Ulwahlulo lwemibhobho yensimbi engenasici luvela phi?

Kwiimibhobho yentsimbi engenasici, intsimbi ekwaziyo ukumelana nokudleka ngenxa yemithombo yemithombo yeendaba ebuthathaka njengomoya, umphunga, namanzi, kunye nezinto eziyingozi kwimichiza efana neasidi, ialkali, netyuwa, ikwabizwa ngokuba yintsimbi enganyangekiyo ekwaziyo ukumelana neasidi.Kwizicelo ezisebenzayo, iintsimbi ezixhathisayo kumajelo eendaba ezonakalisayo zidla ngokubizwa ngokuba yintsimbi engatyiwa, kwaye iintsimbi ezixhathisayo kwimidiya yekhemikhali zibizwa ngokuba yintsimbi enganyangekiyo kwiasidi.Ngenxa yomahluko kukwakheka kweekhemikhali phakathi kwezi zimbini, eyokuqala ayinyanzeli ukubola ngamajelo eendaba ekhemikhali, ngelixa le yokugqibela ingenabala.

Okwesibini, ukunyanzeliswa kwe-corrosion yeepayipi zensimbi ezingenasici kuxhomekeke kwizinto ezixutywayo eziqulethwe kwintsimbi.I-Chromium yinto esisiseko yentsimbi engatyiwayo ukufumana ukuxhathisa ukudleka.Xa umxholo we-chromium kwintsimbi ufikelela malunga ne-1.2%, i-chromium isebenzisana ne-corrosion.Umphumo we-oksijini kwizinto zenza ifilimu encinci ye-oxide ebusweni bentsimbi, enokuthintela ukubola kwentsimbi.I-substrate iphinda idliwe.Ukongeza kwi-chromium, i-alloying elements esetyenziswa ngokuqhelekileyo yi-nickel, i-molybdenum, i-titanium, i-niobium, ithusi, i-nitrogen, njl.
