Insimbi engenasici inamandla okugqwesa phakathi equlethe i-asidi, i-alkali kunye netyuwa, oko kukuthi ukuxhathisa i-corrosion; Kananjalo inamandla okumelana ne-oxidation ye-atmospheric, oko kukuthi, umhlwa; Nangona kunjalo, ubukhulu bokumelana nokubola kwayo kuyahluka kunye nokwakheka kweekhemikhali zentsimbi ngokwayo, iimeko zokusetyenziswa kunye nohlobo lweendaba zokusingqongileyo. Okufana ne-304 yensimbi engenasici, kwindawo eyomileyo necocekileyo inokumelana ne-corrosion egqwesileyo, kodwa xa ihanjiswe kwindawo yolwandle, iya kugqwala ngokukhawuleza kwinkungu yolwandle equlethe ityuwa eninzi; Izinto ezingama-316 zinentsebenzo entle. Ngoko nakuphi na okusingqongileyo akukho naluphi na uhlobo lwensimbi engenasici ayinakugqwala.
Umphezulu wentsimbi ecocekileyo wenze umaleko wefilim ebhityileyo kakhulu kwaye eyomeleleyo ecolekileyo ezinzileyo yechromium oxide, emva koko ifumane isakhono sokuxhathisa umhlwa. Kanye ngenxa yesizathu esithile, le filimu ihlala yonakaliswa. I-athomu ze-oxygen emoyeni okanye ulwelo luya kuqhubeka nokungena okanye ii-athomu zentsimbi kwintsimbi ziya kuqhubeka zihlukana, ukubunjwa kwe-oxide yensimbi ekhululekile, ubuso besinyithi buya kuhlala buyi-corrod, ifilimu ekhuselayo yensimbi engenasici iya kutshatyalaliswa.
Iimeko ezininzi eziqhelekileyo zentsimbi ye-corrosion kubomi bemihla ngemihla
Umphezulu wensimbi engenasici uqokelele uthuli, oluqulethe izihlomelo zezinye iinqununu zetsimbi. Kumoya omanzi, amanzi e-condensate phakathi kokuqhotyoshelweyo kunye nensimbi engenasici iya kudibanisa ezimbini kwi-microbattery, ngaloo ndlela ibangele ukusabela kwe-electrochemical reaction, ifilimu ekhuselayo iyatshatyalaliswa, ebizwa ngokuba yi-electrochemical corrosion; Umphezulu wensimbi engenasici unamathela kwiijusi ze-organic (ezifana neemelon kunye nemifuno, isuphu ye-noodle, i-phlegm, njl.), kwaye zenza i-organic acids kwimeko yamanzi kunye ne-oxygen.
Umphezulu wensimbi engenasici uya kubambelela kwi-asidi, i-alkali, izinto zetyuwa (ezifana nokuhombisa udonga lwealkali, ukuchaphaza kwamanzi ekalika), okubangela ukubola kwendawo; Kumoya ongcolisekileyo (ofana ne-atmosfera equlethe izixa ezikhulu zesulfide, i-carbon oxide kunye nenitrogen oxide), i-asidi ye-sulfuric, i-nitric acid kunye ne-acetic acid iya kubumba xa idibene namanzi adibeneyo, ngaloo ndlela ibangela ukubola kweekhemikhali.
Zonke ezi meko zingentla zingonakalisa ifilimu ekhuselayo ebusweni bensimbi engenasici kwaye ibangele i-rust. Ngoko ke, ukuze kuqinisekiswe ukuba umgangatho wesinyithi ukhanya kwaye ungagqwali, sincoma ukuba indawo yensimbi engenasici kufuneka ihlambuluke kwaye ihlanjululwe ukuze isuse izinamathiselo kunye nokuphelisa izinto zangaphandle. Ummandla wolwandle kufuneka usebenzise i-316 insimbi engenasici, izinto ze-316 zinokuxhathisa ukubola kwamanzi olwandle; Ezinye iikhemikhali zepayipi yensimbi engenasici kwimarike ayikwazi ukuhlangabezana nemigangatho ehambelanayo, ayikwazi ukuhlangabezana neemfuno zezinto ze-304, nayo iya kubangela ukugqwala.
