingese byunguka birwanya kwanduza, kwanduza, no gutobora, bituma kuramba no kwizerwa mubidukikije bitandukanye.

Byongeye kandi, kuba chromium yongerera imbaraga imbaraga nicyuma. Ibi bintu bivangavanze bitezimbere ibyuma byubukanishi, bigatuma birushaho gukomera no gukomera ugereranije nicyiciro gisanzwe cyicyuma. Imikoranire hagati ya chromium nibindi bintu bivanga itunganya microstructure yicyuma kitagira umwanda, bikavamo imikorere iranga imikorere.

Mu nganda kuva gutunganya ibiryo kugeza mubwubatsi, imiterere idasanzwe yicyuma ituma ihitamo neza mubikorwa byingenzi. Ubushobozi bwo guhangana n’imiterere mibi, kubungabunga amahame y’isuku, no kurwanya imiti y’imiti bishimangira akamaro ka chromium mu gukora ibyuma bitagira umwanda. Byaba bikoreshwa mubikoresho, ibikoresho byubuvuzi, inyubako zubatswe, cyangwa ibice byo mu kirere, guhinduranya ibyuma bitagira umwanda biva mubigize chromium ikungahaye.

Mu gusoza, gushyiramo byibuze chromium yibirimo 10.5% itandukanya ibyuma bitagira umwanda na bagenzi babo basanzwe. Ibi bintu bivanga imbaraga biha ibyuma imbaraga zo kurwanya ruswa, kuramba, nimbaraga, kubitandukanya nkibikoresho bihebuje mubikorwa bitandukanye byinganda n’imbere mu gihugu. Ihuriro rya siyanse na metallurgie mu gukora ibyuma bidafite ingese bishimangira uruhare rukomeye rwa chromium muguhindura ibikorwa bya kijyambere nubuhanga.
