Metal corrosion inoreva kuparadzwa kwesimbi inogadzirwa nemakemikari kana electrochemical chiito chepakati yakapoteredza, uye kazhinji pamwe chete nemuviri, mechanical kana biological zvinhu, kureva, kuparadzwa kwesimbi pasi pekuita kwezvakatipoteredza.
Mhando dzakajairwa dzesimbi corrosion yeplate heat exchanger ndeaya anotevera:
Uniform corrosion munzvimbo yese yakavhurika kune yepakati, kana munzvimbo yakakura, iyo macro uniform corrosion damage inonzi uniform corrosion.
Kuora kwakakomba kunoitika mumikaha uye zvikamu zvakavharwa zvesimbi.
Bata ngura Marudzi maviri esimbi kana alloy ane akasiyana anogona kuonana, uye akanyudzwa mu electrolyte solutive mhinduro, pane ikozvino pakati pawo, kukora kwehuwandu hwesimbi inogoneka kunoderera, kukora kweiyo yakaipa simbi inogona kuwedzera.
Erosion corrosion Erosion corrosion imhando yekuora inokurumidza kuita ngura nekuda kwekufamba kuri pakati pepakati nesimbi.
Selective corrosion Chiitiko chekuti chimwe chinhu chiri mualloy chinoitwa ngura kupinda pakati chinonzi selective corrosion.
Pitting corrosion yakatarisana netudiki tudiki pane simbi yakadzama yecorrosion inonzi pitting corrosion, kana pore corrosion, pitting corrosion.
Intergranular corrosion Intergranular corrosion imhando yecorrosion inonyanya kukanganisa muganho wezviyo nenzvimbo iri padyo nemuganho wezviyo wesimbi kana alloy, ukuwo zviyo pachazvo zvisinganyanyi kuita ngura.
Kuparara kweHydrogen Kuparadza kwesimbi mumagetsi emagetsi emagetsi nehydrogen infiltration anogona kuitika semugumisiro wekuora, pickling, cathodic kudzivirira, kana electroplating.
Stress corrosion fracture (SCC) uye corrosion kuneta ndiko kutyoka kwezvinhu kunokonzerwa nekubatana kwekuita ngura uye kushushikana kwesimba mune imwe simbi-yepakati system.
