Simbi isina ngurainozivikanwa nekusaita ngura, asi haina kudzivirirwa zvachose nekuita ngura. Simbi isina tsvina inogona kuita ngura mune mamwe mamiriro, uye kunzwisisa kuti sei izvi zvichiitika kunogona kubatsira kudzivirira uye kubata ngura.
Simbi isina simbi ine chromium, iyo inoumba mutete, passive oxide layer pamusoro payo kana yasangana neokisijeni. Iyi oxide layer, inozivikanwawo se "passive layer," inopa iyo corrosion resistancesimbi isina nguraine mukurumbira we.
Zvinhu Zvinokanganisa Ngura paStainless Simbi:
Kuratidzira kune Chlorides
Mechanical Kukuvadza
Kushaya Oxygen
Kusvibiswa
High Tembiricha
Hunhu Husina Stainless Simbi
Harsh Chemical Environments
Mhando dzeStainless Steel Corrosion:
Kune marudzi akasiyana e-stainless steel corrosion. Chimwe nechimwe chazvo chinopa matambudziko akasiyana uye chinoda kubata kwakasiyana.
General corrosion-ndicho chinotarisika zvakanyanya uye chiri nyore kubata. Iyo inoratidzirwa nekurasikirwa kweyunifomu yepasi rose.
Galvanic Corrosion- rudzi urwu rwekuora runokanganisa akawanda masimbi alloys. Inoreva mamiriro ezvinhu apo simbi imwe inosangana neimwe uye inoita kuti imwe kana zvose zvibatane uye zvigora.
Pitting corrosion– imhando yecorrosion yenzvimbo inosiya makomba kana maburi. Inowanikwa munzvimbo dzine chlorides.
Crevice corrosion- zvakare corrosion yenzvimbo inoitika pamukaha pakati penzvimbo mbiri dzinobatana. Zvinogona kuitika pakati pesimbi mbiri kana simbi uye isiri-simbi.
Dzivirira simbi isina simbi kubva kuita ngura:
Geza simbi isina tsvina nguva nenguva kuti ubvise zvinosvibisa uye uchengetedze dura rayo rekudzivirira.
Dzivisa kufumura simbi isina tsvina kune chlorides uye makemikari ane hasha.
Chengetedza simbi isina tsvina kubva mukukuvadzwa kwemichina uchishandisa mabatiro akakodzera uye nzira dzekuchengetedza.
Ita shuwa kufefetedza kwakaringana munzvimbo dzinoshandiswa simbi isina tsvina kuchengetedza mazinga eokisijeni.
Sarudza yemhando yepamusoro-stainless simbi ine yakakodzera alloy kuumbwa kwechinodiwa application.
