Alloy e hanyetsanang le Corrosion
Lintho tse ka sehloohong tsa alloying ke koporo, chromium le molybdenum. E na le thepa e ntle e akaretsang 'me e hanela kutu e fapaneng ea acid le khatello ea maikutlo. Tšebeliso ea pele-pele (e hlahisitsoeng United States ka 1905) ke motsoako oa nickel-copper (Ni-Cu), o tsejoang hape e le Monel alloy (Monel alloy Ni 70 Cu30); ho phaella moo, motsoako oa nickel-chromium (Ni-Cr) (ke hore, alloy e hanyetsanang le mocheso e thehiloeng nickel), li-alloys tse hanyetsanang le mocheso ka li-alloys tse hanyetsanang le ho bola), li-alloys tsa nickel-molybdenum (Ni-Mo) (haholo-holo). e bua ka letoto la Hastelloy B), li-alloys tsa nickel-chromium-molybdenum (Ni-Cr-Mo) (haholo-holo e bua ka letoto la Hastelloy C), joalo-joalo.
Ka nako e ts'oanang, nickel e hloekileng e boetse e le moemeli ea tloaelehileng oa li-alloys tse thibelang ho bola ha nickel. Li-alloys tsena tse hananang le ho bola tse thehiloeng ho nickel li sebelisoa haholo ha ho etsoa lisebelisoa bakeng sa libaka tse fapaneng tse sa jeng joalo ka petroleum, lik'hemik'hale le matla a motlakase.
Li-alloys tse hanyetsanang le kutu tse thehiloeng ho nickel hangata li na le sebopeho sa austenite. Boemong ba tharollo e tiileng le phekolo ea botsofali, ho boetse ho na le mekhahlelo ea intermetallic le carbonitrides ea tšepe holim'a matrix a austenite le meeli ea lijo-thollo tsa motsoako. Li-alloys tse fapaneng tse hanyetsanang le kutu li arotsoe ho latela likarolo tsa tsona mme litšoaneleho tsa tsona ke tse latelang:
Khanyetso ea kutu ea Ni-Cu alloy e molemo ho feta ea nickel ho fokotsa mahareng, 'me khanyetso ea eona ea kutu e betere ho feta ea koporo sebakeng sa oxidizing. Thepa e ntle ka ho fetisisa ea li-acids (sheba Metal Corrosion).
Ni-Cr alloy e boetse e le motsoako oa nickel o hanyetsanang le mocheso; e sebelisoa haholo-holo maemong a mahareng a oxidizing. E hanana le oxidation ea mocheso o phahameng le ho bola ha likhase tse nang le sebabole le vanadium, 'me khanyetso ea eona ea kutu e eketseha ka keketseho ea chromium. Li-alloys tsena li boetse li na le khanyetso e ntle ea hydroxide (joalo ka NaOH, KOH) corrosion le khatello ea khatello ea maikutlo.
Li-alloys tsa Ni-Mo li sebelisoa haholo-holo tlas'a maemo a ho fokotsa kutu e mahareng. Ke e 'ngoe ea li-alloys tse ntle ka ho fetisisa bakeng sa ho hanyetsa kutu ho hydrochloric acid, empa ka pel'a oksijene le li-oxidants, ho hanyetsa kutu ho fokotseha haholo.
Motsoako oa Ni-Cr-Mo(W) o na le thepa ea alloy e boletsoeng ka holimo ea Ni-Cr le Ni-Mo alloy. Haholo-holo e sebelisoa tlas'a boemo ba oxidation-fokotso motsoako motsoako. Li-alloys tse joalo li na le khanyetso e ntle ea kutu mochesong o phahameng oa hydrogen fluoride, ka hydrochloric acid le hydrofluoric acid e nang le oksijene le li-oxidants, le khase ea chlorine e metsi mocheso oa kamore. Ni-Cr-Mo-Cu alloy e na le bokhoni ba ho hanela nitric acid le sulfuric acid corrosion, hape e na le khanyetso e ntle ea kutu ho tse ling tsa li-oxidative-reductive mix acid.
