GH4033 Nickel Alloy: Matla a Ikhethang le Ho hanyetsa Corrosion

Letoto la Superalloy

Lekola matla a ke keng a lekanngoa le ho hanyetsa ho bola ha GH4033, superalloy e thehiloeng ho nickel e etselitsoeng lits'ebetso tse sebetsang hantle maemong a feteletseng. E entsoe ka motsoako o ikhethang oa nickel, chromium, cobalt le molybdenum, GH4033 e fana ka thepa e phahameng ea mochini le khanyetso e ikhethang ea oxidation le kutu maemong a mocheso a phahameng. Matla a eona a hlollang le ho tšoarella ha eona ho etsa hore e be khetho e nepahetseng bakeng sa lisebelisoa tsa sefofane, lienjine tsa turbine ea khase, lisebelisoa tsa ho sebetsana le lik'hemik'hale, le lisebelisoa tse ling tse boima moo ho tšepahala ho leng bohlokoa haholo. Ka GH4033, o ka tšepa ho ts'epahala le ts'ebetsong ea likarolo tsa hau tsa bohlokoa, esita le maemong a thata ka ho fetisisa a ts'ebetso. Eba le bokhoni bo ikhethang ba GH4033 bakeng sa merero ea hau ea boenjiniere e thata ka ho fetisisa.
